Notes

The road to Arosa is twisty, steep and narrow, so the narrow gauge railway is used for most larger things instead. Most of the time, it is just attached to regular passenger trains: Freight going up (from Chur to Arosa) is put at the end of the cab car, freight going down at the end of the locomotive (the locomotive is always facing up). That way, for example, the collective trash of Arosa came down. And yes, it did smell like it looks here.
