A metre gauge train of the
<a href="http://www.selfkantbahn.de/">Selfkantbahn</a> makes round-trips on the
Open Day at the Wildenrath Test Centre of Siemens on 25 August 2002. It is
running on the small test ring (2485 m long) which is equipped with two gauges.
Note the third (actually the fourth) rail and the catenary with double contact
wire for DC operation.
