->''"Chuggington... Chugga, chugga, chugga, chugga, Chuggington! Chuggington... chugga, chugga, chugga... chugga, chugga, chugga..."''

''Chuggington'' started airing in Great Britain in 2008, and debuted on the Creator/DisneyChannel in the United States in 2010. It features three young, talking trains referred to as "trainees", and several supporting characters in the form of either people who work at the station or other anthropomorphic trains. Most episodes revolve around these three learning a new kind of job, including pulling passenger cars or delivering cargo... also, serving ice cream and learning to be superheroes.

Two of the founders of the company that produces this show were previously executives for the company that produces ''WesternAnimation/ThomasTheTankEngine''. [[SarcasmMode Not that there's any similarity between this show and that one.]]

The main characters are as follows:
* '''Wilson''', a red train who likes to have fun, often at the expense of listening to important directions. He has also been shown to be impatient and impulsive. Presumably used as a way of demonstrating to kids the benefit of taking your time with important jobs and listening carefully.
* '''Brewster''', a blue train that is supposed to be the strongest of the three, but also has a tendency to be overly cautious. He's not used to demonstrate subtle moral lessons so much as the two others, but is the butt of their jokes more often.
* '''Koko''', a green train who is the fastest of the group, and is quite competitive as well. She tends to work faster than the others, then teases them about being slow. This often results in things not going well, or taking longer than normal. The resulting {{Aesop}} is similar to what is taught via Wilson.
!!''Chuggington'' provides examples of:
* AbridgedSeries: ''Chuggington: Little Trainees,'' four-minute re-edited episodes with a narrator a la Thomas, produced following the fifth season completed production.
* AccidentalMisnaming: Being old and forgetful, Puffer Pete does this regularly with everyone's names.
* AllCGICartoon
* AlternativeForeignThemeSong: The Japanese version had an exclusive ending theme that included a dance number, called [[https://www.youtube.com/watch?v=kRzWPlkfN0U "Janken Train"]] (Rock-Paper-Scissors Train).
* AmbiguouslyGay: Chatsworth and Harrison, ''in spades''.
* AttentionDeficitOohShiny: Wilson.
* CatchPhrase: There are several. Like with ''WesternAnimation/ThomasTheTankEngine'', many of them are [[FlintstoneTheming railway-themed puns]]:
** Wilson:
*** "Let's ride the rails!"
*** "Perfecto!"
** Koko:
*** "Chugga-chugga choo-choo!"
*** "Traintastic!"
*** "Go Koko! Go Koko!"
*** She also lets out a squeaky "Ooooooh!" when she is excited.
** Action Chugger: "I'm number one! I'm helpful, I'm strong, I get the job done!"
** Emery: "This chugger is ready to depart." (See also VerbalTic below.)
** Calley: "''[[MadLibsCatchphrase [insert current task here]]]'' chugger coming through-oo!"
*** e.g. "Snowplough chugger coming through-oo!" Koko [[BorrowedCatchphrase used this catchphrase]] in one of the Badge Quests.
* ChaosArchitecture: Mainly between Seasons 3 and 4. Notably the Repair Shed being moved to make space for the Chug Patrol HQ and many human-catering features being removed and replaced with cargo drop-offs.
* CryingWolf: Zephie, a small anthropomorphic trolley, is outfitted with a siren to be used in case of emergency in one episode. She almost immediately starts coming up with excuses to use it.
* TheKiddieRide: A carousel made by ''Kiddie Rides Australia''
* {{Leitmotif}}: Action Chugger has one that can be heard whenever he shows up on the scene.
* LoadsAndLoadsOfCharacters: Despite the fact that this show is relatively new, there's already a substantial cast of supporting characters. There are at least a dozen other trains besides the three trainees, about half a dozen recurring human characters, and a few other humans who were only featured in one episode.
* LostVoicePlot: In one episode, Old Puffer Pete loses his voice and the others try to get it back and find out why he lost it. [[spoiler: It turns out his mouth needed oiling.]]
* MeritBadgesForEverything: Badge Quest!
* SentientVehicle
* [[SinglePowerSuperheroes Single Power Superhero]]: Action Chugger, a train that can fly, and... that's all.
* SpotlightStealingSquad: Hoot and Toot in the second season.
* SteamNeverDies: Steam locomotives will go on and on and on. Forever. Though one of the newest episodes introduces one that runs on vegetable oil, and the characters comment on the eco-friendliness of this.
* ThemeTuneCameo: When Vee sounds an announcement, the three-note tune is the same sound as the "Chuggington" heard in the theme tune. Brewster can be heard briefly humming the theme tune during one of his Badge Quests.
* VerbalTic: Being a public transit chugger, Emery has a habit of saying certain phrases as transit announcements.
* TheVoice: [[MeaningfulName Vee]], the depot announcer and dispatcher. She is only ever "seen" via her omnipresent public address system, which is capable of showing body language (well, as much as a [[TheFaceless faceless]] speaker post fastened to the ground can anyway). This coupled with contradictory clues from various episodes make it unclear if she is a [[AmbiguousRobots human or an intelligent machine]] like the chuggers.
