Duck (voiced by Steven Kynman in the UK and US) is a Great Western tank engine who runs his own branch line with Oliver, and is numbered 8.After it closed, he was bought by the Fat Controller and now works on both Thomas' Branch Line, with his coach Henrietta.

His line would later be reopened as part of the North Western Railway, with Toby being reallocated to his old shed. Toby originally worked on a tramway between Lower Arlesburgh and Arlesdade End to Ffarquhar Quarry. Toby (voiced by Ben Small and Rob Rackstraw in the UK and William Hope in the US) is a brown square tram engine who used to work on his own railway near Thomas' Branch Line, and is numbered 7.His favourite job is to deliver the mail and he works on Thomas' Branch Line as a goods engine. He is Thomas' best friend and one of the junior engines on the North Western Railway, often getting into trouble when he tries to play tricks on the other engines. Percy (voiced by Keith Wickham and Nigel Pilkington in the UK and Martin Sherman and Christopher Ragland in the US) is a little green saddle tank engine who was brought to Sodor to help run the railway during Henry, Gordon, and James' strike, and is numbered 6.Despite being a mixed-traffic engine, he does not like pulling trucks, and feels superior to the others except the big engines. He is proud of his splendid red paintwork, but tends to be vain, boastful and overconfident, and does not like getting dirty. James (voiced by Keith Wickham and Rob Rackstraw in the UK and Kerry Shale and Rob Rackstraw in the US) is a red mixed-traffic tender engine who works on the North Western Railway, usually on the Main Line, and is numbered 5.

He's mainly used for passenger duties but has occasionally pulled goods trains, much to his disliking, as he believes that these are below him. At times, this leads him to feel superior. He is one of the fastest and strongest engines on Sodor and his main task is to pull the railway's express train. Gordon (voiced by Keith Wickham in the UK and Kerry Shale in the US) is a big blue tender engine who works on the Main Line, and is numbered 4.Henry moved from Tidmouth Sheds to Vicarstown Sheds in order to be closer to his work. Following an accident while pulling the Flying Kipper, Henry was rebuilt, giving him a new shape and greater reliability, eliminating the need for the expensive special coal. He was originally a prototype engine that needed special Welsh coal to operate properly.
