Bulgy is a double-decker bus, who was once very opposed to railways in the Railway Series and Thomas the Tank Engine and Friends. In Season 3, he is evil and mean, but in Season 7, he became much calmer.
Bulgy hated railways, and believed that some day they would all be replaced by roads. He even carried a poster on his side telling people to "JOIN THE ANTI-RAIL LEAGUE". His favourite phrase is "Free the roads!"
Bulgy tried to steal Duck and Oliver's passengers by pretending to be a railway bus. Bulgy was determined to get the passengers to Tidmouth before Duck, but got stuck under a bridge after attempting to take a short cut. His lies were exposed, and soon "nobody would believe his destination boards". Eventually he was turned into a henhouse and placed near the bridge, now nicknamed "Bulgy's Bridge".
Bulgy was later brought back to the road to help with passengers while Thomas and Emily needed repairs, but the chickens who had lived in him nestled in his luggage racks and caused trouble the following morning. He was then turned into a mobile vegetable stand. Bulgy enjoys his work delivering vegetables, because they do not lay eggs and they never complain.
The Official Website states that he is now a refreshment stand. However, this could be a mistake.
In magazines, he has been converted into a playbus and a greenhouse.
