After about 2 years standstill due to the Covid-19 crisis, the unique steam railcar CZm 1/2 # 31 of SBB Historic, maintained and operated by steam group Zürich (VDZ Verein Dampfgruppe Zürich), made a transfer run with passengers from Zürich via Oerlikon-Regensdorf-Wettingen-Mellingen-Othmarsingen to Brugg AG, for a charter run the other day. Now the railcar is entering Mellingen to take water. This vehicle with 30 seats, a mail compartment and 45 km/h maximum velocity, was built in 1902 by Maschinenfabrik Esslingen/Germany for the Nordostbahn. In 1906 already, the CZm was sold to the Uerikon-Bauma-Bahn and got a new boiler. Withdrawn in 1948 and stabled by the SBB, operational again since 1980 as historic vehicle, since 2005 operated by VDZ.
