Prussian T 10

For the operation of passenger trains on the route between Frankfurt am Main and Wiesbaden, the T 10 was developed as a powerful and fast tank locomotive in order to be able to do without turning at the terminal stations. In order to save development costs, assemblies from locomotives already in use were used as far as possible. The cylinders and chassis were taken over from the P 8 because it had good running characteristics. The result was a two-cylinder engine using superheated steam, which had a 4-6-0T wheel arrangement and could reach a speed of 100 km/h with a coupling wheel diameter of 1,750 mm.

In order to be able to accommodate the weight of the supplies, however, a lighter boiler had to be used and that of the P 6 was used. Finally, this was moved forward to make room for the coal bunker in the rear of the locomotive. In operation, it turned out that the running properties when reversing were worse than hoped due to the missing trailing axle. This was exacerbated by the fact that the load on the last coupled axle changed depending on the level of supplies. So the locomotives were rotated more frequently than originally planned in order to be able to run in both directions at the same speed.

A total of only twelve engines were built between 1909 and 1912, which were used almost exclusively on the intended route. After the war, only one of them had to be handed over to France, the remaining eleven were all taken over by the Reichsbahn a few years later. They were given the numbers 76 001 to 76 011 and their number was reduced to eight by the end of the Second World War. The Bundesbahn immediately gave them away, but all but two were taken over by the Osthannoversche Eisenbahnen (OHE). They were used in north-eastern Lower Saxony until they were phased out in 1964 as passenger train services were increasingly discontinued.
