The Engadine line, was opened on 1 July 1913, and was the first Rhaetian Railway line to be electrified from the start at 11 kV 16⅔ Hz AC. Since the opening of the Engadin line, this railway has attracted thousands of tourists every year, and to this day is in the top 15 most scenic railway lines in Europe, going through the beautiful inn valley the locos: The Rhaetian Railway Ge 6/6 ᴵᴵ is a class of heavy metre gauge electric locomotives operated by the Rhaetian Railway, which is the main railway network in the Canton of Graubünden, Switzerland Here are some pictures from the train simulator version:
Excellent idea and if you own this one it should be able to layer the Ge 6/6 locomotive to Arosa Line and In return Arosa Line gives the Ge 4/4 to this route.
The Ge 6/6 II is not operated on the Arosa Line. The main purpose of the 6/6 was to haul heavy freight trains over the Albula Pass. They were also used in front of express services on that line. But freight-only services on the Arosa Line are very rare, freight waggons are commonly added to the back normal passenger services. If they run a freight-only service this will be hauled by the Ge 4/4 II. But indeed the Ge 4/4 II can be layered onto this route.
