From the other angle. It was a single short platform, squeezed in to this little inset in the cliff face. Here you'd have been looking at the station wall, with the entrance and office at the far end. In this photo on Pinterest you can see the three tracks—the main platform track, a run-around loop so the engine could make its way around the carriages and onto the other end of the train, and a siding. At the far end is the station master's house, just behind a turntable that would have been used to turn the engine fully around for the return journey.
