Thomas and Bertie - UK/Thomas and Bertie's Great Race - US is the fourteenth episode ever made in Season 1.
Thomas meets Bertie, the bus who took his passengers home after he crashed into a snowdrift. Bertie claims to be faster than Thomas. Thomas denies his claim and to settle the matter, they decide to have a race. Bertie manages to stay in front for the majority of the race, but Thomas passes him at the tunnel and barely wins.
