Mount Uetliberg 0-6-0 Locomotives in Switzerland


Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 15544)

Data from "Working Heavy Grades in Switzerland", Locomotive Engineers' Monthly Journal, Vol 9, No 8 (August 1875), p. 405.

When Swiss promoters of the spectacular view 1,300 feet (396 metres) above Lake Zurich began planning a tourist railway to scale the mountain's flanks, they settled on adhesion-only traction for the 5 1/2 miles (9.1 km). 59% of the entire line climbed at more than 264 feet/mile (50 metres/km) or 5%. Curve radii of 450-500 feet (137.1-152.4 m) ruled with one 450-ft curve combining with a rise of 327 feet (62 m/km) or 6.2%.

Each train would be pulled by one of these tanks and consisted of four cars carrying 40 passengers each for a trailing load of 17,500 kg (38,581 lb). Climbing speeds averaged 8.1-10.6 (13-17 km/h). A compressed-air system already in use on the Rigi Railroad permitted descents at 15.5-18.6 km/h (25-30 km/h)
