The four-axle freight railcars with the company numbers 10 001 to 10 003 were specially designed vehicles for the Deutsche Reichsbahn for the " express freight service " of the time.
These vehicles, acquired in 1930, were designated as VT 69.9 by the German Federal Railroad from 1949 .
history
Based on the construction of the two-axle railcars with diesel engines of the numbering scheme DR 851 to 852 , these three vehicles were specially developed for express freight traffic. These railcars were asked on 5 and 6 November 1930, the generic name L4vT into service, but none Reichsbahndirektion were assigned, but the Gattungsbezirk Dresden, as the corresponding freight wagons of the German Reichsbahn.
During the Second World War , the 10 003 was used as a mobile ticket issuer.
After the war, the three cars came to the Deutsche Bundesbahn, where they were listed as VT 69 902, VT 69 900 and 69 901. The VT 69 900 and 901 wagons were retired on December 27, 1960, followed by the VT 69 902 on July 18, 1962.
technology
A Maybach 6-cylinder four-stroke diesel engine (G 4a) was used to drive the 21.4 meter long railcar, the power of which was transmitted via a four-speed gearbox to the jackshaft and coupling rod to drive the bogie. As early as 1932, the 111-kilowatt motor was set to 121 kilowatts at a higher rated speed. From 1935/1936, engines with 129 kilowatts (type G 4b) were used. Motors with 155 kilowatts were installed by the Federal Railroad in 1952/54. The service volume and maximum speed of the vehicles varied accordingly.
The water-cooled engines were started with compressed air. The drive was controlled by means of cables.
The car body frame was made of sectional steel and had sheet metal cladding. The frame was riveted from angle profiles and sheet steel. The frames of the bogies were also riveted. The wheelsets ran in plain bearings. The suspension of the wheelsets and the bogies was done by means of leaf springs.
The luggage compartment had an area of 40 square meters and was accessible via two sliding doors on each side.
