mineral traffic on narrow gauge 0-4-0 Locomotives in France


Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 11167)

Data from "Locomotive Engines at the Paris Exhibition", The Artizan, Vol II, 4th Series, #2 (11 February 1868), p. 28 and "Sir David Campbell on Railway Apparatus", Reports on the Paris Universal Exhibition 1867, Volume IV (London: George E. Eyre and William Spottiswoode, 1868), pp. 497.

Campbell described this little tank as "beautifully finished" and noted that it could negotiate curves as tight as 16 yards radius and scale grades of 1 in 16 (6 1/4%). Altogether, he added, "it is a very handy little engine." Indeed, its proportions suggest a free-steaming locomotive with good traction.
