A diesel who was sent to Sodor to help the engines, but insults them by saying they were out of date. He gets his comeuppance as he breaks down by getting an inspector's bowler hat caught in his air intake. The Diesel crept away and leaves behind "a rather nasty smell and a battered bowler hat".

- Enemy Mine: In the magazine story, "The Big Hero", he has to work with Bill and Ben in the China Clay Pits, as they and the Horrid Lorries are competing for the China Clay contract.

Smudger
- "Listen, Dookie! Who worries about a few spills?"Basis: Fletcher Jennings Class Bb "Dolgoch"Number: Mid-Sodor Railway 2Built: 1893
A tank engine from Duke's story. He was a showoff who often derailed himself and never listened to Duke. He was converted into a steam generator and never heard from again.
- Adaptation Name Change: He replaced Stanley (No, not the engine introduced in The Great Discovery) from The Railway Series in the television series, having suffered the same fate as him.
- And I Must Scream: His fate. He is made into a generator, immobilizing him forever. Eventually, the Mid-Sodor Railway was buried by grass and mud. It's very likely that he's still there, unable to call for help.
- Asshole Victim: His Jerkass behavior is what caused him to get turned into a generator. Although, considering that the railway was buried, one might feel sorry for him in that regard.
- Chuck Cunningham Syndrome: He hasn't been seen since season 4. And because the Mid-Sodor Railway is closed down, it's unlikely he will ever return.
- Drives Like Crazy: Rode rough and often came off the rails.
- Green and Mean: Has green livery and is a total asshole.
- Identical Stranger: He's the same prototype as Rheneas, introduced several episodes later (indeed, he's literally the same model, which is why the inside of his cab is still red).

- Smug Smiler: His default facial expression is a haughty smile.
- What Happened to the Mouse?:
- He's last seen as a steam generator. Afterwards, the railway gets shut down, Stuart and Falcon leave, Duke is locked in his shed, and the railway becomes overgrown with a forest...and Smudger's fate is never mentioned.
- Oddly, Japanese promotional material depicts him having been moved to the Skarloey Railway, still as a generator.

- Establishing Character Moment: In his debut episode, Harvey uses his crane to put back Percy and the trucks on the rails from the road.
- "Eureka!" Moment: In "Gone Fishing", Bill and Ben's teasing words on how he should be going fishing gives Harvey the idea of picking up the derailed flatbeds he's pulling with his crane.
- The Klutz: He has spun his crane so fast, he actually destroyed two crates! The first time he does this is "Stuck in Gear", where he sends a crate flying and the second time he does this is "What Rebecca Does" This trope is downplayed the second time since he didn't throw the crate as high, but he spins his crane and manages to throw another crate. After those episodes, this trope later becomes subverted.

- Mighty Glacier: Because of his weight, he can't reach or handle high speeds.

- Red Is Heroic: Harvey has red paint, and he often saves the day by rescuing engines.
- Scotland: Has a Scottish accent as of the CGI Series, as his prototype was built in Glasgow, Scotland.

A powerful bright-yellow tender engine. After being teased by Emily on pulling empty trucks, she feels less important, but with the help of Thomas, she realizes that pulling empties is important than she thought.
- Chuck Cunningham Syndrome: Molly has not been seen after the end of the model era.
- Cool Big Sis: Molly's official bio describes her as being level-headed and sensible, with a peacekeeper attitude, often acting as a big sister to the other engines. Due to her small amount of appearances, this hasn't been seen in the actual show.
- Demoted to Extra: Has made cameos after her debut episodes.
- I Just Want to Be Special: Her goal in her debut episode is to do something other than pulling empties.
- Informed Attribute: Molly is described as being a Cool Big Sis, but this isn't really shown in the series.
- Jerkass Ball: In "Emily's Rubbish", she hung out with Murdoch and Neville and they all bullied Emily for working with Whiff. All three of them are usually pretty friendly engines. Molly, in particular, was actually teased by Emily herself, so this could be seen as revenge for what happened in "Molly's Special Special".
- Light Is Good: Molly has bright yellow paint and is a friendly engine.
- Nice Girl: Molly is usually kind-hearted, peace-keeping, and sensitive.
- Prone to Tears: She's easily sensitive when it comes to being made fun of. She's also easily embarrassed by conflict and runs away from it and according to her bio.
Neville
- Basis: SR Class Q1 No.33010Built: 1942Number: 33010
Neville is a black engine with an unusual square shape. Rumors were spread about him that he was friends with the diesels, but this was later proven to be false and Neville became friends with the Steam Team after Thomas rescued him.
- All of the Other Reindeer: Neville was ostracized by the engines because they thought that he was friends with the diesels, when in actuality, the diesels were being mean to Neville.

- Category Traitor: The engines see Neville as this, accusing him of being friends with 'Arry and Bert who were mocking him.

- Dark Is Not Evil: Neville has dark paint, a square shape that makes him resemble a diesel, and is supposedly shown to be friends with the diesels in his debut episode. However, he wasn't actually hanging out the diesels, and Neville is actually a nice engine.
- Flat Character: Neville doesn't have much personality to him other than being friendly and somewhat sensitive. This isn't helped by his limited number of appearances.
- Jerkass Ball: In "Emily's Rubbish", he hung out with Murdoch and Molly and they all bullied Emily for working with Whiff. All three of them are usually pretty friendly engines. Neville's case is particularly odd considering he himself was bullied in his debut episode. It could also be revenge for Emily being rude to him in his debut episode.
- Nice Guy: He's usually gentlemanly and friendly. He also easily forgave Thomas for spreading rumors about him in "Thomas and the New Engine".
- Not So Above It All: He may be a kindhearted engine, but, as noted above, he teased Emily for working with Whiff.
- Prone to Tears: He can easily be hurt by unkind comments.

- Chest Insignia: Her repaint in Season 21 adds "NWR" lettering, making her the first engine with the lettering in the TV series, with Rebecca later joining her.

- Eagleland: A mix of Beautiful and Boorish; though gets Beautiful later on.
- Expy: Hmm, Genki Girl, Pink Girl, Blue Boy, frequently annoys the hero despite good intentions, where have we heard that before? It helps that her name bears similarities to Amy's original name, Rosy the Rascal and the fact that she was given a cherry red coat in season 21.
- The Friends Who Never Hang: In season 22, Henry starts sleeping with her at Vicarstown, despite the two never interacting previously.

- Rose-Haired Sweetie: In this case, "Rose Painted Sweetie". Before her new red livery, she was lavender and is sweet and cheerful.
- Savvy Guy, Energetic Girl: The Energetic Girl to Thomas' Savvy Guy. Rosie is enthusiastic and bubbly, which contrasts with Thomas' more level-headed demeanor.
- Shout-Out: 37, the number she gains in her Significant Wardrobe Shift to a new cherry red livery, references her being the 37th standard gauge engine introduced in the series.
- Significant Wardrobe Shift: She takes on a new cherry red livery in season 21 and Journey Beyond Sodor.
- Stalker with a Crush: Rosie was this to Thomas at first, constantly following him around and trying to mimic his every move. This eventually was phased out, though.
- Tomboy: She's feisty, energetic, and loves taking on hard jobs. This is more noticeable when she gained a cherry red livery and her lip-gloss, blush, and stereotypically pink livery were ditched.
- Tomboy and Girly Girl: The Tomboy to Emily's girly girl.
- Unwitting Instigator of Doom: Her changing her livery to red was indirectly the cause why Edward (and later Henry) left Tidmouth Sheds, as James became jealous of her, which causes him to crash into the back of the sheds that some of the engines had move out until it was repaired.
- What Kind of Lame Power Is Heart, Anyway?: Rosie isn't strong enough to pull heavy loads, but is really good for pulling trucks full of balloons.
- Youthful Freckles: She has some freckles on her face.

A silver tank engine who debuted in The Great Discovery, who works as a combination of a shunting engine and a mixed-traffic engine. Stanley was sent to Sodor to do Thomas' workload during the restoration of Great Waterton. Due to his popularity with the other engines, Thomas grew jealous of him and plans to make him look weak. This would cause Great Waterton tower to be demolished and causes Thomas' friends to turn against him. After Thomas is gone missing, Stanley was the first to realize Thomas' feelings and was the one who found and rescued him. Both became friends and with a combined effort made it back to Great Waterton in time to prepare for the opening celebrations.
- The Ace: The narration describes Stanley as newer, bigger, and stronger than Thomas...at least, from Thomas' point of view, hence why the latter quickly grew jealous.

A tank engine who loves to tell jokes and have fun. He works as a shunter in Knapford yards.
- A Day in the Limelight: In "Not Now, Charlie!".
- All Work vs. All Play: The All Play to Edward's All Work. Charlie keeps convincing hardworking and serious Edward to skip duties to have fun in "Charlie and Eddie".
- Ascended Extra: Charlie had his roles greatly expanded upon since Andrew Brenner took over as head writer. This hasn't lasted long, however.
- Cassandra Truth: An unfortunate downside to his jokey nature is that engines have a hard time believing him when he's being serious. This is shown in "Not Now, Charlie!".
- Character Development: In "Not Now, Charlie!", he is fleshed out a lot more and the episode nicely deconstructs his jokey nature. In the Brenner era, Charlie is kinder and doesn't try to pressure the other engines into shirking their responsibilities.
- Cloudcuckoolander: Charlie is quite strange and silly.
- Composite Character: For Billy. Billy was going to appear in "Splish, Splash, Splosh!", but was cut. Charlie replaced him. This makes sense because they're the same prototype and they both love fun.
- Crying Wolf: Made a few jokes about elephants with his friends. Then when he finds a real elephant stranded on the line, his warnings fall on deaf ears.
- Demoted to Extra: After season 18, he was relegated to background cameos and hasn't had a speaking role since then.
- Friend to All Children: Charlie loves spending time with children and is well-liked by them because of his funny jokes and playful nature. He is also popular at parties.
- Fun Personified: Charlie has a reputation for being a really fun engine. He loves playing games and telling jokes.
- The Hedonist: Is described as 'the most fun engine' and seeking fun and games from the other engines in the form of racing, jokes, and shirking their responsibilities. This was averted in Season 17, where Charlie mainly tells his jokes during the off periods in between his and his fellow engines' work instead of doing it whenever he pleases.
- Identical Stranger: He and Billy (season 11) are the exact same prototype.
- Ignored Epiphany: At the end of "Not Now, Charlie!", after the communication problems it causes, Charlie decides to stop telling jokes. This of course, doesn't last very long.
- Jerkass Ball: In "Ho Ho Snowman", where he disguises himself as a snowman and keeps forcing Henry to like snow, when all he does is scare him. He also grabs it in "Race to the Rescue", where he teases Flynn's road wheels.
- Laughing at Your Own Jokes: Charlie does this a lot.
- Not Now, Kiddo: Gets subject to this in "Not Now, Charlie!", where nobody listens to him about the elephant.
- Odd Friendship: With Edward in "Charlie and Eddie".
- Parental Favoritism: While the engines don't have parents, their controllers act as parental figures to them. Charlie's controller on the Mainland considers him his favorite engine.
- Phrase Catcher: In "Not Now, Charlie!" - "Not now, Charlie!".
- Plucky Comic Relief: Charlie is lively, cheerful, and tells jokes while working.
- Pungeon Master: A lot of Charlie's jokes are puns. For example:Charlie: Why are pirates called pirates? Because they arrrr!
- Simpleton Voice: He speaks in this voice in the US dub, despite him not being unintelligent.
Winston
- Voiced by: Matt WilkinsonBasis: Type 4B Wickham Trolley
A red inspection vehicle, Winston looks like a convertible on rails. He's used by The Fat Controller for inspecting line conditions.
- Butt-Monkey: Winston is this, due to constantly being subject to The Fat Controller's terrible driving skills.
- Cars Without Tires Are Trains: Winston essentially resembles a convertible without tires, and is used for rail travel.
- Character Catchphrase: "Early days, sir. Early days".
- A Day in the Limelight: Wayward Winston.
- Demoted to Extra: Went from being a major character in season 17 to getting one cameo in season 18.
- Did You Just Punch Out Cthulhu?: One of the few characters to stand up to the Fat Controller. He forgets to put on Winston's brake, causing Winston to roll away unmanned. The Fat Controller scolds him after, but Winston calls him out on it.
- Drives Like Crazy:
- Though it's not his fault. The Fat Controller simply can't handle him properly. When one of his assistants drives him in Happy Birthday, Sir!, he drives perfectly fine.
- On the other hand in said episode, he tends to leave said driver in a bind by constantly heading back and forth searching for a present for the Fat Controller (eventually biffing into Thomas).
- Nice Guy: Winston is tolerant, considerate, and patient.
- The Quiet One: In the later episodes, Winston doesn't really say much. In fact, he hasn't spoken since "Santa's Little Engine".
- Runaway Train: Well, more like "Runaway Rail Car", but he is subject to this in "Wayward Winston".
- Undying Loyalty: To the Fat Controller. He is very loyal to him and always puts up with his driving skills.
Stafford
- Voiced by: Keith WickhamBasis: NSR battery-electric No.1Number: 1917Built: 1917
Stafford is an electric shunting engine introduced in season 16. He often works in Knapford Yards.
- A Day in the Limelight: In "Steamie Stafford".
- Be Yourself: He learns this in "Steamie Stafford".
- Butt-Monkey: In his debut episode, "Welcome, Stafford!", he is this due to him constantly having to stop to recharge his battery, and due to Spencer trying to outshine him.
- Demoted to Extra: After season 17, he was demoted to background appearances and seldom has speaking roles.
- Extreme Doormat: In "Welcome, Stafford!", where he constantly lets Spencer walk (roll?) all over him and try to overshadow him.
- Green-Eyed Monster: In "Steamie Stafford", he was jealous of the steam engines because they could make noises and he couldn't.
- Nice Guy: Stafford is humble, courteous, and friendly to everyone he meets.
- The Quiet One: Being an electric engine, he cannot make noises like the steam or diesel engines. He actually becomes this trope after season 17 due to him having limited speaking roles.
- Saying Sound Effects Out Loud: Stafford does this in "Steamie Stafford" while trying to be a steam engine.
Philip
- "Hello there! My name's Philip! I'm a diesel boxcab!"Voiced by: Rasmus HardikerBasis: modified PRR Class A6Number: 68Built: c.1930
A cheeky young diesel-electric switcher that often works as a station pilot. Philip is energetic and very talkative, much to the amusement of the younger engines, but the annoyance of the bigger ones.
- Big Brother Worship: Becomes very fond of Toby at one point due to their similar boxcab design. Naturally, this only leads to exasperation for poor Toby.
- Bully Hunter: In "Apology Impossible", he stands up to James who kept harassing him.
- Cartoon Creature: While primarily based on a PRR A6, his back end is based off the prototype AGEIR (Alco, General-Electric and Ingersoll-Rand) boxcab #8835, but with five windows instead of seven. He also has UK-standard buffers and loose couplings in order to fit in.
- Character Development: Philip receives some in "Apology Impossible" when he becomes assertive and stands up to James.
- Cheerful Child: Philip is one of the younger, smaller engines on the Island, and is full of energy and enthusiasm.
- Class Clown: Although he's not in a class, Philip's character bio describes him as one.
- Comically Missing the Point: Philip believes he beat Gordon in the race in "The Little Engine Who Raced Ahead", despite that Gordon doesn't want to race him.
- Genki Guy: Energetic and eager.
- Intergenerational Friendship: He is friends with (and later starts living with) Edward.
- Keet: Very excitable. Tends to irritate Gordon and James as a result.
- Motor Mouth: He loves making conversation.
- Older Than They Look: Philip was built in 1930 (he is technically 90 as of 2020), but he looks and acts like a kid.
- Replacement Flat Character: His naive and childish (and somewhat cheeky) attitude very much replicates how Thomas and Percy were initially, who by now act as Cool Big Bros to Phillip. However, he eventually gets Character Development.
- Small Name, Big Ego: Philip is very overconfident in his abilities and loves to boast about his accomplishments, especially about the time he "beat" Gordon in a race. Even James, of all people, thought he was a showoff.
- The Thing That Would Not Leave: To Gordon. He even makes a habit of sleeping in Tidmouth Sheds, to his dismay.
