IMPROVING HEAT DISSIPATION WITH EDDY-CURRENT BRAKING

The eddy-current brake developed by French National Railways has been redesigned to reduce the high temperatures produced by deceleration from very high speeds. A coil with increased air gap in non-critical areas makes this possible. A configuration which would produce eddy currents in wheels or braking discs as well as in the rail could reduce the thermal load in the rail itself where track buckling might result from passage of frequent trains being braked.
