The tank locomotives of the 64 series with a 1'C1 ' wheel arrangement were procured by the Deutsche Reichsbahn for passenger trains on branch lines . They were built as standard steam locomotives with an axle load of 15 t. Production took place between 1928 and 1940. Numerous locomotive factories from Germany took part in its construction. The class 64 is technically largely identical to the class 24 , which thus represents the variant of the class 64 with a tender and was intended for longer routes.

development

When the Deutsche Reichsbahn was founded in 1920, mostly obsolete locomotives were running on the branch lines, which had to be replaced. The different spare parts of the individual types of earlier German state railways ("Länderbahnen") also drove up the maintenance costs. Therefore, as early as 1920, drafts for a triple-coupled , modern superheated steam tender locomotive with a running axle at the front and rear were made. With a top speed of 90 km / h, this should also be suitable for light trains on main lines. Those in charge of the Reichsbahn already saw the burgeoning competition from road traffic. This led to the decision in September 1924 to develop the planned tank locomotive after express and freight locomotives for main lines had previously been worked through with the 01 and 44 series . The new locomotives were also to have parts that were standardized with other series. At the eighth meeting of the select committee for locomotives on March 26 and 27, 1925 in Munich, there was no agreement on whether a tank locomotive or a steam locomotive with a tender was more suitable for passenger trains on branch lines. The design department head Richard Paul Wagner favored a tender locomotive instead of the tank locomotive. In addition, the Reichsbahn-Zentralamt had asked the management whether a tank locomotive or a locomotive with a tender was required. The tender locomotive was preferred for East Prussia , but the Frankfurt Directorate wanted to procure tender locomotives. Ultimately, during the consultation in Munich, it was decided to work through the class 64 tank locomotive and the largely identical class 24 locomotive with a tender. Together with the class 86 , a four-fold coupled tank locomotive with running axles at the front and rear, these three steam locomotives initially formed the series of standard locomotives for 15 t axle load. In 1934, this series was supplemented by the double-coupled tank locomotives of the 71.0 series . These also had running axles at the front and rear.

technology

With the exception of ten copies, which had a Krauss-Helmholtz frame , they had Bissel frames . The vehicles from road number 64 368 were 10 cm longer than the previous ones.

history

The first machine arrived at Raw Kassel on January 12, 1928, and just five days later it made its first test drive from Kassel to Treysa . A total of 520 locomotives have been built. Of these, 188 locomotives (= 36%) were put into service as early as 1928. However, the smaller manufacturers Vulcan, Humboldt and Hagans gave up all locomotive construction as early as 1928. Humboldt's delivery quota was initially taken over by Hohenzollern and passed on to Krupp in 1929, without Hohenzollern producing a class 64 locomotive. There were further upheavals in the wake of the global economic crisis . In 1929, the Königsberger Union foundry finished building locomotives. Linke-Hofmann, AEG and Borsig only produced class 64 locomotives in 1928, but they continued to produce rail vehicles. In a similar way, Schichau only produced the 64 series until 1929 and then continued to build locomotives. Hanomag, however, stopped building locomotives at the end of 1930. This was completely taken over by Henschel. As a result, from the delivery year 1931 onwards, Esslingen, Jung, Krauss-Maffei, Krupp and Orenstein & Koppel were only five of the initially 15 manufacturers involved in the 64 series. In 1940, the last year of construction, there were only Esslingen, Jung and Orenstein & Koppel. In favor of freight locomotives, which were more important during World War II, 40 locomotives ordered from Jung and 50 from Orenstein & Koppel were canceled. The locomotive built by Orenstein & Koppel in 1940 with the serial number 13300, which was planned as 64 493, was delivered directly to the Elmshorn-Barmstedt-Oldesloer Eisenbahn (EBOE) and went into operation as locomotive number 11. Otherwise all locomotives came to the Reichsbahn. The highest number assigned was 64 520.

In addition to passenger train service, the series was also used in express train service. After the Second World War , 393 vehicles were left, of which 278 went to the Deutsche Bundesbahn and 115 to the Deutsche Reichsbahn . The 64 311 remained in Austria after 1945 and formed the series 64 at the ÖBB . The copies that remained in Poland were given the designation OKl2 by the PKP , while the locomotives in the ČSR, the former Sudetenland, received the series 365.4 from the ČSD , some with the Soviet SŽD class ТУ locomotives. At the end of 1945 the Reichsbahn handed over 64 511 to the Brandenburgische Städtebahn . After its nationalization, the locomotive was given the number 64 6576 when it returned to the Reichsbahn. It did not get its old number again until 1957. On February 16, 1963, the Bundesbahn decommissioned 64 246 at the Nürnberg Hbf depot and then sold it to the Ilmebahn . She put this back into operation as number 8. In 1968 the Bundesbahn still had 60 machines. The last 30 machines were in service at the Aschaffenburg, Tübingen and Weiden depots until the 1970s. The last Deutsche Reichsbahn locomotive was retired in 1974.
