VE / PLM 0-4-0 Locomotives in France


Class Details by Steve Llanso of Sweat House Media

Class 2 390 (Locobase 13366)

Data from the PLM Wiki vault crammed with data and plans at [link].

Yard switchers that operated for decades, later renumbered several times. Data given represents locomotives in 1869. These were renumbered in 1872 as 3 803-3 807. For some reason, 3 807 was withdrawn in 1878 and another in 1881. The last three, since renumbered 7 001-7 003. Two -- 7 002-7 003 -- were retired in 1912 while 7 001 ran until 1918.


Class 2 395 (Locobase 13367)

Data from the PLM Wiki vault crammed with data and plans at [link]. Data as of 1869.

Yard switchers built to the same general specs as the Cockerill locomotives described in Locobase 13366. The builder produced both locomotives and steamships and sold its locomotive facilities to Sharp, Stewart in 1863.

After their renumbering as 2 808-2 313 in 1872, boiler pressure was raised to 9 kg/sq cm (8.8 bar) and evaporative heating surface area grew to 72.63 sq m.
