The RhB Tm 2/2 115 is shunting at Ilanz station

When there are no trains the tiny locomotive (classified as a rail tractor in Switzerland) is moving the cars that arrived with the previous train for unloading and gathers the cars for the next shipment. There is a loading siding at the station (you can see it in this picture with two flat cars loaded with dust silo canisters), a container terminal by the next Rhein bridge and it's also the job of the little orange machine to collect the cars from the stations between Reichenau-Tamins and Trun (both excluded).
