Billy (tryphlan)

Thomas is a tank engine who lives at the big station on the Island of Sodor. He's a cheeky little engine with six small wheels, a short stumpy funnel, a short stumpy boiler and a short stumpy dome. He's a fussy little engine, too, always pulling coaches about, ready for the big engines to take on long journeys. And when trains come in, he pulls the empty coaches away so that the big engines can go on rest.
