Data from "Colliery Tank Locomotives," The Engineer, Volume 61, No 3 (15 January 1886), p. 45.
Built around the same time as the much larger 0-6-0ST standard-gauge saddle tank shown in Locobase 20243, this little locomotive worked for eight hours on a very specific duty. As Engineer reported, it was designed "for taking coal from the crushers and running over the top of coke ovens for the purpose of charging them." It was "necessarily light, partly to avoid doing damage to the ovens and partly to suit a light section of rails which were on the ground."
Its ability to charge 120 ovens a day had done away with "a great deal of manual labor which was formerly employed for this purpose." Questions such as "Did manual coke oven charging present significant risk to human laborers?" and "Were the displaced workers assigned other tasks at approximately equal pay?" suggest the ambiguous effect of applying new technology during the Industrial Revolution.
Engineer also underscores a core quality of steam locomotives. The big saddle tank and the little side tank were "interesting examples of the applicability of the locomotive to very diverse purposes."
