Oliver is the number 11 Great Western steam engine who works on Duck's branch line. He escaped the dreaded scrapyards of the Mainland, mainly thanks to Douglas, but also as the result of sympathetic signalmen, luck, and using "goods only" routes under cover of darkness, with some close calls along the way. He also has a brakevan name Toad.
