Bio in the television series

Bertie is continuously alluding to his race with Thomas and how he could win 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.


Bertie is friendly and ready to help anyone in need, but can't resist teasing Thomas about being slow.


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


Bertie is painted in the common red livery of buses in the United Kingdom, mostly famously used by London Transport. His number plate, "CRD54", refers to the fact that it was first seen in Edward the Blue Engine, published in 1954, and illustrated by C. Reginald Dalby.
