Last October, the Rhaetian Railway parked the 6 ABe 4/4 # 51 to # 56 railcars on the Bernina line. As a result, during the summer half-year, when the various Bernina Express trains are running, there is now an average shortage of around 2 “Allegra” dual-current railcars (ZTZ) to cover all services, especially on the Bernina and to Arosa. For this reason, push-pull trains with Ge 4/4 IIs are now used between Chur and Arosa, and freight trains are also operated with two Ge 4/4 IIs. Regional train 1433 of the line R16 from Chur to Arosa is crossing the 62 meter high and 284 meter long Langwieser viaduct, built in 1912 to 1914. When built is was the largest concrete bridge of the world.
