The railcars 137 000-024, 036-054 and 121-135 belong to a series of railcars that were originally built with 129 kW power for the Deutsche Reichsbahn-Gesellschaft as lightweight railcars with mechanical transmissions .
history
Reichsbahn time
In principle, the DR 853… 871 (heavy-duty four-axle diesel multiple units) had proven themselves well in service at the time. In order to be able to operate at 80 km / h on main lines, the company Waggon- und Maschinenbau received the order to revise the vehicle part of the heavy railcars. By exhausting all the possibilities of lightweight construction while maintaining the Wismar-Maybach drive concept , a vehicle was created in 1932 with a specific drive power of 3.6 kW / t, a considerable improvement over the DR 853 ... 871 . In addition to the railcars, there were 25 four-axle sidecars adapted to the layout in the same design, which were classified as VB 147 004 to VB 147 028. This vehicle composition determined the image of the modern Reichsbahn on branch lines in the 1930s. The first vehicles delivered in 1932 were still delivered with the old railcar designations 862 to 864 and 875 to 876 . It was not until October 1932 that they were included in the new designation from 137,000 .
The vehicles were manufactured in several lots by several companies up until 1935. The railcars from 137 036 were redesigned and lighter, the drive frame was extended to 3,800 mm. Based on the Eva Maybach concept, they ran with the T2 mechanical transmission from Maybach-Motorenbau . This is a five-speed vehicle transmission. The diesel engine was switched off when it came to a standstill. The engine was started with compressed air while first gear was engaged, so the railcar started when the engine was started. The concept was later improved in that the engine could be started when it was at a standstill and the gears could be engaged using a friction clutch. The individual gears were secured against overturning with a centrifugal governor; the gear was automatically disengaged when a critical speed was exceeded.
The drive took place on a jackshaft, the two axles of the drive frame were driven by coupling rods. The running bogie corresponded to the type Görlitz IV slightly, it was still riveted. The welded car body was made in frame construction, the side walls were used for support. The side walls were drawn in at the entrances, the head shape rounded.
After the vehicles were accepted, they were used by many Reichsbahndirections in passenger train operations, where they proved themselves quite well. At that time there were still several problems with the diesel engine, e.g. B. the expansion-free power of the engine fluctuated between 2,000 km and 166,000 km. When the war began, the vehicles were initially shut down. Many railcars were restored as Wehrmacht vehicles. Few vehicles survived the war.
Post war era
German Federal Railroad
The Deutsche Bundesbahn took over the 137 021 and 137 008 from the first delivery series, initially as VT 65 916 and VT 65 917, later as VT 62 905 and VT 62 906 and used them on various branch lines.
Of the railcars with 155 kW system, the DB only took over the 137 127 as VT 62 902 and renamed it. Soon all three were moved together in Bremen. From 1952 they were deployed from Braunschweig. There were three VB 147 railcars in Braunschweig, which also came from Bremen. By 1958 the end came for all three railcars at Braunschweig Hbf. The sidecars were used together with other railcars until 1962.
German Reichsbahn
With the Deutsche Reichsbahn in the GDR, the 137 005–007, 012 and 013 from the first series remained, from the second series 137 044, 122, 132, of which only the latter two were restored. As before the war, they were based in the Dresden-Pieschen depot and the Cottbus RBD . Noteworthy are the operations in the branch line service on the Mandautalbahn , where the VT 137 005 and 007 were in service until 1961 and were then retired. A sidecar has survived to this day and is now in the Dessau Railcar Museum .
Norwegian State Railways
The five railcars 137 041, 123, 124, 134 and 135 came to Norway during the Second World War. After the end of the war they stayed there and were taken over by Norges Statsbaner in 1945 under the series Cmdo type 8a , numbers 18290 to 294 . In 1946 the division into the series Cmdo type 9a took place , on December 17, 1953 the former railcars 041, 123 and 135 were retired. In 1956 the former 137 124 followed and the former 134 was taken out of service in 1958.
One of the diesel-mechanical railcars with 155 kW power has not survived. They represented a valuable development step for the development of diesel-mechanical railcars with automatic transmission. It is questionable whether a drive head of a four-axle diesel railcar with mechanical power transmission was intended for the exhibition in the Dresden Transport Museum in 1970 , but this never happened. It is unclear whether this drive head was a class DR 137 000… 135 railcar or the 856 , which ran in Bitterfeld until 1960 .
