The Ganz BCs motor wagon

Ganz-MÁVAG Works and Engine Works of Budapest, Hungary, initiated the production of motor traction vehicles in Hungary. In 1927 they produced a motor wagon of the MÁV BC mot. series, characteristic for its light construction with two axles and gasoline motor Ganz VI Am C 130 (66 kW / 90 hp).

These motor wagons adopted in 1928 a new, more developed standard diesel-motor Ganz VI JmR 150 (81 kW / 110 hp), and a few years later even better and specially constructed diesel-motor Ganz VI Ja R 135/185 (88 kW / 120 hp). The power of the diesel-motor was now sufficient, and this was the one to be installed into the further motor wagons destined for export, beginning with 1937. The wagons now had three axles and more wagon classes.

The BCs series motor wagons were equipped with mechanic transmission through the cardan onto one driven axle, and the heating was featured with the warm water of the diesel-motor. These wagons were destined for short commuter drives.

Some of the Ganz motor wagons with two or three axles were in service since 1939 in Osijek (Croatia), and soon afterwards four units were destined to Zagreb.

According to the Temporary inventory of passengers' wagons of Zagreb Railway Direction, composed on 1955/02/15, there was one BCs motor wagon no. 430 with two axles, an another three-axle motor wagon BCs no. 507, and additional two non-operated motor wagons with the serial number 120-005 (two-axle) and 130-001 (three-axle) available. The last mark for a two-axle motor wagon was 813-5, and for the three-axle wagons 813-6.

The motor wagons of the series were utilised within Zagreb junction for the transport of workmen and students between Zagreb Central Station — Maksimir Park — Zagreb-Borongaj — Trnava (6 km). After the World war II, they sometimes used to drive all the way long to Sesvete (11 km). All the time before and after the war they were marked in the schedule as local trains Z1, Z2, Z3... (as for Zagreb) until 1967, when they were withdrawn and subsequently written off. Due to such rides with frequent short transporting — or leaps — they were nicknamed »Zec« (Hare) by faithful passengers.
