Temporary 1-meter gauge railway track approximately 100 meters long in Rigi Scheidegg, celebrating 150 years since the opening of the Rigi-Scheidegg Railway in 1875, with steam locomotive G 2/2 "Ticino" of Martin Horath. The Rigi Kaltbad-Scheidegg Railway (RSB), also known as the Rigi-Scheidegg Railway or Kaltbad-Scheidegg Railway for short, is a former Swiss narrow-gauge railroad. In Rigi Kaltbad at 1423 m above sea level, it connected to the Vitznau-Rigi Railway built in 1871 and ran to Rigi Scheidegg at 1648 m above sea level. When it was completed, it was the highest adhesion railroad in Europe. The 6.7-kilometre metre-gauge line was opened in July 1874 from Rigi Kaltbad to Rigi First and around a year later to Rigi Scheidegg. The railroad was never economically viable, the line was closed in 1931 and the track was finally demolished in 1942. To mark the 150th anniversary of the opening of the Rigi-Scheidegg Railway, a 100-metre-long track was laid at Rigi Scheidegg and steam operations were carried out on two weekends with Martin Horath's two-axle Ticino steam locomotive. The locomotive was built in 1889 by Arnold Jung in Jungenthal/Germany.
