The very interesting dynamometer measuring car Xd4 # 99701, built in 1913 for the SBB, now rebuilt as private owned parlor car, in the train 31035 from Winterthur to Geneva, during a stop in Baden. The car was renovated by Historic Rail Services Gmbh in Winterthur, the bogies by the RhB in the Landquart work shop. From 1979 used as parlor car As 411 by the Oensingen-Balsthal-Bahn, then withdrawn and stabeled in Kallnach. In 2017 bought by a group of enthusiasts, now a small association. The interior of the car, which is created in front work, is not yet completely finished
