THE RAIL MOTOR-BRAKE

Achieving train speeds of 300 to 400 KMH are discussed. Over 200 km/h no conventional technical solution is suitable as to the fundamental aspects of traction, and mainly the braking. The rail would become an integral part of the electric motor, propulsion and braking systems regenerating linearly, rapidly and indefinitely under the field part of the motor, of which it becomes, electrically, the armature. The motor or braking effort, the system being reversible, hence are produced between the rail head, wherein flows induced currents producing the effort. A magnetic core, provided with windings, constitutes this part of the motor which provides the inductor field necessary for propulsion, asynchronous sliding field, by its feed with variable frequency, polyphase, alternating current. This motive power unit would employ classical railway, yet would be independent of traction adhesion and braking limits.
