Prototype: More than 6,145 express train cars of the Deutsche Bundesbahn are designated as UIC-X cars, which were put into service from 1952 and sometimes ran in express trains and in intercity traffic for half a century. These cars had a level of comfort that was previously unknown in Europe. The UIC-X cars were immediately put into high-quality express train use, especially in international services and in transit and inter-zone traffic to West Berlin and the GDR, these cars quickly became the standard. The existing F-train network (until 1956 with the then first and second carriage class, after that only the first) was converted to UIC carriages very quickly. By the mid-1960s, this car design had ousted practically all pre-war cars from express train service.
