Development
Beginning in 1976, the Deutsche Reichsbahn of the GDR recommenced their railway electrification efforts in the wake of the 1973 oil crisis, which had also affected the East Bloc countries. Prior to this, Deutsche Reichsbahn had mainly acquired Russian-built diesel locomotives, such as the class 120 and the DR Class 130 family, as the Soviet Union had been providing the GDR with inexpensive heavy oil and diesel fuel. VEB Lokomotivbau und Elektrotechnische Werke Hennigsdorf, the only manufacturer of electric locomotives left in the GDR, was subsequently ordered to develop a modern lightweight, eight-wheel electric locomotive for both passenger and medium freight services, which was to be based on the heavy DR Class 250 Co'Co' freight locomotives. The bodywork and other mechanical components were developed and built at LEW's Hennigsdorf works, while the traction motors and other electric equipment were manufactured by EMW Dresden and various other producers.
The prototype for this new locomotive type was designated 212 001. It was built in 1982 and first presented at the Leipzig Spring Fair that year. As built, the locomotive was capable of a maximum speed of 140 kilometres per hour (87 mph). It underwent extensive route trials before being disassembled for evaluation purposes, and while being reassembled was modified for a lower top speed of 120 km/h (75 mph), which had been specified for all following production locomotives. At this time, the locomotive was redesignated 243 001. Owing to its special livery of white with crimson stripes, 243 001 was given the nickname Weiße Lady (White Lady). Production of the new class began in 1985 after 243 001 had proven satisfactory during her trial period.

Famous quotes containing the word development:
“Dissonance between family and school, therefore, is not only inevitable in a changing society; it also helps to make children more malleable and responsive to a changing world. By the same token, one could say that absolute homogeneity between family and school would reflect a static, authoritarian society and discourage creative, adaptive development in children.”
—Sara Lawrence Lightfoot (20th century)
“For decades child development experts have erroneously directed parents to sing with one voice, a unison chorus of values, politics, disciplinary and loving styles. But duets have greater harmonic possibilities and are more interesting to listen to, so long as cacophony or dissonance remains at acceptable levels.”
—Kyle D. Pruett (20th century)
“I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.”
—Benjamin Harrison (1833–1901)
