The cogwheel steamlocomotives H 2/3 # 17, built in 1925 by the SLM Winterthur for the Vitznau-Rigi-Bahn (VRB), was steamed up for the first time this year, and so brake tests were on the agenda. The Xm # 1 snow blower, weighing around 20 tons and built by Robert Aebi in Regensdorf, served as the load.
