Choindez 0-4-0 Locomotives in Switzerland


Class Details by Steve Llanso of Sweat House Media

Class E 2/2 - 1911 (Locobase 6394)

Data from [] Works number 3055 for this Brownian double-lever drive tank. Like the similar locomotives shown in Locobase 6393, this was an industrial switcher that served for more than 90 years. Its proportions grew significantly, however, and #9 seems to have been one of the biggest 4-coupled tanks in Swiss service. In 1998 the Swiss preservation group La traction bought #9.
