Intro. Sodor has barely any engines to begin with as here, in this timeline, the island was just barely getting by. Henry was in his old hybrid of a C2 Atlantic crossed with a LNER A1, giving him bad smokebox conditions so he was constantly sick, Gordon is green and just came onto the island as a new express engine but is too arrogant and isn't as wise as he will be in the future, Edward is in his old red Furness Railway Maroon colour, and Thomas is black wearing his good old black E2 Tank Engine colours. There are many loaned engines, so I won't name any so you can.

Sodor 1920s
