Magyar Automobil Rt Westinghouse-rendszer (Hungarian Automobile Ltd Westinghouse-system) was set up in 1908 in the city of Arad. It was using licence from the French subsidiary of Westinghouse and the French company even had a stake in the factory. There is precious little known about the early history of the factory until 1911 when it went bankrupt. There were probably a few dozen vehicles built, including the truck pictured using French parts. In 1911 the factory went bankrupt and was saved by a Hungarian rubber company. It was renamed to MARTA (Magyar Automobil Rt Arad - Hungarian Automobile Ltd Arad). Westinghouse was out. Trucks became the mainstay of the company, licence of a 5 ton chassis from Daimler was bought in Germany. Passenger cars were also built based on the old Westinghouse design.
There are many, many myths surrounding this company, including a very recent project by the mayor's office in Arad building a modern recreation of a double-decker bus which was "made in Hungary" - in reality the bus was made in France by Westinghouse and supplied to Arad before the Hungarian factory was completed.
