Locobase 21265 describes the Krupp eight-coupled tank delivered in 1932 to support construction of a large coal-mining complex for a company exploiting coal reserves in Lorraine.
Three years later, Krupp delivered this powerful five-axle version built to the same 16 metric ton axle loading requirement. The extra axle placed ahead of the other four meant a larger boiler set to a slightly lower pressure. Curve radii limitatioins may have dictated the over-square cylinder dimensions, which made available 59% more cylinder volume.
