description
In the six vehicles from Keßler, experiments were carried out with a boiler of the Keßler design. This had a pear-shaped cross-section and could therefore be placed deeper between the wheels. The Hartmann machines tried to achieve the same effect by using two kettles, a lower kettle with a small diameter and a larger upper kettle. After two boiler explosions, all vehicles were equipped with normal boilers. All vehicles had the steam dome in the middle, the overhanging standing boiler had a smooth fire box on which there was a safety valve and the drive pump driven by the crossheads. They were with a Tender equipped Bavarian design 3 T 5th
