Bill and Ben (voiced by Shaun Fleming) are characters from Thomas the Tank Engine and Friends. They are twin tank engines who work for the Sodor China Clay Company. They are young and cheeky, and love playing jokes on the big engines, but are kept in order by Edward the Blue Engine and BoCo the diesel. Apart from their nameplates, they are absolutely identical- which can be confusing to engines who don't know them well. They work in the china clay quarry and at Brendam Docks, where they are kept busy shunting trucks. The Fat Controller sometimes allows them to carry out special jobs, like taking BoCo's heavy goods train and running 'Brake Van Specials' for visitors, who often come to the quarries especially to see the twins.
