Magnets Drive High Speed Suspension Trains Thru Air
ELEVATED trains whizzing at tremendous speed from city to city, powered solely by electromagnetic lines of force, is the new and startling method of rapid transportation now being developed by German engineers.
A war against friction losses has long been waged by scientists; and this electromagnetic rapid transit project now promises to end the conflict. No wheels are to be used for traction. The cars are drawn forward, in one scheme by powerful electromagnets, in the other by huge solenoids.
Cars on the solenoid railway are to be equipped with giant magnetic rings, as illustrated on the opposite page. Power is switched on to the solenoids automatically as the car progresses by means of photo-electric cells operating at moment beams are intercepted.
Speed of the electromagnet cars is regulated at the central power station by a revolving switch which cuts the magnets in the circuit like electric lights in a display sign. Connections through wireless enables operator to give stop or start signals.
