The locomotives of the series 80 were tender - shunting the German National Railroad . The machines were procured as part of the standard steam locomotive program between 1927 and 1929. The last locomotives of the Deutsche Bundesbahn were taken out of service in 1965 and were used as a factory locomotive until 1977. Seven copies have been preserved.
history
With the unification of the German state railways to form the Deutsche Reichsbahn, the railway company had many different types of shunting locomotives. In many cases, outdated mainline locomotives were also used in shunting operations. Due to this large variety of types and the age of the vehicle, economical shunting was not possible. That is why the construction of shunting locomotives was planned from the beginning as part of the program for the construction of standard steam locomotives. The triple-coupled locomotives were given the series number 80 and the quadruple-coupled locomotives the series number 81 .
In order to increase economic efficiency, the locomotives were given a superheater to be able to use superheated steam. Comparisons with the DR class 89.0 built in 1934 , which were built as hot and wet steam locomotives , showed that this decision was correct . Furthermore, during the construction, emphasis was placed on making the boiler as efficient as possible. This made it necessary to save as much weight as necessary in other areas. Therefore, the coupling wheels were designed with a diameter of 1.10 m instead of 1.25 m. Mass savings were also achieved in the cylinders, axles and the engine.
The locomotives were able to pull a 900-ton train on the plain at 45 km / h. With a gradient of 10 ‰ the power was sufficient for a 175 t train at 45 km / h, at 25 ‰ for 140 t at 25 km / h.
The Aktiengesellschaft für Lokomotivbau Hohenzollern delivered 22 machines in 1928 and 1929 with the company numbers 80 001 - 80 005, 80 018 - 80 022 and 80 028 - 80 039. The Union foundry in Königsberg built seven (80 006-80 012), the Maschinenbau R. Wolf Magdeburg-Buckau five (80 013 - 80 017) and the Arnold Jung Lokomotivfabrik also five locomotives (80 023 - 80 027). All were delivered in 1927 or 1928.
The locomotives were used in shunting operations at the main stations in Cologne and Leipzig .
After the Second World War , 21 locomotives remained with the Deutsche Reichsbahn in the GDR (80 001, 003, 004, 006-012, 017-027), and 14 with the Deutsche Bundesbahn (80 005, 013-016, 028-039). Locomotive 80 002 was damaged in the war and was used as a works locomotive in Raw Meiningen after being refurbished .
On the Deutsche Reichsbahn, the locomotives were used exclusively at Leipzig Central Station until 1962/1963. Then they were replaced by diesel locomotives of the class V 75 (later class 107). Many locomotives were then given to repair shops or track construction companies, where they were used as works locomotives . The last locomotives were scrapped in 1981.
Two vehicles from the Reichsbahn locomotives have been preserved. Locomotive 80 009 is privately owned and could only be acquired during the GDR era because a comparable amount of scrap was collected. The 80 023 belongs to the Dresden Transport Museum and is currently on display in the Saxon Railway Museum in Chemnitz.
At the Bundesbahn, the locomotives were also moved from Cologne to other locations. The last locomotive was the 80 031 on April 15, 1964. The machines were taken out of stock by 1965. In 1958 the first locomotive (80 032) was sold to the Ilsede slag recycling company. Nine locomotives (80 013, 014, 016, 029, 030, 036 - 039) were purchased by Klöckner Werke between 1959 and 1962 and used as factory locomotives. The 80 016 came to the Georgsmarienhütten-Eisenbahn in 1962 and was used as No. 3 III until 1965 . The remaining locomotives were used in the Königsborn II / V, III / IV, Werne , Victor and Heinrich-Robert collieries . After the takeover of Klöckner-Werke by Ruhrkohle AG , the locomotives were given the designations D-721 to D-727. RAG decommissioned the last locomotives between 1974 and 1977.
Preserved locomotives
- 80 009 is privately owned in Berlin.
- 80 013 (RAG D-722) was set up in 1974 on a playground in Kamen-Heeren . In 1986 the Paderborn Museum Railway acquired the locomotive. The locomotive has been owned by the German Steam Locomotive Museum in Neuenmarkt-Wirsberg since March 1989 .
- 80 014 (RAG D-721) was acquired by Peter Beet in 1975 for his Steamtown Museum in Carnforth . From 1980 the locomotive was used on the Nene Valley Railway . It was dismantled in 1985 for a general inspection. However, this investigation was not carried out. In 1998 the South German Railway Museum in Heilbronn was able to purchase the locomotive and start refurbishing the locomotive. Due to the long dismantling time, individual parts were lost, so that the reconstruction took until 2004.
- 80 023 is in the Saxon Railway Museum in Chemnitz.
- 80 030 (RAG D-724) was acquired in May 1974 by the German Society for Railway History for the Bochum-Dahlhausen Railway Museum .
- 80 036 (RAG D-725) went to the Netherlands in November 1976 to the museum railway Veluwsche Stoomtrein Maatschappij .
- 80 039 (RAG D-727) was acquired by Hammer Eisenbahnfreunde in May 1978 .
Constructive features
The locomotives had a bar frame with 70 mm thick frame cheeks. The clear width was 930 mm. At both ends of the locomotive, the frame was pulled up to the level of the buffer beam.
The locomotives had a riveted long boiler with a diameter of 1.5 meters and a Schmidt smoke tube superheater . On the kettle sat two domes and the round sandpit in between. The front dome was designed as a dining dome and had an angle grate sludge separator. The boiler was fed by two steam jet pumps. The rear dome had a Schmidt-Wagner wet steam valve regulator as a steam dome. The two Ackermann safety valves, the steam whistle and the air pump inlet valve were located on the steam dome. The fire box was made of copper. The grate had three fields, the rear field was a tilting grate.
The horizontally arranged two-cylinder superheated steam engine on the outside worked on the rearmost wheelset. The external Heusinger control with Winterthur loop had an internal flow and control piston slide with angle valve pressure equalizers.
The landing gear was supported at three points. The suspension was provided by leaf spring packages located under the axle bearings . The spring assemblies of the first two wheel sets were connected by compensating levers. The wheelsets were firmly stored in the frame. When average wheel were Flanges weakened mm to 10th
The machines had a one-chamber Knorr compressed air brake and a throw lever brake . All wheelsets were braked from the front. The two-stage air pump was located to the right of the smoke chamber and the two 400-liter air tanks were arranged across the frame in front of and behind the first set of wheels.
The compressed air-powered sand spreader of the Borsig-Reichsbahn type sanded all wheel sets when driving forwards and backwards.
All parts under steam were lubricated by a Bosch Reichsbahn high-pressure lubrication pump. The locomotive also had a steam turbine generator for electrical lighting and a steam heating device.
The water was housed in two water boxes arranged to the right and left of the long boiler. The boxes reached to the smoke chamber. Another water tank was under the coal box at the far end of the cab. The coal box was drawn in on the right and left to improve the view of the route.
