In the beginning of 1974, the industry, along with the Deutsche Bundesbahn set up a "Community Office" ("Gemeinschaftsbüro") for the development of a train. More than 30 concept variations of a high-speed train were studied, particularly having the costs per person-kilometer in consideration. The selection was then narrowed down to 10 variations, and the initial results were presented in 1975. A test locomotive of power and the capability to reach was also suggested to be built, but was not realised due to cost restrictions. A draft of a train capable of reaching for 200 to 600 passengers was put forth by the company Messerschmitt-Bölkow-Blohm in 1978, but was not realised as well.
