The BVG Class A3 was a type of Kleinprofil train that was built after World War II. The smallest operationally mobile unit is the double-rail car, which consists of a control car (S-car) with a straight carriage number and a compressor car (K-car) with an odd car number. Both vehicles are motorized and each is equipped with a cab, the term "control car" refers to the local facilities for electrical control. The K-wagon contains the compressed air system, the converter system and the lighting equipment. The numbering was carried out by car 999/998 backwards, which 999/998 is the oldest A3 unit. Until the late 1970s, the K-car was reserved for non-smokers, whereas the S-car was allowed to smoke.[citation needed]
