Modern drive engineering in electric railroads is characterized today by the use of power electronics. Two systems are available for vehicles in rapid transit systems - such as streetcars, municipal railroads and subways - which are all DC operated: 1. DC chopper control system, in which conventional traction motors of DC series-wound design are controlled by DC chopper, and 2. Three-phase systems in which the traction motor is a three-phase induction machine with a squirrel-cage rotor, fed by a current source DC link converter. The DC chopper system is already in wide use today in rapid transit vehicles, whereas three-phase traction motors are only now coming into service in the first series-produced vehicles. The present paper deals with the circuit arrangements, furnishes data on the reliability of the equipment, and comments on their compatibility with communications and signalling equipment.
