The DRB Class 42 [note 1] was a type of steam locomotive produced for the Deutsche Reichsbahn. It is one of the three main classes of the so-called war locomotives ( Kriegslokomotiven ), the other two being class 50 and 52.

Contents

Seventy of the class were captured during World War II by the Soviet Union; under Russian ownership they were given the classification TL (ТЛ). [1]

History

These engines, built from 1943 onwards, were the second heavy locomotive class of this type after the DRG Class 52. They were built for duties on routes that were cleared for a higher axle load, because they were more economical there than the KDL 1 Kriegslokomotiven of Class 52. In principle they were slimmed down 44s. The Class 42 was procured as Kriegslokomotive KDL 3.

The total of 859 units had a number of improvements to the driving and running gear. Originally it was intended to build very large numbers of these engines, but the end of the Second World War put paid to that. A condenser locomotive, based on the Class 42 was also planned, but did not come to fruition.

At the end of the war there were still half-finished engines in the workshops. So after 1945, 16 engines were built for the Reichsbahn in the western zone by the Maschinenfabrik Esslingen ('Esslingen Locomotive Works'). 126 engines were built by Polish factories for the PKP in Poland as Class Ty43 and three ex DRG engines also went over to the PKP as Class Ty3. Another 76 units were produced by the Lokomotivfabrik Floridsdorf in Vienna. These were not built for the Austrian Federal Railways (ÖBB), but were sold in 1949 to the CFL in Luxembourg - 20 engines (CFL class 55), in 1952 to Bulgarian State Railways (BDZ) - 33 pcs (BDZ class 16). and the rest to DR and various industrial enterprises in East Germany.

The majority of the locomotives that ended up in the Deutsche Bundesbahn were stationed in the Saarland. These were taken out of service by 1960. The engines with the DR continued to work until 1968, and these with BDZ until 1988. Nowadays (2015) there are only two engines in operation - CFL 5519 and BDZ 16.27 (in service since April 2015). They are used for special and tourist trains. Another operational BDZ engine 16.01 is retired since 2013.

The DB and DR locomotives had operating numbers 42 001–2810 and 42 5000. However they did not run consecutively and there were gaps.

The engines were mainly equipped with 2'2' T 30 or 2'2' T 32 tenders.

DB Class 42.90 (Franco-Crosti locomotive)

In 1952, the firm of Henschel rebuilt locomotives 52 893 and 52 894 with Franco-Crosti economisers (Abgasvorwärmer). Because of the resulting higher axle load, the engines were classified by the Deutsche Bundesbahn as Class 42.90 locomotives and given the operating numbers 42 9000 and 42 9001.

Engine number 42 9000 was stabled in Bingerbrück and retired in 1959. In 1960 the second one, stationed in Oberlahnstein, was taken out of service. The experience accumulated with these very economical locomotives was used in the 31 engines of Class 50.40.

Both locomotives were coupled with 2'2' T 30 tenders.

Notes

  1. Wartime locomotives classes are prefixed DRB (Deutsche Reichsbahn) to distinguish them from those introduced by the DRG (prefixed DRG), which became defunct in 1937, and those introduced later by the East German Deutsche Reichsbahn (prefixed DR).

The Deutsche Reichsbahn's Class 52 is a German steam locomotive built in large numbers during the Second World War. It was the most produced type of the so-called Kriegslokomotiven or Kriegsloks. The Class 52 was a wartime development of the pre-war DRG Class 50, using fewer parts and less expensive materials to speed production. They were designed by Richard Wagner who was Chief Engineer of the Central Design Office at the Locomotive Standards Bureau of the DRG. About a dozen classes of locomotive were referred to as Kriegslokomotiven; however, the three main classes were the Class 52, 50 and 42. They were numbered 52 1-52 7794. A total of 20 are preserved in Germany.

<span class="mw-page-title-main">DRB Class 50</span> Class of 3164 German 2-10-0 locomotives

The DRB Class 50 is a German class of 2-10-0 locomotive, built from 1939 as a standard locomotive (Einheitsdampflokomotive) for hauling goods trains. It had one leading axle and five coupled axles and was one of the most successful designs produced for the Deutsche Reichsbahn.

<i>Kriegslokomotive</i> German war locomotives of WWII

Kriegslokomotiven or Kriegsloks were locomotives produced in large numbers during the Second World War under Nazi Germany. Their construction was tailored to the economic circumstances of wartime Germany along with conquered and occupied territories across Europe, taking account of the shortage of materials, the transportation of goods in support of military logistics, ease of maintenance under difficult conditions, resistance to extreme weather, limited life and the need for rapid, cheap mass production. In order to meet these requirements, economic drawbacks such as relatively high fuel consumption had to be accepted. Forced labour was used in the construction of some of the locomotives; German locomotive building firms employed prisoners from concentration camps and foreign, mostly Polish, workers.

<span class="mw-page-title-main">Prussian P 8</span>

The Prussian Class P 8 of the Prussian state railways was a 4-6-0 steam locomotive built from 1906 to 1923 by the Berliner Maschinenbau and twelve other German factories. The design was created by Robert Garbe. It was intended as a successor to the Prussian P 6, which was regarded as unsatisfactory.

<span class="mw-page-title-main">DRG Class 64</span>

The Deutsche Reichsbahn had a standard passenger train tank engine with a wheel arrangement of 1'C1' or 2-6-2 and a low axle load, which was designated in their classification system as the DRG Class 64. The Class 64 was developed from 1926 onwards and it was built between 1928 and 1940. Many German manufacturers contributed to the series.

<span class="mw-page-title-main">DRG Class 86</span>

The DRG Class 86 was a standard goods train tank locomotive with the Deutsche Reichsbahn-Gesellschaft. It was intended for duties on branch lines and was delivered by almost all the locomotive building firms working for the Reichsbahn. From 1942 it was built in a simplified version as a 'transitional war locomotive'. The most obvious changes were the omission of the second side windows in the cab and the solid disc carrying wheels.

<span class="mw-page-title-main">Prussian G 8.1</span>

The Prussian G 8.1 was steam locomotive operated by the Prussian state railways. It was a heavier, stronger development of the G 8 and was initially referred to as a 'strengthened standard class'.

<span class="mw-page-title-main">DRG Class 56.2–8</span>

Between 1934 and 1941 the Deutsche Reichsbahn (DRG) converted a total of 691 former Prussian-built Class 55.25–56 steam locomotives; the result was the DRG Class 56.2–8. The carrying axle enabled higher speeds and the engine could even be used as a passenger train locomotive. In addition the average axle load was lower, so that these locomotives could also be used on branch lines. The conversion entailed moving the boiler forward and raising it somewhat. The vehicles were given operating numbers between 56 201 and 56 891, although the numbering was not continuous.

<span class="mw-page-title-main">Prussian G 10</span>

The Prussian G 10 was a German goods train, steam locomotive, whose design was based on a combination of the running and valve gear from the Prussian T 16 and the boiler from the Prussian P 8. In developing the G 10, however, the T 16 running gear with side play on the first and fifth axles was modified. The T 16 was also subsequently built with this modified configuration and called the Prussian T 16.1. The G 10 was intended for heavy goods train duties on main lines, but as a result of its low axle load it could be employed more flexibly than its equally powerful cousin, the Prussian G 8.1. The G 10 was occasionally even used in passenger train service.

The Prussian G 8.2 class of locomotives actually incorporated two different locomotive types: one was the Prussian/Oldenburg G 8.2, for which the Deutsche Reichsbahn subsequently issued follow-on orders; the other was the G 8.2 of the Lübeck-Büchen Railway.

<span class="mw-page-title-main">SNCB Type 26</span>

The NMBS/SNCB Type 26 was a class of 2-10-0 steam locomotives built between 1945 and 1947. Originally commissioned as part of an order for 200 DRB Class 52 Kriegslokomotiven placed by the Deutsche Reichsbahn (DRG) with Belgian locomotive manufacturers in 1943, the 100 members of the Type 26 class were completed for the National Railway Company of Belgium (NMBS/SNCB) following the liberation of Belgium late in 1944.
