DB "Donnerbüchse" cab car in Oberhausen. A number of these cars were converted for push-pull operation with class 78. The driver was sitting behind a window in the front wall and could brake the train and give commands to the fireman operating the locomotive. It is planned to convert the 78 468 and the cab car so that the push-pull operation becomes possible again. The car shown is not operational as a cab car.
