Steam railcar CZm 1/2 # 31 of the former Uerikon-Bauma-Bahn (UeBB) is running for the last time on his original line between Bubikon and Wolfhausen, a branch which was never electrified and will be cut from the SBB network shortly. The unique vehicle, built in 1902 by Esslingen/Germany, is pulling the "Shell" tank car and the X 309, a former L6, of DVZO.
