Thomas the Tank Engine & Friends

Thomas and the New Engine (9x11)

:

Thomas sees a new engine, who seems to be getting along very well with diesels, Iron ‘Arry & Bert, so well in fact that they’re laughing and everything. But the engine is steam powered. A steamie who’s friends with diesels? Certainly this cannot be? But does Thomas have his facts straight? Surely he couldn’t be mistaken?
