The unique steam railcar CZm 1/2 # 31, built in 1902 by Emil Kessler, Esslingen/Germany, running for SBB Historic, but operated and maintained by Dampfgruppe Zürich (Steam group Zürich), suffered severe damage in Sihlbrugg on 20th february 2016, when it had a brunt to wrong parked ballast cars. Now it is repaired in the RhB works at Landquart and made a successful test run today to Domat-Ems and back. On the return journey, the vehicle was turned on the turntable in Chur, so the footplate is in front again.
