Whilst travelling along his branchline, Thomas and the Fat Controller discovered one of the stations had been vandalized. Later on the journey, Annie and Clarabel discovered an old coach in an overgrown siding. After their journey, Annie and Clarabel suggested to the Fat Controller that he should have the old coach renovated and converted into a new station building. The old coach was very grateful to be put back into good use again as a station building - hence her name, the station coach.
