Glenfinnan station, still served by ScotRail trains on the West Highland Line, keeps its old booking office and signal box as a small museum of the line's history. A couple of old carriages on the siding serve as a dining car.
It's a pleasant, low-key complement to the viaduct, and the trail from the station to the viaduct viewpoint is one of the better ways to see the Jacobite steam train pass.
