Between 1913 and 1917 the French state railway company ÉTAT purchased 340 copies of the 1’D 140 C steam locomotive. After the beginning of the First World War, production was outsourced to British manufacturers. A third series of 70 machines was ordered for the transport of French artillery trains and after the War sold in equal parts to the French Eastern Railway EST and the PLM. The locomotives intended for freight train service developed 1210 hp and achieved an impressive 70 km/h for a more…

In the 1950s Deutsche Reichsbahn DR of GDR needed a high-speed locomotive to test new passenger cars. The testing department of DR developed the 18 201 out of tank loco 61 002, a new boiler (out of “Reko” re-design programme) and the cylinders of a test loco. The loco develops 1590 HP and reaches a maximum speed of 176 km/h. 18 201 is the fastest operable steam locomotive in the world.

Two-cylinder locomotives were considered easier to drive and relatively undemanding compared to three- or four-cylinder locomotives. With the nationalization of the numerous privately financed railways in the 1880s, Prussia favored such locomotives because they could be repaired "in an East Prussian cowshed if necessary." It's no wonder, then, that two-cylinder locomotives accounted by far the largest production numbers. The G8.1 freight locomotive (BR 55.25-56), almost 5,000 of which were more…

In 1935, the Deutsche Reichsbahn-Gesellschaft DRG acquired the streamlined 61 001 to haul the famous Henschel-Wegmann train. The two-cylinder locomotive had an output of 1450 hp and reached a speed of 175 km/h. After the Second World War, the one-off remained with the DB, which used it to pull express trains after dismantling the engine cover before it suffered damage in 1951. As the DB no longer wanted to finance repairs to the locomotive, the machine was taken out of service in 1952, but was more…

In 1939, the Deutsche Reichsbahn-Gesellschaft DRG purchased the streamlined 62 002 for the Henschel-Wegmann train. The three-cylinder locomotive produced 1450 hp and reached 175 km/h. It differs from its sister locomotive 61 001, built four years earlier, for example in its three-axle bogie below the coal box and its three-cylinder engine. After the Second World War, the one-off remained with the DR and was used until 1958. The DR used parts of its chassis and engine to build the 18 201 for the more…

After the Second World War, the Deutsche Reichsbahn DR had 65 Class 01 locomotives. At the end of the 1950s, the DR included the indispensable 01 in its reconstruction program and from 1961 onwards equipped a total of 35 machines with new boilers, new pumps and, for the most part, new cylinders. By 1966, the majority of the 2240 hp, 130 km/h 01.5s had also been fitted with oil main firing, which made the powerful and reliable three-coupler very popular with the staff. It was only after the more…

The Deutsche Reichsbahn-Gesellschaft had the class 03 developed to supplement the heavy express train locomotive 01, which was designed for operation on well-developed main lines. Between 1930 and 1937, 298 examples of the 1980 hp two-cylinder locomotive with a top speed of 130 km/h were built. In front of light and medium-heavy passenger trains, the three-couplers impressed with their good driving characteristics, but in many DB departments in the 1950s the travel times of the express trains more…

Due to the lack of heavy express train steam locomotives of the 01 series, the 03, which was less suitable for these services, had to step in in the 1950s and 1960s. Since the locomotives were still quite new in the 1950s and in good general condition, the DR decided not to reconstruct them. However, after the very new boilers of the 22 decommissioned (reconstructed BR 39, ex. pr. P10) were available from 1969, 52 old building 03s were equipped with these Reko boilers. At this point, the DR's more…

In 1949 the Deutsche Bundesbahn had ordered 105 locos of Class 23 steam locomotives to replace old-fashioned Prussian P8 locos. The 2 cylinder locos developed 1785 HP and reached a maximum speed of 110 km/h. They were used for passenger service, sometimes also for fast trains. Last 23 quitted service in 1975, but eight locos can be found at railroad museums in Germany and the Nederlands.
