Light metal car
As a light alloy car rail vehicles are designated with an aluminum - car body are fitted. This enables additional weight savings compared to the lightweight steel wagon.
history
The construction of light metal wagons began towards the end of the Second World War at the Schweizerische Industriegesellschaft (SIG), which had received an order from the SBB to build the lightest possible passenger car for the Brünigbahn, its only narrow-gauge line, which also had rack and pinion sections. This was achieved with an independent shell construction in which the substructure, walls and roof form a unit. A car weighed 13 to 14 tons. A luggage railcar could thus transport four instead of three four-axle vehicles over the rack ramp. In another series, which went into operation in 1954, the weight could be reduced by a ton. SIG and SBB had already gained their first experience with aluminum in 1939 when a viewing car with a central entrance was built. This had a steel frame with fish belly supports on which the box made of aluminum and glass was placed. So it was not yet a self-supporting structure. The Schweizerische Waggonsfabrik Schlieren proceeded in a similar way with the construction of standard-gauge branch line wagons for the SBB, which came into operation from 1947. Due to the prevailing shortage of materials, the underframes with trusses were constructed from old material from broken-down wagons; an aluminum box was placed on top. This resulted in a car weight of only 20 tons.
Switzerland
- Light metal wagon type "Seetal" (1947) of the SBB and the PBr
- Standard car I (1962) SBB B 8201 to 8203, later RHB B 10 and 11 and GFM B 363
- Standard car III (1975) of the SBB, today BLS
- IC2000 (1996)
- Many narrow-gauge center entry cars and standard cars are also made of aluminum.
Germany
In addition to passenger carriages, S-Bahn and U-Bahn wagons also received car bodies made of aluminum, e.g. B. the series A3L ( West Berlin , 1966) and G ( East Berlin , 1974) of the Berlin subway .
France
