The investigation of eddy-current and magnetic rail brake structures is described. Comparisons on experimental
and computed operating characteristics of eddy-current and magnetic rail brakes for use on a tram-car, on a railroad vehicle,
and on a high-speed train are presented. It is demonstrated that a brake built up from permanent magnet pieces that
combines both magnetic rail brake and eddy-current brake permits of the most profitable braking action through the whole
range of acceptable speeds – from zero (a parking brake) to 350 km/hr.
