Bulgy is a double-decker bus, who was once very opposed to railways.
Bulgy was first seen bringing passengers to Arlesburgh, and was rude to Duck claiming that roads were better than rails and that railways would be ripped up one day. Later, his friend came to take his passengers, leaving him free to steal Duck, Donald, and Oliver's passengers claiming he knew a "shortcut" to Tidmouth. He got his comeupperance when he wedged himself under a bridge. Duck took the passengers, but Bulgy was placed in a field nearby and became a henhouse. Years later, he was put back into service when the engines had more than enough passengers and Thomas and Emily in need of repairs. He enjoyed it until some hens that crept aboard the night before startled the passengers and his Driver. Soon afterwards, after Emily's suggestion, he became a vegetable bus. He likes it because they don't lay eggs and they never complain.
Bulgy was a very rude and bad-tempered double-decker bus. After being restored, he saw the error of his ways and changed his attitude about railways, but he's still grumpy. Although, he often has good intentions.
Bulgy was previously painted red and cream, but after becoming a vegetable bus he was painted green and cream. He has since gone back to his old livery. He has a sign on his left side reading "Railway Bus" and an opposing sign on his left side reading "JOIN THE ANTI-RAIL LEAGUE". He also has a sign on his front and back, reading "FREE THE ROADS".
