Since the railcar industry in the DDR was fully occupied with export orders, Halberstadt RAW was the only shop available for the construction of the new car. Because the facilities there had been expanded by this time, the new vehicle could now fully exploit the UIC measure of 26.4 m. There was a prototype as early as 1973, and a second followed in 1975. Both were tested extensively in daily operations. The name "Langer Halberstädter" was coined rather quickly in common parlance, making a connection with the famous sausages produced there.
