LAG 0-8-0 Locomotives in Germany


Class Details by Steve Llanso of Sweat House Media

Class K44.7 / 99 261 (Locobase 6534)

Data from Christian Lindecke's [] (visited 27 May 2005), supplemented by [], last accessed on 12 May 2011.

This big 8-coupled tank (Maffei works #4200) had an outsized amount of superheating surface for the boiler's size, even when accounting for the evaporative heating surface measurement on the fire side. By the specs at least, it looks like a herculean metre-gauge hauler.
