Starting in 1952, the Deutsche Bundesbahn put the express train coaches known as UIC-X into service. The coaches offered an unmatched comfort never seen in Europe before. The UIC-X coaches immediately entered the high-quality express train service. Very soon, the existing F-train network, with its until 1956 first and second class service (but later only the first class service), was supplied with UIC coaches.
