The DR Class 243 is a universal electric locomotive of the Deutsche Reichsbahn which is used for general rail service. In the Deutsche Bahn AG the locomotive is listed as Class 143.The locomotives of classes 143/243 still belong to the most successful class of German electric locomotives.
[edit] Development
Since 1980 the Deutsche Reichsbahn of the GDR started increasing track electrification due to the risen oil price. Before that the DR had mainly used locomotives driven by Russian diesel fuel. VEB Lokomotivbau und Elektrotechnische Werke Hennigsdorf, the only manufacturer of electric locomotives in the GDR, received the order to develop, based on the heavy cargo locomotive DR Class 250, a lighter, four-axle and technical more modern one for passenger transport and medium cargo service. The mechanical components were developed and produced in Hennigsdorf. The electric motors were manufactured by EMW Dresden.
The pre-series 212 001 was built in 1982 and presented to the public in the same year with a designed maximum speed of 140 kilometres per hour (87 mph). It did several testing before it was modified in order to operate at a maximum speed of 120 km/h (75 mph) with also changing the number to 243 001. Because of its special painting, 243 001 also has the prename Weiße Lady. The production of the series was started in 1985 after the testing with 243 001 was successfull.
