"Bertie the bus came to the Island of Sodor soon after Thomas was given
his branch line. Like Thomas, he lives at Ffarquhar. Once he rescued
Thomas's passengers when he got stuck in a snowdrift. He also had a race
with Thomas, though Thomas won. Now they keep each other well supplied
with passengers and are the best of friends."
"Bertie has a great deal in common with Thomas. Ever since their great
race they have been the firmest of friends. Bertie's strongest
characteristic is his friendly grin and his readiness to help
any engine prepared to admit that - just sometimes - roads
have their uses as well as rails."
