To speed up express trains on the relatively short 41 km route between Frankfurt and Wiesbaden, the Prussian state railway KPEV had a new, powerful tank locomotive developed. The engineer responsible, Robert Garbe, decided to marry the slightly shortened chassis of the P8 (later BR 38.10-40) with the boiler of the P6 (BR 37.0-1) and thus created the T10. The twelve samples of the 880 hp, 100 km/h two-cylinder locomotive proved to be up to the task and were in service with the KPEV and DRG for 30 years. In the mid-1940s, the now numbered BR 76 was discontinued and from 1946 one locomotive was sold to the Ilmebahn and six more to the East Hanoverian Railways OHE, with the last one not being retired until 1964.
