Tulip Olsen
I’m getting off this train!
Voiced by: Ashley Johnson

Tulip is the main protagonist of the show, a 12-year-old girl who's trying to leave the Infinity Train and figure out the mystery of the glowing green number on her hand.

  • Action Survivor: Though not all of the cars rely around surviving danger obviously, Tulip still manages to hold her own and figure out multiple hazardous situations after coming to terms with being in danger.
  • Adorkable: Most definitely.
  • Affectionate Nickname: Her parents call her "Bud".
  • Arbitrary Skepticism: One-One, perhaps unwittingly, calls out Tulip on this when she thinks the number on her hand could have no relation to the monster menacing Corginia.
    Tulip: It's just so unlikely...
    Sad-One: Unlikely like a fart car.
  • Badass Bookworm: She's both intelligent and athletically gifted. According to Word of God, she could join a sports team with ease, if she wanted to.
  • Badass Normal: For a twelve-year-old girl way in over her head on the train, Tulip acclimates rapidly to dangerous scenarios and does her best to resolve them while not only being quick on the uptake about puzzles but also surprisingly nimble. This culminates in a direct fight with the Conductor/Amelia, hitting a moving Ghom'd Atticus with a focused shot to revert him to normal, and even getting a good hit on Amelia's cockpit while not getting hit at all.
  • Bizarre Taste in Food: Enjoys eating whole raw onions the way one would eat an apple. She calls it "having a sophisticated palate".
  • Child Prodigy: Tulip is an expert coder/programmer, even having made her own video game. She also knows words that are "outside her peer group".
  • Claimed by the Supernatural: When Tulip enters the train, she has a glowing green number on her hand.
  • Deadpan Snarker: She does snark to herself from time to time when she gets annoyed or frustrated.
  • Determinator: When her parents can't drive her to coding camp, she decides to walk there herself, which starts her adventure on the train.
  • Disappeared Dad: In this case, her parents are divorced and she lives with her mom with her dad rarely coming by for visits.
  • Early Installment Character-Design Difference: In the pilot, she had big glasses and large eyes. Both of these shrunk in the official show, with Tulip's eyes slightly resembling the eyes seen on some Craig of the Creek characters. Also, her boots were grey in the pilot but became blue in the TV series, and her skirt also became longer.
  • Epiphanic Prison:
    • The videotape in "The Cat's Car" tries to trap her in a Lotus-Eater Machine of her memories. Tulip gets out by confronting the fact that her happy memories weren't really as happy as she'd like, but also that her parents' divorce, as much as it hurt, really wasn't her fault, and isn't something she needs to lie to herself about.
    • The Train itself is this to her, the number on her hand represents her unresolved issues, and when she deals with them all, her door appears, leading her home.
  • Expository Hairstyle Change: Seven months after she returns home, her bangs are swept over to the left and her hair is noticeably shorter.
  • Fatal Flaw: Her biggest flaw is her refusal to actually confront and work through her emotions, instead preferring to ignore them, deflect, and try to bury them."The Cat's Car" is all about her confronting this fact about herself.
  • Fiery Redhead: When it comes to her parents' divorce, she has a very thin temper.
  • Foil:
    • According to Word of God, Tulip is intended to be a foil to the Infinity Train itself. The Infinity Train is bizarre and illogical, which contrasts with Tulip's need for everything to be logical and make sense.
    • She's also one for the Conductor, since both are Control Freaks in a sense, who want the world to do their bidding. The main difference is that Tulip understands and eventually accepts that life can't always go her way. She also cares about the friends she makes on her journey while the Conductor is a sociopath who sees the character on the train as puppets who have to stay in their cars for all eternity. If they rebel, they'll turn them into Ghoms without hesitation, in direct contrast to Tulip, who encourages them to explore. Just like Tulip, the Conductor/Amelia was also a person who entered the train, but while Tulip was able to make friends and lower her number by resolving her issues, Amelia just became more and more obsessed with what she had lost, thus increasing her number to an amount that has crawled up to her neck and eventually taking control of the train itself in a desperate attempt to recreate her old life and her lost love in one of its cars, which Tulip is able to reject when Amelia offers to do the same for Tulip, creating a world where her parents were still together, because she knew that it wouldn't be real.
  • Gamer Girl: She's shown creating her own video game.
  • Giver of Lame Names: The characters in her video game are "Good Guy" and "Bad Guy". The name itself is named "Good Guys Popping Bad Guys".
  • Hair Decorations: She wears a small yellow barrette in her hair.
  • Hypocritical Humor: When One-One first tells her his name, Tulip comments that it's an unusual name, unlike her own. Except that "Tulip" is an unusual name. It's Played for Laughs, and the Cat spends a good portion of the series mocking her "perennial" name.
  • I Choose to Stay: Despite having resolved all her personal issues keeping her on the Train by "The Past Car", she puts off leaving to save Atticus.
  • In-Series Nickname: She's regularly called "Ms. Tulip" by One-One and "Tulip the Literate" once by Atticus. Kate Mulgrowl the Cat also calls her "kitten" from time to time.
  • I Reject Your Reality: Her memories about the past are a lot more rose-colored than is probably true — but her memories of pain, such as her parents' separation, are worse than the mundane dinner-table discussion they actually had. The videotape prison in "The Cat's Car" forces her to confront the fact that her parents' marriage was troubled, but that they really did want the best for her and that her pain was reasonable.
  • Irony: Her hair is a bright orange/red and tulips in those colors can either symbolize happiness or love. She certainly doesn't have any of that in her life or else she wouldn't have been on the train, now would she?
  • Jerkass: Her defining characteristic at the beginning of the series. Between the three main characters, she's easily the most aggressive, impatient, irritable, and above all else tends to lock away how she really feels which leads to a multitude of social issues. By the end of the series the Jerkass part is all but gone entirely, leaving her as quite the Nice Girl. Turns out the train did her a lot of good in the end.
  • Jerkass Realization: Realizes in "The Cat's Car" that she's been demonizing her parents over their divorce when in reality they were as torn up by it as she was.
  • Jerk with a Heart of Gold: Regardless of this, she's also supportive, loyal, and cares deeply about those around her, and the entire series is her evolving past her biggest issues.
  • Locked into Strangeness: The ending of season 1 shows that Tulip's reflection really didn't come back, and she certainly hasn't lost her memories.
  • Logical Latecomer: As the newest arrival on the train, she questions everything that happens on it.
  • The Magnificent: Atticus calls her "Tulip the Literate" when they first meet.
  • Meaningful Name: Discussed. When One-One asks if she's called "Tulip" because she has a big bulbous head, she explains that when she was born she had breathing problems, but she bounced back "like a perennial flower", so her parents named her Tulip after said flower.
  • Meganekko: Tulip is very cute and wears a pair of glasses.
  • Missing Reflection: While it's not obvious after the Chrome Car, the final episode shows that Tulip no longer has her reflection even when returning to the real world.
  • Parental Issues: Her parents are divorced and you can tell by the first episode alone that this is having an effect on her. By the finale, it doesn't affect her anymore.
  • Redhead In Green: Wears a green hoodie as part of her outfit. Her hairclip is also the same color. She also wore a green shirt in the family photo from her vacation at DolphWorld.
  • The Runaway: Played with. She planned to go to Game Design Camp by herself after both of her parents declined, without telling anyone.
  • Shmuck Bait: Tulip had absolutely no reason to trust the Cat, and the entire setup reeked of a trap, but the idea of a videotape with all the answers (and her name on it) was too much to resist.
  • Shut Up, Hannibal!: When Amelia tries to win her over by offering to create a car where her parents are still together, Tulip shoots her down by pointing out her failure to even create a car without any turtles in it.
  • Smart People Play Chess: In the pilot, one of the previous cars Tulip puzzled her way through was built around chess pieces. On the floor, walls, and ceiling. In the show proper, she was heading for programming camp before winding up on the train.
  • Smart People Wear Glasses: Tulip is interested in coding, and wears U-framed glasses.
  • Trademark Favorite Food: Onions. She's shown eating them like one bites into an apple.
  • Workaholic: A child variant. She's completely obsessed with finding out all of the rules of the train, because she fears that the train might kill her if she breaks one. However, she can get so into it that it overwhelmed One-One.


Voiced by: Jeremy Crutchley (Glad-One) and Owen Dennis (Sad-One)

A spherical robot who's been on the Infinity Train their whole life. Is made up of two individual personalities called Glad-One and Sad-One. The two can split down the middle to function independently.

Tropes applying to both:

  • All There in the Script: The different personalities are referred to in the scripts as "Glad-One" and "Sad-One", for the sake of writing and voicing the characters. In-series, they've only identified themselves as "One" and "One", with others always calling them the tandem "One-One". In the finale, Amelia suggests their name, before her usurpation, was simply "One".
  • Ambiguous Situation: How important are they in the grand scheme of things? Between the Steward's vested interest in them and their reaction to the Unfinished Car, it's implied that they have a bigger purpose for being on the train than what's been shown so far. They're revealed to be the real Conductor in "The Engine", Amelia having usurped them.
  • Be the Ball: They're two halves of a spherical robot.
  • Big Good: Revealed to be this as the train's true conductor at the end of the season. Unlike Amelia, they are truly benevolent and just want the passengers to make peace with their personal demons.
  • Bread, Eggs, Breaded Eggs: This moment when One-One solves the weight puzzle:
    Glad-One: Yay, yay us! Yus!
    Sad-One: No. Nus.
  • Cloudcuckoolander: Many of their mannerisms and sayings come across this way, such as when they repeatedly ask various beings and objects whether they are their mother. Much of their behavior makes more sense when it is revealed that they are the true Conductor of the train.
  • The Dividual: Of the Syndividual type. The Ones have contrasting personalities but are never seen apart.
  • Identity Amnesia: After being usurped as the Conductor by Amelia, although they remember many facts about the Train, they don't remember their true role onboard until they make it back to the Engine with Tulip's help.
  • Light Is Good: Is a white spherical robot and the true Conductor of the train.
  • Literal Split Personality: Glad-One and Sad-One.
  • MacGuffin Person Reveal: The Conductor really wants them destroyed, as it turns out One-One is the original Conductor.
  • Missing Mom: In the first episode of the series when Tulip first encounters them with the snowmen, they mention looking for their mother but having no idea what she looks like. Because the mother they're talking about is the motherboard of the train.
  • O.O.C. Is Serious Business: When they reach the Unfinished Car, One-One suddenly drops everything to "fix" it, not even caring that they're damaging the car and its inhabitants. When Tulip tries to stop them, the halves start speaking in unison, something they'd never done before then.
  • Portmanteau: Tulip creates their name from the names of each of their personalities, both of which are "One".
  • Robot Buddy: Naturally.
  • Walking Spoiler: The ending changes everything about this little robot's character.

Tropes applying to Glad-One

Are you my mum?
  • Dissonant Serenity: Their perpetually cheerful demeanor can occasionally be off-putting when the circumstances take a turn for the grim.
    The Cat: I thought if I found you I'd be left alone.
    Glad-One: That's funny! That didn't work at all! [laughs uproariously]
    The Cat: No. It didn't.
  • The Ditz: Moreso than Sad-One.
  • The Pollyanna: Not much gets them down. This is especially apparent when compared to their other half.

Tropes applying to Sad-One

So you’ve come to bring me the sweet release of death?
  • Blunt "Yes": Sometimes when they say something morbid or do something, it's usually followed up by a blunt or a deadpanned yes.
  • The Comically Serious: Sad-One speaks in a monotone and often is The Eeyore. They also have some of the funniest one-liners.
  • Deadpan Snarker: They're usually the snarkiest of the group next to Tulip.
  • The Eeyore: Perpetually depressed and cynical, especially when compared to their other half.
    Atticus: Awfully morbid little thing, aren't you?
    Sad-One: Yes.


It’s dangerous to go in alone.
Voiced by: Ernie Hudson

A talking corgi who rules Corginia, an entire land of talking corgis in one of the Infinity Train's cars.

  • Ancient Grome: His culture is very much Athens-inspired while his own name is Latin.
  • Badass Adorable: Isn't he just the cutest heroic corgi you ever saw?
  • Baleful Polymorph: In "The Ball Pit Car", the Conductor punishes him for leaving his car and siding with Tulip by turning him into a Ghom.
  • Black Bead Eyes: His eyes, like the other corgis, are drawn like this.
  • Breakout Character: In an early interview with RebelTaxi, Owen Dennis commented that he had no immediate plans to make Atticus a main character, despite the positive fan reaction he received. Jump forward to the premiere and Atticus is very much a main character.
  • Civilized Animal: He's the leader of a small kingdom of talking dogs.
  • The Comically Serious: His wisdom and seriousness is bellied by the fact he is still a corgi, and acts accordingly.
  • Cool Crown: He wars a small dome shaped crown over his head and when Tulip manages to turn him back to normal, she places the crown back on his head and he admits he felt odd without it on.
  • Face–Monster Turn: After the Conductor turns him into a Ghom in "The Ball Pit Car". He gets better.
  • Fate Worse than Death: His transformation into a Ghom, which erases his entire personality and appears to be a painful process. However, Tulip does find a way to turn him back to normal by the final episode.
  • Female Feline, Male Mutt: As the King of Corginia he is most definitely the male mutt to Mulgrowl the female feline.
  • Gory Discretion Shot: When the Conductor shoots Atticus.
  • Heroic Dog: Is an adorable corgi who is also one of the good guys.
  • Heroic Sacrifice: In "The Ball Pit Car", he distracts the Steward to give Tulip and One-One the chance to escape. He survives this, but is then captured by the Conductor and turned into a Ghom.
  • It's Personal with the Dragon: The reason he joins the group is to hunt down the Steward and ensure she never threatens his kingdom again and fights her in all her appearances. He's ultimately the one to destroy her in the end.
  • The Magnificent: His full title is "Atticus, King of the Corginians, and Uniter of the Cardigans and the Pembrokes".
  • My Instincts Are Showing: To his embarrassment, he still acts very much like a corgi who likes belly rubs and eats spiders.
  • Only Sane Corgi: With Tulip usually on the edge of a nervous breakdown and One-One being One-One, it's usually Atticus that is the calm voice of reason.
  • Royals Who Actually Do Something: Atticus personally joins Tulip to defeat the monster, and braves the Steward's machine gun fire in a valiant (but ultimately futile) attempt to attack it. He subsequently fights the Steward every time it threatens the heroes and is eventually the one who destroys it.
  • Sacrificial Lion: He is transformed into a Ghom in "The Ball Pit Car", bringing about the Darkest Hour in the series. Fortunately, Tulip turns him back in the season finale.
  • Seldom Seen Breed: His tail identifies him as a Cardigan Welsh Corgi, which are more rarely seen in media compared to their Pembroke counterparts.
  • Turning Back Human: Or corgi, in this case. In the final episode Tulip finds the gun used on Atticus, inserts a corgi orb, and manages to turn him back to his original form.

The Main Antagonists

    The Steward 

The Steward
Return to your seat.
Voiced by: Ashley Johnson

A robotic Steward who Tulip encounters in Corginia.

  • The Brute: It's the Conductor's enforcer. Denizens of the train who know what it is are terrified of it.
  • The Dragon: It's working for the Conductor. "The Cat's Car" is the first time we see it apparently taking orders.
  • Fireball Eyeballs: The Steward has blue flame coming out of its eye sockets. Behind the mask is a tube generating the flame.
  • Imperial Stormtrooper Marksmanship Academy: Despite being equipped with machine guns, it never actually seems to hit anything with them. Probably justified, since it isn't a combat robot but a Train service bot.
  • Light Is Not Good: It has a cherubic face and shoots blue fire, but it serves an evil master.
  • Nice Job Fixing It, Villain!: The Steward tosses Atticus next to the broken pipes. While it goes after Tulip, he manages to turn off the water to stop the flooding.
  • Non-Malicious Monster: It doesn't seem to have much intent of its own, acting solely on the orders of the Conductor.
  • Off with His Head!: Atticus finally destroys it by destroying its head while bursting out of his Ghom form.
  • Sliding Scale of Robot Intelligence: Unlike One-One it appears to be completely non-sentient, requiring directions from the Conductor in order to take any action.
  • Starfish Robots: It's a humanoid face that moves around on tentacles.
  • You Have Failed Me: All signs indicate that its retaliation against the Cat for failing to detain Tulip was going to be pretty graphic.

    The Ghoms 

The Ghoms

Dog/cockroach hybrids that chase down anyone who tries to leave the Infinity Train. They appear to have the ability to drain the life out of other beings.

  • All There in the Script: The name "Ghom" isn't used in-show, instead coming from the credits.
  • Dark Is Evil: Unlike the main villains they are constantly cast in shadow, making their real forms hard to discern and all the more unsettling when they are revealed.
  • Mix-and-Match Critters: They're basically cockroaches with the size and legs of dogs. The episode recap video Cartoon Network put out also describes them as being robotic.
  • Life Drinker: They suck out some kind of energy from Tulip, causing her to wither, though the effect is reversed once she breaks free.
  • Shout-Out: They're named after the Lord of Gluttony from Diablo. Fitting since they feed on one's life force.
  • Stronger Than They Look: Atticus, when turned into a Ghom was able to fight the Steward to a standstill.
  • Was Once a Man: Zig-zagged; the Conductor turns Atticus into a Ghom, but did so using a weapon that turns anything into whatever's orb is inside it, making it ambiguous if Ghoms exist any more "naturally" than other creatures in the train. The Reddit question segment confirms that not all rebellious passengers were turned into them.

    The Conductor (Warning! Spoilers!) 

Amelia Hughes/The Conductor

Voiced by: Lena Headey (Amelia Hughes), Matthew Rhys (robot suit)

The person or entity apparently running the train at the engine. Getting to the Conductor to get off the train is Tulip's Series Goal.

  • All for Nothing: Her attempt to bring back Alrick is this. No matter what she tries, the Train will not replicate the past and it's only making her sentence on the train longer than it should be due to how she's been hurting others.
  • Animal Motif: The turtle. Amelia has a handkerchief with a turtle on it and one of the failures of her unfinished car is a tree with turtles instead of leaves. This represents how she's unable to face the reality of losing Alrick by tucking herself into a shell both physically (the Conductor's form) and mentally (rejecting the notion that she can't have a life without Alrick). Thematically, the symbol for infinity can be represented by the world being carried by an infinite stack of turtles.
  • Bait-and-Switch: While we're lead to believe the person running away from the funeral is Alrick because of the hood — since he wore it in a previous flashback — when the hood falls down, it's revealed to be Amelia refusing to accept her husband's death and eventually stumbling upon the Train.
  • Berserk Button: They can't stand anyone not obeying them or acting as they think they should. She has the Steward try to kill the Cat seemingly purely because she questions her orders to go after One-One.
  • Big Bad: Turns out to be the one the Steward and the Cat answer to and who controls the train and everything in it.
  • Brainy Brunette: Amelia has light brown hair and was capable of creating multiple cars in the Infinty Train along with the Conductor's robotic suit. The first flashback in "The Past Car" had her work on a crystal radio.
  • Broke Your Arm Punching Out Cthulhu: Manages to hijack the Infinity Train... but ultimately only succeeds in making things worse for everyone and condemning herself to an extremely long stay on the train. The train itself didn't seem to be all that much affected by it and just continued doing as it always had relatively unimpeded without her input.
  • Can't Live Without You: Alrick's death really hit her hard. This is the entire reason why she hijacked the Infinity Train in the first place.
  • Cast as a Mask: Prior to The Reveal, The Conductor is voiced by Alrick's voice actor. Afterwards, they are voiced by Amelia's.
  • Control Freak: Their dialog implies this, with their hostility towards Tulip stemming from her "messing" with everything on the train. Interestingly, the flashbacks in "The Past Car" show that she was more of a free spirit when Alrick was alive, implying that her current obsession with control is a reaction to his death.
  • Chekhov's Skill: During the flashback in "The Past Car", Amelia is shown manipulating a payphone by playing specific tones on her recorder. She is shown manipulating the Steward the same way in the present day.
  • Childhood Friend Romance: Amelia and Alrick were classmates when they were children, they then eventually formed a romantic relationship and got married before Alrick passed away.
  • Darth Vader Clone: They're in a large, robotic suit, their voice is heavily modulated with a low, robotic buzz, wear a black cloak, and their motivations are rooted in the loss of a loved one.
  • Despair Event Horizon: Losing Alrick was what caused Amelia to enter the Infinity Train and begin the decades-long quest to bring him back as the Conductor. There's even an implication of her being Driven to Suicide by the loss, given that the train appeared to her on the roof of her old university.
  • Disproportionate Retribution: It seems that any stepping out of line with their orders or plans will earn you a horrible fate, no matter how minor. Her attempted murder of the Cat seemed to be solely motivated by her talking back to her before caving and trying to do what she ordered. In fact, their entire modus operandi is based on this. Angry that she is unable to have a car to herself based on her past life with her husband? Make sure nobody else ever gets to leave, torture the other passengers on the train into submession and make them just as miserable as she is if not more so.
  • Dramatically Missing the Point: Amelia completely ignored the lessons that the Train was trying to teach her and became obsessed with returning her life to the way it was before Alrick's death. Because of this, her number is so obscenely high that she likely will die of old age before she fulfills her Longer-Than-Life Sentence.
  • The Dreaded: Everyone who knows who more about them than their name are terrified of them. And rightfully so.
  • Dysfunction Junction: The size of a passenger's number represents the amount of problems in their life that they need to come to grips with before they can leave the train. Amelia's number is so long it wraps around her entire body.
  • Early-Bird Cameo: They can be seen in the very first episode after Tulip wakes up in the snow car.
  • Easily Forgiven: Subverted: while Tulip does forgive her, the Train itself doesn't let her off easily. She's going to be stuck there for a long time due to everything she did. At the very least, the Train does decrease her number count — which is up to her neck — by a little.
  • Evil Brit: Despite their voice being synthetic, there's more than a touch of a soft yet chilling English accent in their voice. This is because she is actually an Englishwoman.
  • Evil Cannot Comprehend Good: When Amelia sees that Tulip's gotten her number to 0, she's surprised that Tulip remained on the train to rescue Atticus, and refuses to back down even when faced with the threat of never seeing her door again.
  • Evil Is Bigger: They're the Big Bad and tower over everything else, even the Steward. Downplayed when her true nature is revealed, as she's still an adult woman and larger than Tulip.
  • Faux Affably Evil: They're soft-spoken and stoic even when threatening others or giving Tulip a vicious Breaking Speech, and brushes away Tulip's resultant tears with a mock-affectionate "no more tears" with a cloth.
  • From Nobody to Nightmare: Went from a grieving woman who lost her husband to the Conductor that ruins other passengers' lives in order to give herself meaning.
  • Happily Married: Was this with Alrick. Emphasis on was since Alrick died sometime after that.
  • Heel–Face Turn: In the end, Tulip manages to get through to her through empathy and get her to have a Heel Realization, although that doesn't mean she's completely off the hook.
  • Hero Killer: Nothing the heroes do against them so much as phases them and she reduces Atticus to a rampaging Ghom and leaves Tulip a sobbing wreck with a Breaking Lecture. In fact, due to said Ghom, had One-One not survived, she'd have inflicted a Total Party Kill then and there.
  • Hidden Agenda Villain: Exactly what they want is secret for nearly the entire series. She desperately wanted to recreate her deceased husband and get her old life back, and she tried to destroy One-One because he was the real Conductor and she didn't want him to retake control from her.
  • His Name Really Is "Barkeep": They're only called the Conductor for most of the series. When they finally appears in person, they introduce themself solely as such, implying it's their actual name. Subverted, as their name is really Amelia.
  • Hoist by His Own Petard: If Amelia hadn't intervened, Tulip would likely have managed to reach zero and return home long before reaching the engine, and she could have captured One-One without her getting in the way.
  • Hypocrite: The Conductor gives Tulip a speech about how everyone in the train has a place, and that it was Tulip's fault for One-One and Atticus getting hurt because she let them come along. The next two episodes reveal that the Conductor not only isn't a native of the train, meaning she doesn't belong on it, but that she usurped control of the train from One-One and shunted them off into another car, whereas One-One and Atticus joined Tulip by choice.
  • In the Hood: The Conductor is never seen without their dark hooded robe, likely for Amelia to keep the memory of her husband alive, as she also wears a dark hoodie inside the robot suit.
  • I Reject Your Reality: She wants nothing to do with her current situation and is desperately trying to create a car that replicates her past before Alrick was killed off. Unfortunately, the more she rejects the notion that she has to move on, the bigger the number on her hand grows, until it's already crawling up her neck.
  • Interrupted Suicide: Implied. As her last location in her tape showed her running across the rooftops of her college in order to avoid Alrick's funeral, it doesn't take much to guess what she was planning on doing had the train not appeared.
  • Karma Houdini: Subverted. Tulip forgives her for what she's done — which includes two huge Kick the Dog moments below — but the Train won't let her go until her number drops to 0. Given that said number has crawled up to her neck, she's gonna be there for the rest of her life.
  • Kick the Dog:
    • The Conductor is quite abusive to the Cat and orders the Steward to destroy all of the Cat's belongings for her failure. Near the end of the series, she orders the Cat to pursue One-One and then has the Steward open fire on the area.
    • Almost literally: she turns Atticus into a Ghom for no other apparent reason than being angry at him for not staying in his place. She then leaves him to dispose of Tulip.
  • Knight of Cerebus: The moment they or anything relating to them comes into play, the tone goes very dark very fast. Her formal introduction sees the party lose their first member.
  • Lack of Empathy: They have zero empathy for anything Tulip went through or the apparent deaths of her friends or even the other passengers on the train.
  • Laser-Guided Karma: By her own admission she was hit with this. All the horrible things she did during her long rule of the train ultimately amount to a number so long it reaches all the way to her neck (in comparison, the second highest passenger that is seen at more than 99,999 although it's later revealed that it's probably higher than that; Tulip herself had a measly 115) and it's unclear if she'll live long enough to finally be set free.
  • Light Is Not Good: They have a completely white body that can even camouflage in the light of day. And they are absolutely not a good thing.
  • Love Makes You Evil: She was in love with her husband, Alrick and turned evil just so she could have him back in some fashion. One-One said it best.
    One-One: Plato once said, "Love is a serious mental illness."
  • Meaningful Name: Amelia is based on the German word for "industrious", and boy has she been hard at work trying to get her husband back...
  • The Mourning After: After Alrick's death, Amelia refuses to confront it, and instead winds up on the train and spends the next how many years trying to make a car that recreates her old life with her husband in it.
  • Necromantic: She took over the train so she could make a room that replicates her life when Aldrick was still alive. Unfortunately, she's been unsuccessful.
  • Orcus on His Throne: Doesn't confront Tulip in person until the last three episodes. Justified, as the train is a gigantic place and finding Tulip is a difficult task. Also, Amelia largely just wants to be left alone to create a car where her husband is alive, and only comes after Tulip when it becomes apparent there's a chance she might lose control of the Train back to One-One.
  • Powerful and Helpless: Is the most powerful thing on the train with control over it and can create entire pocket worlds within the cars... but the train won't allow her to make the one thing she wants: her husband and life back.
  • Prefers the Illusion: She is actively trying to make an illusion of her husband good enough that it'll make her feel like he's alive again. When stuck in the same Lotus-Eater Machine that Tulip escaped, the Conductor gets out only through the Steward's intervention.
  • Ray of Hope Ending: Even though Amelia's number stretches all the way up her body and it seems highly unlikely that it would ever reach zero before she passed away from old age... the number still falls a couple dozen digits when Tulip assures her that there's still a chance to fix her mistakes.
  • Sadist: Woobie, Destroyer of Worlds or not, they really enjoy kicking people at their lowest point, like mocking Tulip's grief multiple times.
  • Samus Is a Girl: Despite the masculine voice, she's actually female. Even when we see her Start of Darkness, Tulip and the audience are initially fooled into thinking she's her deceased husband. Many traits of her Conductor persona emulate ones her husband had, implying she intentionally modeled it after him.
  • Shadow Archetype: She's essentially what Tulip would become if she didn't let go of the trauma caused by her parents' divorce and tried to get everyone else to do as she wants.
  • Stuffed into the Fridge: Subverted. We're initially led to believe that Amelia is the sacrificial victim, when actually it's her husband.
  • Unrobotic Reveal: She's actually a human woman in a Mini-Mecha.
  • The Usurper: There was a Conductor before her — One-One — and she usurped the train from them.
  • Villain of Another Story: How did a grieving widow usurp the Infinity Train?
  • Villainous Breakdown: After Tulip manages to get to the Engine and confront her, she begins to have a complete meltdown as she gets closer and closer to unraveling her plan.
  • Walking Spoiler: Anything beyond "they exist" is a late-game spoiler for the series.
  • Woman in White: She is a woman inside a white robot.
  • Woobie, Destroyer of Worlds: Underneath the imposing robot, she's actually a grieving widow unable to process her pain. She hijacked the train to try and force it to create a car that was exactly how her old life used to be yet being unable to get what she truly wanted. Her cruelty towards Tulip and her friends seemed to be a vain attempt to fill the void with something.
  • Would Hurt a Child: During their Villainous Breakdown, they're willing to attack Tulip for messing with everything. And given how she's been on the train for some time, and one of the passengers is a little girl, she's probably done this before.

The Train

    The Cat 

Kate "The Cat" Mulgrowl
Tell me, kitten. Do you want to get off this train?
Voiced by: Kate Mulgrew

A feline Tulip meets in "The Beach Car" who claims to be a friend of the conductor. Similar to Atticus, she can speak human, but she also wears a bit of clothing.

  • Ain't Too Proud to Beg: Being confronted by the Steward terrifies her.
  • Ambiguously Evil: She doesn't really do anything wrong in her first appearance save conning Randall and she seems to indicate she was intending to follow through on her deal with Tulip about talking to the Conductor, but she has a clear aura of untrustworthiness about her that eventually convinces Tulip not to follow through on the deal and try and get One-One back from her. "The Cat's Car" reveals that she's working with the Steward, though not completely willingly. Later, after nearly being killed by the Conductor and the Steward, she joins the good guys before leaving for good.
  • Androcles' Lion: She is genuinely baffled by Tulip pulling her out of the wreckage of the ball pit car and expecting nothing in return, so she gives Tulip the solution to Atticus' Baleful Polymorph and assists with moving the car to the front of the train.
  • Awesome Anachronistic Apparel: Wears some very tasteful clothes.
  • Back for the Dead: Returns in "The Ball Pit Car"… only to seemingly be killed by the Steward on orders from the Conductor. Subverted, though, when the very next episode reveals that she survived.
  • Bifauxnen: She's female, but wears plenty of masculine clothes.
  • Blue and Orange Morality: She doesn't function by what one would call a conventional moral code, acting based on a quid quo pro mentality that works in tandem with her Con Man Collector of the Strange lifestyle. She's seemingly obsessed with deals, to the point that nearly every interaction she has with others is phrased as a transaction or bargain. She considers breaking a prior deal to be a major transgression but will offer a return of services to someone who does something for her even if they disdain the offer. The idea of not getting something in return for doing something honestly baffles her and doing something free of charge is regarded as immensely generous on her end.
  • Cats Are Mean: She's a manipulative, antagonistic cat contrasted to the more trustworthy corgi, though to her credit she seemingly was willing to go along with her deal with Tulip and later was coerced into villainy. She later undergoes a Heel–Face Turn and helps the good guys before leaving for good, subverting this trope.
  • Collector of the Strange: Her car in episode 5 is full of random objects. She's very protective of them, as seen when she snaps at One-One for touching her globe of the Earth and later when the Steward smashes up part of her collection to punish her failure to capture Tulip.
  • Con Man: She's introduced tricking Randall the water creature into buying a pipe she advertises as a donut hole maker.
  • Dungeon Bypass: Her vehicle lets her ride on the top of the train cars, bypassing the rooms entirely.
  • Enemy Mine: She's not a bad guy, but she does team up with Tulip in the penultimate episode to get revenge on the Conductor.
  • Female Feline, Male Mutt: Is referred to with feminine pronouns, making her this to Atticus's Male Mutt.
  • Gratuitous French: The Cat peppers her already sesquipedalian vocabulary with random French phrases, such as bon appetit.
  • Honor Among Thieves: She may be a con artist, but she will repay her debts. Even when the person in question wants nothing in return.
  • Light Is Not Good: Is a pure white feline, but she's not a sweetheart. At best, she can be seen as Good Is Not Nice.
  • Lotus-Eater Machine: Her videotape, which was apparently a way to buy time until the Steward showed up.
  • No Name Given: When Tulip asks her what her name is, she identifies herself as THE Cat. Her name, Kate Mulgrowl, is a case of Ascended Fanon, which was granted a matter of hours before episode 10. Time will tell if her name is used in-show in the next season.
  • Nominal Hero: She decides to ultimately side with the good guys, albeit mostly to get revenge on the Conductor.
  • No Need for Names: She is THE Cat.
  • Overly Narrow Superlative: She refers to Tulip as "my favorite person arbitrarily named after a flower."
  • Spell My Name with a "The": As she tells Tulip in her final appearance.
    Tulip: Well, I guess... goodbye... Cat? Uh... is it "Cat"?
    The Cat: "The Cat."
  • Talking Animal: Like Atticus, she's an animal that can speak.
  • Unreliable Expositor: She seems to know something about Tulip's situation, given that she has a videotape of Tulip's memories and appears familiar with the numbers on her hand. That said, she's playing her cards close to the chest, so all of her advice (such as the fact that reducing the number is good) is suspect.

A creature in the beach car made of water that can also talk. He is first seen being conned by the Cat, and later helps Tulip save One-One.

  • Black Bead Eyes: The kind of eyes Randall has.
  • The Ditz: He’s either very gullible or has a strange way of valuing things. He instantly buys it when the Cat foists off a rusty pipe on him, calling it a “donut holer” after she pokes holes in a couple of things using it. It may be a general trait of water people, considering Tulip traded a gear she needed for a flower from a merchant and then later got said flower back for a pack of gum, the merchant being instantly enamored with both the flower and the gum and treating them as if they were rare treasures.
  • Elemental Embodiment: Is a water elemental with a somewhat goopy texture.
  • Making a Splash: He and his people (who are probably all extensions of himself) are made of water and can cause the sea to part.
  • Mellow Fellow: He generally talks in a mild tone and does not seem to get upset or excited easily. He even agrees to double-cross the Cat without much fanfare.
  • "Metaphor" Is My Middle Name: When Tulip asks if he can slip through the cracks, Randall says, "That's my middle name. Randall Slip-Through-The-Cracks Randall."
  • Self-Duplication: He can duplicate himself by splitting. It's uncertain whether each clone has a distinct consciousness or if he's just having conversations with himself.
  • Super Speed: He can keep up with and even overtake the Cat’s ball car magnet thing with no assistance and while carrying Tulip inside of him.
  • Uniformity Exception: Has a blade of grass floating inside him when he takes Tulip to a city of other water people (who otherwise look identical).



A humanoid flower who resides in the "Straight Up Italy"-Car. She owns a restaurant, Tulip helps her deliver her goods.

  • The Blank: She doesn't seem to have a face, or if she does, it's hidden in her petals.
  • Non-Human Head: She looks perfectly human, save for the head, which is a giant rose.
  • Plant Person: She has a rose for a head.

    Gambit, Tulip's Reflection 

Gambit, Tulip's Reflection

Voiced by: Ashley Johnson

Tulip's literal mirror image, brought to life by the train's chrome car.

  • Anti-Villain: She'll readily abandon Tulip in the Chrome Car, but only because she's desperate to live on her own.
  • Chrome Champion: Literally. When she's outside of the mirror world, she's as chrome as the car that gave her a voice.
  • Close-Call Haircut: When Tulip pulled her out into the real world, her hair was cut short thanks to the sander that would have erased her had Tulip been a second slower.
  • The Glasses Gotta Go: Along with Letting Her Hair Down, one of the first things that she does upon exiting the mirror world is take off her version of Tulip's glasses and crush them.
  • Heroic BSoD: The reflection cannot go wherever she's not reflected, so her attempts to leave the car result in a crippling incapability to do so and falling into depression as a result. Tulip gets around this by using the hand mirror in her Swiss Army knife to put the reflection inside of it, effectively cheating the "system" and allowing her to go anywhere by having the mirror reflect on itself.
  • I Choose to Stay: She decides to stick around in the car of living pencils rather than join Tulip because she wants to be her own person.
  • Letting Her Hair Down: One of the first things she does after switching sides with Tulip, differentiating herself from her prime self.
  • Mirror Self: She's Tulip's reflection given form.
  • Never Given a Name: Reflections like her don't have their own names, and she still hasn't come up with one by the time she parts with Tulip. Word of God later said that she named herself Gambit, after her favorite X-Men character.
  • What the Hell, Hero?: Gives one to Tulip about how she treats her loved ones.

    Khaki Bottoms 

Khaki Bottoms

Voiced by: Ron Funches

A living plush rabbit who resides in the Ball Pit Car.

  • Bunnies for Cuteness: He fits the bill.
  • Living Toys: He's made from plush.
  • Manchild: Considering how he resides in a Ball Pit Car.
  • Mundane Made Awesome: He makes a trip across the Ball Pit Car like it's some epic quest.
  • What Happened to the Mouse?: The Steward destroys the Ball Pit Car for the most part, and he's never seen again. That said, the Cat and One-One both survive the destruction, and since he's plush, he probably survived too.

    The Other Passengers 

Other Passengers

From what we saw from the Conductor's monitors, there are at least fourteen other people currently stuck on the train.

  • Badass Grandpa: Some of these are elderly, yet they're still surviving on the train.
  • Claimed by the Supernatural: Just like Tulip, they also have a number. Some as low as 10, but at least two of them have numbers above 99,999note .
  • The Ghost: Tulip never encounters any of them.
  • Hero of Another Story: All of them are passengers on the train with their own numbers and trials to go through.
  • Little Miss Badass: There's a little girl on board, and her number is down to 10.
  • Readings Are Off the Scale: The Conductor's monitors only show the bottom 5 digits, so those two passengers with numbers above 99,999? The numbers from the hundred-thousands slot and beyond are represented by "..."



I thought your game was cool when I played it. And you know how I feel about video games.

Tulip's best friend at home.

    Tulip's Parents 

Megan and Andy Olsen

Voiced by: Audrey Waslewski and Mark Fite

Tulip's recently divorced parents.

  • Amazingly Embarrassing Parents: Tulip certainly thinks so, to the point that sharing a memory about them makes her uncomfortable.
  • Amicable Exes: They're trying to be this, but they still get frustrated at each other. By the final episode, they seem to have finally found common ground.
  • Parents as People: They appear to be trying their best for the sake of their daughter, but they both have demanding jobs and communication can be an issue. Unfortunately, Tulip's needs such as needing a ride to coding camp end up lost in the shuffle and kickstarts the plot.
  • Passive-Aggressive Kombat: A number of their fights utilize this. They're outwardly polite but passive-aggressively digging into each other. Their fight at the water park being a primary example, with the issue of Tulip's eyesight being ammunition for an argument.
  • Small Role, Big Impact: Without the divorce and her father accidentally getting the schedule of the coding camp wrong, Tulip would never have boarded the Infinity Train.


    Spoiler Character 


Voiced by: Matthew Rhys

Alrick was the deceased husband of the Conductor, Amelia Hughes.

  • Adorkable
  • Alice Allusion: The first flashback in "The Past Car" showed him with a book report in regards to Alice in Wonderland. He himself was a blond-haired Cloudcuckoolander.
  • Childhood Friend Romance: He and Amelia have known each other since they were kids, which is probably what made his death even harder for Amelia.
  • Dark Is Not Evil: He wore a black hoodie just like the Conductor, but he was a really sweet person in life.
  • Hair of Gold, Heart of Gold: Had blond hair and was such a sweet person.
  • Happily Married: To Amelia.
  • In the Hood: He's shown to be wearing a hooded jacket.
  • Ironic Name: His Meaningful Name below, seeing as he's dead when the story begins.
  • The Lost Lenore: Amelia's grief over his death is why she boarded the train, and her inability to let him go is why her number is so unfathomably high.
  • Meaningful Name: His name is French for "old/noble ruler", which is probably a Red Herring to make people think that he was the Conductor and not his wife, Amelia.
  • Megane: Wore a pair of glasses.
  • Plot-Triggering Death: Had he not died, Amelia would have never gotten on the Infinity Train, and never tried to meddle with Tulip's quest and made everyone's life miserable.
  • Posthumous Character: He's only seen in flashbacks.
  • Red Herring: Is thought to be the Conductor due to him wearing a similar black hooded jacket and the flashback having him use a voice modulator that emulates the Conductor's robotic voice. It turns out that it's actually his wife emulating those quirks to keep his memory alive.
  • Riddle for the Ages: How did he die, exactly?
  • Satellite Character: His biggest contribution to the plot is that he is the catalyst for Amelia's descent as the Conductor.
  • Small Role, Big Impact: Only appears in a flashback in the penultimate episode, but it's his death that sparks Amelia's trip to the Infinity Train and subsequently becoming the Conductor.
  • Smart People Wear Glasses
  • Sweet Tooth: He loved jelly, and in the first flashback is eating out of an open jar of grape jelly on his desk. This explains the jelly on the road found in "The Unfinished Car".
  • Too Good for This Sinful Earth: So good that his wife was unable to move on and tried to make other passengers aboard the Infinity Train miserable if she couldn't get him back.
  • Walking Spoiler: This character's entire existence is the biggest spoiler of the series. How big? His existence ties to the Conductor's true character.


How well does it match the trope?
