Toad worked with Oliver on the Great Western Railway before being threatened with the prospect of scrapping. Oliver, Toad, and an autocoach named Isabel ran away for the greener pastures of the North Western Railway, but Oliver ran out of coal en route. Luckily, they were rescued by Douglas and brought back to Sodor. In the Railway Series, Toad asked to be Douglas' brakevan as a show of thanks. In the television series, Toad remains as Oliver's brakevan.
