More About Thomas the Tank Engine

Bertie teased Thomas about being slow, but had to eat his words after breaking down.

Thomas and Victoria

Bertie was mentioned as being sick and unable to help Toby and Henrietta with carrying the quarry workers.

Thomas and his Friends

Bertie was mentioned to have helped pick up visitors who wanted to see the bust of the Thin Clergyman unveiled after the partial collapse of Henry's Tunnel.

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 and Thomas have seemed to continue this tradition of racing. However, in the seventeenth season, he was re-routed giving him an advantage. Thomas is still able to beat him occasionally.

In the nineteenth season, he teased Thomas by telling him about what was on the other side of a mountain on his branch line. Thomas was cross by Bertie's teasing and became determined to find out what was there.

In Sodor's Legend of the Lost Treasure, while he and Thomas are racing, Thomas nearly collides with Toby, and he nearly collides with Oliver the Excavator. He was then seen on the road by the Harwick Branch Line. Sheep were in his way, but Bertie just smiled.


Bertie is friendly and ready to help anyone in need. However, he can be quite cocky and boastful about himself, especially to Thomas, always joking around and teasing him about their races. He can sometimes be quite grumpy, as whenever he breaks down or gets stuck, he grumbles about it. He is always, however, easy-going and cheerful to everyone he sees.


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.

Bertie on the Big Screen

Bertie was voiced by Kevin Frank in Thomas and the Magic Railroad. In the film, when Thomas heads off to find Mr. Conductor after the meeting with the engines, Bertie told Thomas to have a race, but Thomas is no time and apologising to Bertie when he unable to race with him. Later, Bertie passes and greets Thomas that he has five coal trucks instead of six.
