Jura-Bern-Luzern-Bahn 0-6-0 Locomotives in Switzerland
Class Details by Steve Llanso of Sweat House Media
Class G 3/3 (Locobase 8047)
Data from [
]
These were small six-coupled tanks that operated on the relatively flat Interlaken-Meiringen and Giswil-Lucerne sections. That the ten loks had SLM works numbers 475-476 (1887), 496-498 (1888), 584 (1889), 880 (1894), 1089 (1898), and 1342-1343 (1901) shows over how long a period the class was acquired. The Chemin de fer BiFre-Apples-Morges (BAM) bought three more from the same batch that delivered the 306 to the JBL. In 1903, the SLM delivered two more to the Montreux-Oberland Bernois-Bahn (MOB). These had smaller drivers
By 1905, they were being superseded by G 3/4s. The first three were retired in 1911. K.u.K Hersverwaltung
