and as a result good curve-running performance. In addition the carrying axle had a side play of 10 mm. It was returned to its centre position by sloping bearing surfaces (geneigte Doppelflächen). The grate area of the firebox turned out to be very small; as a result its steam generation was not particularly satisfactory. Trials with ribbed tubes did not produce any improvements.

The outside wet-steam engine had inside valves and drove the first coupled axle. The wheels were sprung with leaf springs located over the top, that were linked by a compensating lever between the coupled wheels.
The vehicles were equipped with tenders of classes 2 T 8 or 2 T 6.67. Several locomotives were equipped with rearward-facing driver's cabs on tenders. This enabled them to work routes without a turntable.
Steam locomotive
A steam locomotive is a railway locomotive that produces its power through a steam engine. These locomotives are fueled by burning some combustible material, usually coal, wood or oil, to produce steam in a boiler, which drives the steam engine...
