Tehran Wagon Manufacturing Co. (TWM Co.) was established as an Irano-Chinese joint-venture for the purposes of manufacturing metro and double-deck cars, in February 2004.
The TWM Factory was constructed on a parcel of land measuring 100,000. Sq.m in area, located at the Jafar-Abad District in southern Tehran. During the first phase, 29,000. Sq.m of saloons required for assembly ofdouble-deck and metro cars were constructed in 2006.
Subsequently, the saloon and other buildings required for manufacturing of double-deck car-bodies were constructed with a floor-area of 21,000. Sq. meters.
Car-body Manufacturing Hall
The facilities required for manufacturing of double-deck car-body structures, together with those needed for manufacturing of carbon-steel and Al-alloy metro car-body structures are available and any of the above-mentioned car-body structures can be manufactured as per the orders placed by the Customers.
The Components Manufacturing Workshop, located at the north-western wing of the Manufacturing Hall is equipped with all necessary machinery and is capable of manufacturing more than 400 wagon-related metal parts, including, battery-boxes, air-conditioning system cases, ducts of A/C system; blocks to be placed at the floors of the Al-alloy cars and on-board lighting equipment of the cars.
