Of the railcars in the British zone, some were refurbished again, the other had to be taken out of service because of war damage. However, this resulted in various spare parts, which ensured a long preservation for the remaining vehicles. In the refurbishment of the railcars, they were given a completely red coat of paint once again, reminiscent of their colour when they were first delivered. Bielefeld was the site of deployment for many years for the vehicles now designated VT 45 502 - 504. From this location, they were used in the 50s for respectable cross-country routes. There was thus a broken connection in the main train station in Kassel to Frankfurt/M.-Bielefeld and the triangular route Bielefeld-Wurzburg, Wurzburg-Hannover, Hannover-Kassel-Bielefeld. After 2 railcars were modernised in 1960, fitted with fluorescent lighting and new seats, among other things, the Bielefeld railcar service was suspended in 1966. Today the former roundhouse of the depot houses a disco which carries the same name. The VT 455 were new to the Braunschweig depot, where they received the EDP-compatible designation 645 102/402 - 645 104/404. In 1969, all were taken out of service and, unfortunately, also disassembled.
