The engine was based on that of the Class P 4.1 that had
Hanomag had produced in large numbers since 1892. It had slightly larger wheels and, due to its new design, significantly fewer heating tubes. The superheater and the steam engine were entirely independent designs.
Service and preservation
In 1898 a one-off was delivered by
Hanomag to the
Prussian state railways. The economy of the superheated system was soon proven in 1899 by the engine during trial runs from
Kassel. Apart from a short stay at Halle the engine was assigned to Kassel as Cassel 131 and, from 1906, as P 4 Cassel 1846. In 1921, after the
First World War, the engine was mothballed, along with many other machines of similar class. With its sectioned boiler the P 4 stood for a long time in the Transport and Construction Museums, part of Museum of the Present at
Hamburger Bahnhof in Berlin[clarification needed].
