Various changes, especially to the WC units, later led to several sub-types. The first track on which the new cars were used was the Leipzig - Chemnitz line, declared a regional express train (RegionalSchnellBahn, or RSB). The locomotive used here was the BR 232. Because of the progressive decommissionings of the DR and replacements by railcars, the cars were also used in states of former West Germany. For use in push-pull trains with locomotives without ZWS, some received the 36-pole control line from the old DB pushpull control cars. Most, however, went into operation with the control cars converted in 1995 from Bybdzf 482 into push-pull service with ZWS. In the former DR region, the BR 112, 143, 219 and 234 were especially used in this capacity. By now, most cars have been scrapped or sold. Many were taken over by Hungarian State Railways. Eisenach - Hall is one of the last lines in the DB in which the 'langer Halberstadter' are used.
