The Bergbahn Rheineck-Walzenhausen operates a single 1200 mm gauge
electric rail car on a 2 km long railway partially fitted as a rack
On the date of my visit, Tuesday April 26th, 2004, the one electric railcar was being overhauled and the rail service was replaced by a mini-bus. The mini-bus operating the replacement service appears to have been borrowed from the nearby Rorschach-Heiden-Bergbahn. This is train RB81 (17:14 from Rheineck).
