Cogwheel train of the Rigi Bahnen with railcar Bhe 2/4 # 4 of 1953 and car B # 16 of 1925 is running the train CC 1122 from Rigi Kulm to Vitznau, crossing the Schnurtobel bridge between Grubisbalm and Mittlerschwanden. This railcar got a publicity paint scheme for the Migros Luzern (large retailer) in 2019. The concrete Schnurtobel bridge, in the maximum grade of 25.0 %, was built in 1957/58, replacing an old truss bridge from 1871, when the line was built.
