In the moment, two of the six ALVRA trainsets of the Rahetian Railway for the Albula line are not in service. 1 train has to undergo warranty works and 1 train was damaged in a derailment (rock on the track) near Sils im Domleschg on october, 26th. So the RhB is forced to run two replacement compositions, both with "Allegra" railcars and Bt cab cars. This is the Interregio 1136 from St.Moritz to Chur, crossing the 65 meter high Landwasser viaduct between Filisur and Alvaneu. The cars in the train are of type standard II, the "Allegra" ABe 8/12 # 3506 is in the rear shoving the train towards Chur.
