For increase of traction power and to gain coal efficiency few locomotive manufacturers had developed steam turbine locomotives in the 1920s till 1940s. In 1926 German Lokomotivfabrik J.A. Maffei for example built the 4-6-2 steamturbine locomotive T18 002 with Ljungstoem drive train. The loco delivered 2000 HP and reached a maximum speed of 120 km/h. Deutsche Reichsbahn-Gesellschaft DRG used the loco for fast passenger trains till it had been damaged during WW II. Even the most successful steam more…

To standardize steam locomotives, the Engere Locomotive Standards Committee (ELNA) was founded in 1917. In addition to the framework conditions for the Einheitslokomotiven of the Deutsche Reichsbahn-Gesellschaft DRG, the ELNA also laid down principles for steam locomotives of non-state-owned railways. Three types were developed, of which the 1’C and D versions were by far the most common. Many parts could be exchanged for one another. Since frames, water boxes and driver's cabs were not more…

In order to be able to transport heavier freight trains, the Prussian state railway KPEV commissioned the development of a four-coupled tender locomotive in 1911. The experience gained with the larger G10 series was incorporated into the development of the locomotive, initially known as the G8 reinforced design, and so the 1260 hp new design proved to be on a par with its larger sister in many respects and even superior in terms of driving characteristics on winding routes. That's why the KPEV more…

In the early 1900s, several state and private railways attempted to reduce operating costs by using steam railcars on lightly used routes. The design of one of the most successful types was penned by Eugen Kittel. At one end of the vehicle was the standing boiler integrated into the driver's cab, the equipment required to operate it, the coal box and a seat for the conductor. A stoker with control authorization was allowed to drive the steam railcar. At this time, the conductor was in the more…

In the 1890s, the Prussian state railway KPEV purchased two differently designed tank locomotives for mixed passenger and freight service. The experience gained with the two types, grouped together under the T9 series designation, resulted in the design of the 1’C locomotive T9.3 in 1900. More than 2,200 of the 440 hp two-cylinder wet steam locomotive were purchased. The frugal 65 km/h locomotive was satisfactory for branch line passenger and freight trains, but was also suitable for more…

Two-cylinder locomotives were considered easier to drive and relatively undemanding compared to three- or four-cylinder locomotives. Huge numbers of the standard freight train class 50 and the war locomotive 52, which was developed from it, were built, with more than 3,000 and more than 6,200 examples, respectively, running in almost all neighboring countries. It is therefore no surprise that the most-produced tank locomotives, by far the most produced, were the class 64 (520 units) and 86 (774 more…

The first German three-cylinder steam locomotive to be built in large numbers was the Prussian S10.2 (BR 17) in 1914. Among the reasons given were its lower weight compared to the four-cylinder S10.1 and its favorable starting characteristics. The latter also played a role in the choice of a three-cylinder drive for the Prussian P10 (BR 39) passenger locomotive and the G12 (BR 58) freight locomotive. A disadvantage compared to the two-cylinder locomotives was the more difficult maintenance due more…

In 1904, the Federal Council of the German Empire enacted the first railway construction and operating regulations, which permitted express trains with 44 axles if the train consisted of four-axle carriages; 52 axles were permitted when using six-axle carriages. At the same time, more direct connections were created through the operation of through coaches. The basic speed of express trains was to increase from 85 to 90 km/h. Since even new two-cylinder express train locomotives were reaching more…

Most narrow-gauge railways were built and, at least initially, operated by private companies. The state railways usually coded the track gauge in the class designation, and sometimes also the wheel arrangement. The operating number was generally assigned consecutively. With the integration of many railways into the Deutsche Reichsbahn-Gesellschaft (DRG), the class designations, which consisted of letters and numbers (e.g., Tssd, IV k, or Gts 2x 3/3), were standardized and only numbers were more…
