Data from Vulcan Foundry website -- [], accessed 14 July 2007. Boiler pressure is an estimate. Works #311-315 in 1848.
The drawing doesn't have much more than the data shown on the drawing. Unlike most 0-4-2s, these were described as "goods engines". They had long, slender boilers with widely set drivers and nearly square bore/stroke ratio.
