Toad is Oliver's Brakevan. They were both saved from scrap by Douglas and are very grateful to him. Toad has no time for the insults of Troublesome Trucks and works happily alongside Oliver on Duck's branch line. Toad is always coupled to Oliver so he is facing backwards. This is fine with since some Troublesome Trucks played a trick on him and he learned that traveling backwards can be very useful.
Toad is part of the magical world of Thomas & Friends. The engines all work and play together on the Island of Sodor. While they are doing their very useful work, they learn important lessons about friendship and getting along. Many of the characters are available to purchase as part of different toy brands, including the timeless Thomas & Friends Wooden Railway Series. You can purchase Thomas and many of his engine friends, as well as wooden track, buildings, destinations and sets from the simple oval to the Deluxe Tidmouth Sheds set. Many engines are available on a limited basis and are retired, so check ebay or other online auction sites for your favorites if you can't find them here or in a store near you.
