Tilting test train with diesel railcar VT 612 # 901/902 of Deutsche Bahn Systemtechnik Minden, pulled by ICN RABDe 500 # 031 of the SBB, on a transfer run over the Gotthard mountain line from Bodio to Erstfeld, in the Wattinger curve at Wassen. Since there are no tilting trains running over the Gotthard mountain line any more, the train is only on a tranfer run. In the past, such test runs took place periodically to check the conditions (track position, etc.) for the increased speeds of the N series of trains (tilting train).
