The green bus was a passenger bus, who was later turned into a hospital bus.
This bus was one of the buses who took over Toby's old tramway, Causing Toby to have no more work left for him. Toby later told the story of his old tramway to Thomas and Percy. During those days, Toby and Henrietta were unhappy with the buses taking all their passengers, but got their passengers back when one of the buses (the green bus) crashed onto some roadwork. The green bus later came to work on Sodor, and was turned into a hospital bus. Some teddy bears were once put into the green bus.
The Green Bus is painted green with a big white stripe on either side.
The green bus is a AEC Regal "T Class" London country area bus. Bertie is also a member of this class.
- The green bus was only depicted with a face in the annual story, You Never Know.
