This idyllic metre gauge mountain railway in the Swiss Canton of Graubünden, offers beautiful panoramic views, unique roadway running similar to that of a tramway, incredible civil engineering structures including 41 bridges (notably the 284m long Langwieser Viaduct) , 19 tunnels, 12 avalanche-protection galleries, and a sheer grade of 6% that most railway engineers wouldn’t consider viable.

Taking control of RhB’s iconic Ge 4/4 II electric loco, your journey starts in the Canton of Graubünden’s capital of Chur, and snakes through 25.6 Kilometres of the Swiss mountains and up the Schanfigg valley, climbing 1155 vertical metres without any assistance from rack and pinion support or banking locomotives. Your journey terminates at 1739 metres above sea level in the wonderful spa town of Arosa, a popular ski destination in the snowy season.

Over the coming weeks, we will be showing off plenty of Arosa Linie: Chur - Arosa screenshots and videos. You can look forward to interviews, detailed developer videos and more. Make sure you don't miss anything on Arosa Linie by following @trainsimworld on Twitter and Facebook.

In the meantime here are few shots to give you a taste of what you have to look forward to.
