Class K44.7 / 99 261 (Locobase 6534)
Data from Christian Lindecke's [

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.
