steam loco G 8.1 K.P.E.V.

Prototype: The steam locomotive Preußische G 8.1 was a further development of the G 8 by Robert Garbe and was initially referred to as the "reinforced normal design". It had a larger boiler and the resulting higher weight was intentional in order to also increase the tractive effort through the higher frictional weight. Because of the high axle pressure, however, the G 8.1 could only be used on main lines. In addition to heavy goods traffic, heavy shunting service was later added as a field of application.
The G 8.1 was the most frequently built state railway locomotive and the second most frequently built locomotive type in Germany after the DR series 52 built 20 years later. For the Prussian State Railways and finally for the German Reichsbahn, 4,958 units alone were built.
