As of 2009, this locomotive is still used in historic rides. Built in 1858 (the plate on the loco and other sources show the later date, 1873). It is the oldest Swiss loco surviving and also the only remaining standard gauge rack fitted vertical boilered loco in the world. The two cylinder steam engine provides 196 PS power under 7.5 km/h speed. The loco was removed from service in 1937, when the railway was electrified, but was returned in 2009.     Rigi Bahnen number 7 climbs the mountain above Lake Lucerne for the first time after 12 years in the Swiss Transport Museum Lucerne. Red car B5 dates from 1871 and was rebuilt new in 2009 - 21 May 2009 Gorg Trüb.
