Thomas is a cheeky blue engine that works on the North Western Railway
Details of Thomas' arrival on the North Western Railway in 1915 by mistake. No one knows how it happened, but some say that it happened because of a confusion. However, it is that he was sent to Sodor in a wartime mix-up. His driver and fireman got along well with the local people and married Sudrian women. By 1920, neither one wanted to leave the Island or their beloved engine.
During an inquiry, Sir Topham Hatt found out that the LB&SCR had written off Thomas as being "lost on war service". Rather than face complications resulting from a change in their books, the LB&SCR quietly sold Thomas to the North Western Railway for a "nominal sum".
Thomas formerly worked as the station pilot at Vicarstown, shunting trains for the bigger engines on the Main Line to take out. He enjoyed teasing the other engines, especially Gordon, who he would quietly sneak up on and whistle loudly while Gordon dozed in a siding. Eventually, Gordon managed to get back at Thomas by pulling out of the station before he could be uncoupled from his coaches, dragging him down the line at a tremendous speed. Thomas vowed to never tease Gordon again. Perhaps as a result of his brief excursion beyond his boundaries, Thomas longed to see more of the world and become a part of it and became jealous of the bigger engines for having the chance to pull trains.
Thomas is a rather cheeky, but kind engine, and generally behaves well. Despite his somewhat young age, he serves as a good mentor for engines like when he taught Edward how to manage trucks. He loves teasing the others, but can become irritable when they tease him. If he is ever talked down to by a bigger engine being boastful, like Gordon. He isn't shy of talking back. He can also have a slight tendency to rush into a situation regardless of the danger
Thomas is based on the LB&SCR Class E2 0-6-0T, particularly the second batch of locomotives built with extended side-tanks. These engines were built by Brighton Works between 1913-1916 to replace the ageing Stroudley E1 class and were primarily used for heavy shunting and short-distance goods trains in the London area and on the south coast. During their final working years, the E2 class worked as shunting engines at Southampton Docks alongside the USATC S100 Tank Engines (Rosie's basis), until they were replaced by the BR Class 07 diesel shunters (Salty's basis). All of the E2s were scrapped, with none surviving into preservation. Thomas has several major differences from the original E2 class. He is much shorter in length than his original basis, he has two extra windows on the sides of his cab and he has wheel splashers, something the original E2 class lacked.
Thomas is painted in NWR bright blue with red lining. His number is painted on the sides of his tanks in yellow with red lining and the lining around his cab windows is yellow.
