Bertie the Bus

Bertie is a friendly bus, who is always ready to help anyone in need, but can't resist teasing Thomas about being slow. Bertie is continuously alluding to his race with Thomas and how he could win the next time. He actually raced Thomas again in the seventh season episode Three Cheers for Thomas, but only won because Thomas was sidetracked with collecting the sport medals.

Basis
Bertie is based on an AEC Regal "T Class" London Country Area bus.
