Nightmare Fuel / Infinity Train

Go To
"This isn't right!..."

Infinite possibilities can also mean infinite scares.

As a Moments subpage, all spoilers are unmarked as per policy. You Have Been Warned.

  • The SDCC 2018 trailer is pretty spooky, in no small part from how Tulip's mom keeps calling for her daughter, not knowing that she's vanished without a trace. The slow turn of Tulip's hand to see the glowing numbers is also agonizing to watch.
  • According to Word of God, the show's aesthetic is similar to, of all things, The Mysterious Stranger segment of The Adventures of Mark Twain. Not to mention, listen closely at 4:23 in the Mysterious Stranger clip that Owen linked to. Sound familiar? The Infinity Train jingle is based on it. A jingle that plays when clay people given life by Satan fall to their deaths is the Infinity Train theme. (Granted a very close listen reveals the tune does play in the background a bit when the gang first enters Satan's world, but it's barely noticeable—the above moment is where it's much more prominent.)
    • To quote a commenter:
    Jayden Yamada: If you are looking for the cue, passengers, it is at 4:23. Now is when you panic.


Season 1

The Grid Car
  • The first episode gives us some idea of how far this show is willing to go as Tulip, in her attempt to escape the train, finds herself the target of vicious, relentless, giant lifeforce-draining cockroach monsters. No punches are pulled; Tulip's face is shown visibly aging as her vitality is drained from her.
  • Tulip catches a glimpse of someone getting dragged off the train and reduced to particles by some kind of vortex. It scares her so much that she wants to leave immediately.
    • This gets lightened up a bit in the last episodes, as the vortex is the way home.
  • One which only becomes obvious in retrospect: look very closely at the trees in the background as Tulip wakes up in the snow car. Notice anyone familiar? Yeah, turns out the Conductor was right there the entire time.

The Cat's Car

  • The trip through Tulip's memories is a degenerating cavalcade of Uncanny Valley that initially ranges from funny, harmless changes to subtle, eerie differences, and quickly drops from there.
    • One memory involves Tulip going downstairs late at night and kneeling by the couch, staring and smiling at seemingly nothing. As Tulip looks at her past self, she realizes there's some weird, muffled talking coming from seemingly nowhere, before the memory suddenly "glitches." It's revealed later that this was simply an altered memory of Tulip speaking with her dad, but without context it's very unsettling, especially for the brief moment where past Tulip is replaced with something under a blanket lying on the couch.

    • The memory at Tulip's birthday party suddenly cuts to a close up of Tulip's mother with a terrifying Slasher Smile, before turning to her with the Steward's face, her father lunging at her while stretching into terrifying, Cronenbergian proportions, and Tulip is consumed by static at the end.
    • The next particularly distorted memory has Tulip's warped memory of her parents' divorce, as the entire room bursts aflame and Tulip's parents converge on a crying Tulip while changing into horrible, demonic creatures, chanting "DIVORCE! DIVORCE!"
  • The ending, where it turns out The Cat is being threatened into trying to capture Tulip by the Steward and a shadowy figure implied to be the mysterious "Conductor". Whoever it is, all we see of them is a monitor with an ominous line on it that moves in time with the bizarre mechanical "voice" it uses to give orders to the Steward.

The Unfinished Car

  • One-One's obsession with "fixing" the glitchy-looking town full of talking turtles takes an unsettling turn near the end, when both Glad-One and Sad-One start to Speak in Unison, something they have never done up until this point.
    • Fridge Horror kicks in when you realize that the only time the two halves of One-One agree with each other is in their neuroses.
    • Take a look back at the Mysterious Stranger clip. What else speaks with two voices?
    The Mysterious Stranger: "I can do no wrong... for I do not know what it is."
    One-One: "I'm here to get things back in order."

The Chrome Car

  • We learn that reflections are intelligent beings, distinct from the person that they mirror, and if they step out of line they get ground into dust.
    • The reflection authorities seem totally affable at first - and then reveal their intent to kill Tulip's reflection for acting out of line. Suddenly the pair of Good Cop/Bad Cop buddies put some seriously Uncanny Valley masks on, and pull out an arm-mounted sander that might as well be a chainsaw by reflection standards. The worst part is that they imply this has happened before, likely with previous passengers, and one of the officers is The Unfettered in getting the job done.
  • Mirror Tulip has a reflection...

The Ball Pit Car

  • Watching the episode closely, you can see the Steward is lurking in the background from the moment they stepped into the car.
  • You know a situation is pretty terrifying if One-One looks like he's so scared he can barely move without Tulip yelling at him to run away.
  • Though it failed to kill her, the Conductor intimidates Mulgrowl into chasing after One-One - before signaling the order for the Steward to fire on the tube The Cat should've been inside. Just before this, the Steward was also violently firing upon Tulip, demonstrating that the Conductor has no qualms about receiving her dead rather than alive.
  • We finally get a full glimpse of The Conductor, and they prove just how ruthless they can be by threatening Tulip and her friends (in the process giving Tulip a Breaking Speech about how her friends were imperiled by her stubborn insistence on investigating the train), and turning Atticus into a Ghom. This implies that all the Ghoms in the wilderness we saw in "The Grid Car" were former passengers who got on the Conductor's bad side.
    • The creator revealed that not all Ghoms were created this way. Still, makes you wonder...

The Past Car

  • We find that in the tape, Amelia was running towards her college and was on the highest part building wearing a dark hood. Given that we find out her husband Aldrick had passed away, she was avoiding going to his funeral, too distraught to live in a world without her husband. The train appearing right in front of her at this moment could have been an Interrupted Suicide.

The Engine

  • While we know there are obviously more humans on board, the fact that they range from children much younger than Tulip to the elderly is kind of horrifying, especially with some of these passengers having numbers that stretch beyond the tens of thousands.
  • Amelia's spent so long trying to recreate her old life instead of overcoming her issues that her number stretches off of her hand, around her arm, and wraps around her neck creating a number with a lot of digits! Considering that the only way to leave the train is to get the number to zero... yeah, even she acknowledges that her ever returning to Earth is an impossibility at this point.
    • To give a comparison, Tulip only started off at 115. Some passengers on the train have numbers past five digits, which the computer doesn't bother counting. It appears that Amelia's repeated failures to recreate her life with Aldrick have caused her mental state to spiral so far that she may never recover.
  • How long Tulip has been on the train. Time doesn't run differently there and the Conductor says that she had been on there for months thwarting their plans, with the flash forward at the end revealing that Tulip was there for at least five months. Her parents were most likely devastated and worried sick over her sudden disappearance. Meanwhile, Amelia has been on the train for years and will likely grow old there and die, and that’s not even getting into the stays of other passengers (past, present, and future)...
  • Even though Tulip's returned to the real world, she no longer has a reflection which is likely to remind her of the events she went through when on the train forever.


How well does it match the trope?
