In the fictional town of Chuggington are young novice railway anthropomorphic locomotives ('trainees') Koko, Wilson, Brewster, Hoot, Toot and Piper. The trainees learn the value of loyal friendship, telling the truth, listening carefully, persisting under adversity, completing tasks, resolving conflict without violence, and similar values. The locomotives, called “Chuggers”, are intelligent, empathetic, independent and somewhat self-directed. They have mobile facial and body features. Chuggers have no crews (yet some have opening crew doors). Chuggers regularly interact with other humans such as passengers and maintenance crews.
The town of Chuggington has a central area of large modern buildings. Side-by-side railway tunnels coloured red, blue, yellow, green under the town centre lead to the outside world. Countryside settings include a farm, a safari park, and a quarry. A ‘Chugston Hotel’ is mentioned. “Old Chuggington”, an abandoned old town overgrown with wild vegetation, is visited. The background and scenery are also computer-generated. There are turning-camera and moving-camera shots.
The creative core behind Chuggington is Sarah Ball, a producer and director who worked on Bob the Builder, and Don Toht, who designed the characters and sets. Substantial parts of the animation are done in Shanghai, China by Motion Magic.
As well as the regular ten minute episodes, Chuggington: Badge Quest, there are four minute shows, focusing on the trainees efforts to earn reward badges for their "Chugger" training.
Three Chuggington specials were commissioned for release on DVD from 2013 onwards.
The first series of 52 episodes was sold to broadcasters including the BBC, ABC (Australia), TF1 (France) and Super RTL (Germany) in a deal announced in February 2008. A second series of 26 episodes was purchased by the BBC and many other broadcasters throughout the world. Aimed at children between the ages of 3 and 6, Chuggington made its UK debut as a "soft launch" on BBC Two on 22 September 2008.
Brewster, Koko, and Wilson are the main characters in Chuggington.
- Wilson, (voiced by Morgan Overton in the UK Series 1, 2 and 3, Edward Sharpe In the UK in Series 4 and Tony Terraciano in the US), is a lively red engine based upon an EMD F-unit. His enthusiasm is opposed by his short attention span, and most of his adventures are in Chug Patrol.
- Brewster (voiced by Charlie George in the UK in Series 1, 2 and 3, Toby Davies in the UK in Series 4 and Miles J Harvey in the US) is a strong diesel-electric locomotive built for heavy loads. He is British Rail blue with yellow face; Brewster is similar to a BR Deltic diesel engine, but with a single end-cab. He is a member of the Chuggineers, the building team on Chuggington. He likes to haul heavy loads on pick-ups, and often picks up too much load. Other Chuggers may rush when given a task, but Brewster asks questions if he is unsure. He is dependable, respectful and can be relied on when there is trouble.
- Koko (voiced by Imogen Bailey in the U.K Series 1 and 2, and Brigid Harrington in the U.S. Series 1 and 2), is an electric engine, modelled on the bullet train. She is green and purple, and was built for high speed, being one of the fastest Chuggers in Chuggington. She loves to explore and have adventures, and to challenge her friends to a dare or a race. Although she can get into mischief, she always means well and knows when to apologise.
- Hoot and Toot are twins. They are nearly always seen joined back-to-back, but in at least two episodes by strong pulling they manage to separate. Toot is green, female and has blue eyes; Hoot is blue, male and has green eyes – he is also red-green colourblind.
- Piper is a small oil-fired steam locomotive. In her first episode, Old Puffer Pete says that she runs on vegetable oil. In another episode we find out that Piper can be mischievous. Though she means well, she is very inexperienced and won't often take time to think, but realizes her mistakes and does well in the end.
