Steam rail car CZm 1/2 31 of the former Uerikon-Bauma-Bahn, now SBB Historic and operated by Dampfgruppe Zürich (steam group Zurich), with a charter special train for a 50th birthday party, pulling car C 106 of the DVZO. The steam railcar comes fresh from a overhaul by Dampfgruppe Zürich (Changing all pipes in the boiler, repair of the boiler, new roof, new painting, partly new ceiling etc.)
CZm 1/2 31 was built in 1902 by Maschinenfabrik Esslingen for the SBB, but sold to the UeBB in 1907. Since 1980 it is operational again for SBB/SBB Historic.
