Tosstalbahn 0-4-0 Locomotives in Switzerland


Class Details by Steve Llanso of Sweat House Media

Class Wald (Locobase 5118)

[link] (August 2002) notes that this engine served the TB for 6 years, after which it moved to the Gotthardbahn. Although limited by its tiny wheels to 30 km/h (19 mph), the locomotive proved useful enough to stay with the GB until 1913.
