THE METRO AT ATLANTA
LE METRO D'ATLANTA
The Metropolitan Atlanta Rapid Transit Authority (MARTA) has ordered 100 coaches for the metro lines now being built in Atlanta, capital of Georgia (USA), from the "Societe Franco-Belge de materiel de Chemin de fer" (Franco-Belgian Railway Rolling Stock Company). Delivery will commence in June 1978 and the rolling stock is designed to meet specifications and requirements that are quite different from those generally encountered in Western Europe. The body of the coaches is similar in many respects to that of the MF77 Series of the Paris Transport Authority (RATP) and their common origins are obvious. They have an integral body and chassis without framework of sheet metalwork. The sides, underframe and roof consist of extruded aluminum sections welded together. The electrical equipment, supplied by Garrett and designed for the 750 V 3rd rail system, includes two direct-current traction motors on each bogie. The traction motor speed is controlled by thyristor chopper equipment. A dual braking system is provided using electric regenerative brakes and pneumatic friction brakes.
