Rusty to the Rescue

"Rusty to the Rescue" is a fourth season episode.

Plot
Rusty enjoys visiting a forest railway called the "Bluebell Railway", but Rusty's driver is concerned that the line needs an engine, and so Rusty consults Douglas. During the conversation, Douglas mentions that only diesels travel to the Other Railway, which is where he found Oliver. That suits Rusty, and the next day he travels to the Other Railway, slipping past the diesels by lying he is an inspection diesel. He finds a tank engine hiding on a siding, and convinces him to travel with him to Sodor. They make it there, and the engine, Stepney, finds a new home on the Bluebell Railway.
