The Deutsche Bundesbahn (DB) promoted the InterCity '79 program with the slogan "Every hour, every class." However, in order to be able to offer every class every hour, the corresponding 2nd class passenger cars with a 200 km/h approval had to be available first. This was achieved by foregoing new developments and instead modifying cars from existing orders of the Bm 234 type or converting cars that had already been completed. Instead of the block brakes and wheel sets of the 094 or 096 type, the cars were now equipped with disc and magnetic rail brakes and wheel sets of the 093 type. To this end, the damping of the bogie cradles was modified and large sway dampers were added to the sides. The new type designation is now Bm 235. In three years, 721 Bm 235 cars were built, which could be used in InterCity service in ocean blue and beige livery from 1979 onwards. Their use in IC and as reinforcement cars in InterRegio service from the 1990s onwards only came to an end in the 2000s. The cars were painted in the typical IC product colors and later in light gray and traffic red. Some cars were even repainted in the current ICE design.
