For the heavy express train service in the hill country, the Prussian KPEV had a four-coupled three-cylinder locomotive developed instead of replicating the proven Saxon XX HV with four cylinders. Borsig's design was then implemented, although the required maximum axle load of 17 t was exceeded by almost 2 t, meaning the locomotive could only be used on a few routes. With its output of 1,620 hp, it reached a top speed of 110 km/h. When most of the main routes were upgraded for an axle load of more…
In order to determine the suitability of the different drives for heavy freight service, the German Deutsche Reichsbahn-Gesellschaft DRG included five-coupled tender locomotives with two and three cylinders in its standard locomotive program. In 1927, ten of each type were initially built. A further 35 of the 43 with two cylinders followed in 1928. In comparison, the two-cylinder locomotive proved to be equal to the three-cylinder locomotive known as the 44 series up to the medium power range more…
In the mid-1950s, the boilers of the BR50 standard locomotives of the Deutsche Reichsbahn DR had reached the end of their service life due to the use in heavy freight traffic. Since the DR was unable to obtain replacements for its 50s, which were universally applicable with an axle load of just 15 t, in the foreseeable future, it was decided to reconstruct many locomotives with a boiler largely equivalent to that of the new BR 23 locomotive. From 1957, the DR reconstructed a total of 208 more…

In 1943, the operational sites in the Wehrmacht-occupied areas in the east demanded more powerful steam locomotives for the supply freight trains. Borsig submitted the design of a (1’C)D h4 with an axle load of 20 t. Although the powerful locomotive was not released beyond the project stage, model railway manufacturers took the 53 in H0 and I gauge as a model. The sound comes from an original Mallet locomotive that is similar in terms of drive technology to BR 53.
The class 62 express tank locomotive was part of the standard locomotive program of the German Reichsbahn-Gesellschaft (DRG). The 1,680 hp two-cylinder locomotive was designed for service on short main routes where the idea was to avoid turning the locomotives in the terminal stations in favor of short turnaround times. The drive wheel diameter of 1750 mm was a good compromise for good acceleration and a top speed of 100 km/h. During the DRG era, the 15 locomotives proved their worth, for more…
The new locomotive program of the Deutsche Reichsbahn DR after WW II contained a tank locomotive with a drive wheel diameter of 1,600 mm and a top speed of 90 km/h. The 88 1'D2 'tank locomotives designed for commuter train service had an axle load of 18 t. The well-dimensioned boiler and the carefully developed engine provided practical pulling power and good acceleration. Since the DR converted various branch lines to an axle load of 20 t, various 65.10 were equipped with a compressed air bell more…
In the early 1930s, the Deutsche Reichsbahn-Gesellschaft DRG included a light 1’B1’ tender locomotive for branch lines in its standard locomotive program as a replacement for light regional railway tender locomotives that could be used to pull passenger and freight trains. It was intended to be used where modern diesel railcars were too inflexible due to fluctuating passenger numbers or too weak due to the additional freight wagons that had to be carried. In order to reduce personnel costs, the more…
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 more…
