Notice, too, that this loco has a bar across the front of the engine to prevent it from dropping onto the ties if it derails. The bar lands on the rail before the wheels hit the ties, a feature that was quite common on United Kingdom narrow gauge locos. If the drivers aren't down on the ties, it's a lot easier to get them back on the rails!
As for the five man crew, this is also the railway on which two crewmen are stationed on the footboards on the front of the locomotive to pour sand on the rails as the train climbs the steep grades on the line.
