Steam locomotive G 3/3 No 6 Waldenburg Railway WB 1912 The railway between Liestal and Waldenburg was constructed in the middle of the 1880 economic crisis. Curves with very small radii were used to save construction costs, so it was built to a gauge of 750 mm, the narrowest used on any public railway in Switzerland. In 1912, the SLM delivered locomotive No.6. Railway enthusiasts preserved it from being scrapped, and in 1958 it became the first railway vehicle to enter the Transport Museum.
