Data from "Tramway Locomotive", Engineering, Vol (21 December 1900), pp. 797-798. Works numbers were 918 in 1895; 973-975 in 1896, 1019-1022 in 1897, 1203-1205 in 1898.
Described in the account of this design's appearance at the 1900 Paris Exhibition as "of a type well known and approved in Switzerland and on the Continent generally", these dozen tram motors served in eastern France. They were credited with rounding curves as tight as 50 metres and being able to reach 30 kph (18.6 mph).
Although hidden from view by pedestrian-friendly panels enclosing the running gear, the cylinders lay outside of the boiler and well back along the frame. They drove the three tightly-spaced axles through rocking shafts.
