German light military railway locomotive type KriegsDampfLok 11 built by Schwartzkopff beginning in 1939 and Franco-Belge in 1944. Note the "oversquare" cylinder dimensions in which the stroke was shorter than the cylinder diameter.
In Austrian service, it was designated 699.1. This small locomotive was a tank & tender design (also known as a "half-tender") in which the engine could operate on its own fuel and water for a short time, but usually trailed a small tender. One set of data shows the on-frame tank holding just 0.6 cubic metres of water and the locomotive bunker just 0.5 metric tons of coal.
It was designed to operate on several gauges including 600/760/785/800 mm
Club 760's description (translated by Google) adds flavor to this entry with vignettes of German feldbahn operaton as World War II as the walls closed in:
" Two seats for armed train attendants are provided on the tender to protect the locomotive crew. Evil tongues claim that the locomotive crew could not run away. In total, towards the end of the war, eight machines of this type were transferred to the Alpine Fortress, where they were informally handed over by the transport officer in Bregenz, who immediately left with an unknown destination!"
