Developments in brake types and methods of control effected over the past few years are surveyed. Under the stresses imposed by new high speed (200 km/h) and heavy (up to 8500 hp) trains, tyred wheels have not demonstrated the necessary reliability and monoblock wheels do not withstand the braking heat. Disc brakes with grey cast-iron have shown promise on streamlined trains. Flat wagons are under construction in Germany wherein the disc brake is being incorporated in the wheel assembly. In Belgium and Germany successive, short interval applications of air-operated disc brakes followed by electric resistance brakes are being used on moderate speed (120 km/h) passenger trains. British Railsway liner trains have been equipped with monobloc wheels in which the wheel center forms the brake disc; however, some trouble has been encountered within the past two years speed-controlled air-electromagnetic brakes have enabled much greater deceleration on Rheingold trains (1000 m for 160 km/h) than wheel-and-rail adhesion systems permit. Track speeds of 200 km/h are possible using disc-magnetic rail systems, and the recommended 1-1/4-in. through brake pipe and double-pipe air brake system might provide the control and protection needed at this velocity.
