In 1973, the Bundesbahn procured only three sets of a four-car high-speed train, which reached 200 km/h and was used as Intercity. The technology was based on the S-Bahn trains of the class 420 and here too all axles were powered. The problematic tilting mechanism soon had to be deactivated and their use as an Intercity ended in 1979. Between 1982 and 1993 they were used as the “Lufthansa Airport Express” between the Düsseldorf and Frankfurt airports in order to reduce domestic flights.
