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 1437 of the line R16 from Chur to Arosa with Ge 4/4 II # 633 in the RTR publicity paint scheme is running uphill between Peist and Langwies. Second car, a standard car type I second class has the "Bärenland" publicity paint scheme.
