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 2824 from Andermatt to Sedrun, loaded with one car only, the driver travelling in the passenger car in the rear, is on the cogwheel section between Nätschen and Oberalppass. The 911 kW locomotive was built in 1948 by SLM and MFO for the Furka-Oberalp-Bahn (FO).
