In wintertime, when the road over the Oberalppass is closed, the MGB (Matterhorn-Gotthard-Bahn) is running car transport trains between Andermatt and Sedrun and vice versa. On this day, for engineer training on this particular locomotive, the HGe 4/4 I # 36, which is now owned and operated by association MGBahn Historic, was pulling these trains. Here is train Az 2833 from Sedrun to Andermatt, fully loaded with cars, the drivers and occupants travelling in the passenger car, is on the cogwheel section between Oberalppass and Nätschen. The 911 kW locomotive was built in 1948 by SLM and MFO for the Furka-Oberalp-Bahn (FO).
