Gordon is an express engine who works on the Main Line. He is Flying Scotsman's only surviving brother. Gordon is also one of the fastest and strongest engines on the Island of Sodor, whose main task is to pull the Wild Nor' Wester, the railway's express train.[4] At times, this leads him to feel superior. Gordon is mainly used for passenger duties, but has occasionally pulled goods trains, to his chagrin.. He is also known to haul special services such as royal trains.
