MOST RECENT DEVELOPMENTS IN THE FIELD OF VERY HIGH SPEEDS IN FRANCE--ELECTRIC TRACTION AND TURBOTRAINS

Railroads are presently operating at speeds of 200-210 km/hr in France and Japan. Recent research shows that commercial trains operating at 250 km/hr are now a certainty, and that speeds of 300 km/hr are possible. This paper describes SNCF's experience in operating and testing such trains. Modifications needed in track structure, rolling stock, engines, electrical current collection, traction, aerodynamics, braking, and wheel-to-rail adhesion are discussed in detail.
