"I've never driven an ATV before!"
-Thomas to Ivo Hugh
Thomas was a tank engine who worked on the Ffarquhar Branch line.
Connor recruited Thomas to assist him in finding 089. Thomas didn't do too much, as he had his branchline to attend to most of the time, but he did however use the Road-Rail Transporter in an effort to find the Portal, but this didn't work out well.
Thomas assisted Ivo Hugh in assulting the Vicarstown Dieselworks where Diesel was arming his forces, but was injured in the process. Later Thomas and the others arrived on Tankopia via the Portal and stayed nearby it to gaurd a railway yard. The efforts were futile as Thomas was captured, but he was later saved by Scruff and Gold Leader. Thomas and the others later arrived on the Mainland and spied on D199 as he gave a speech. When the latter left, 089 explained that they needed to eliminate him. Thomas stayed with Connor after he was hurt, participated in a final battle, and attended Den's funeral.
Thomas informed 089 and Lady of the events that transpired during their decade-long absence. The following day Thomas began helping Officer Brown in his efforts for tracking down the assassin. Thomas also attended a meeting at Knapford Station. He then assisted General Phoenix Brown in spying on and attackng Professor's Gang. Later, Thomas was ambushed and killed by Professor's Gang during one of his mail runs.
