STRESSES AND BEHAVIOR OF RAIL TRACKS DURING THE PASSAGE OF TRAINS TRAVELLING AT VERY HIGH SPEEDS; STANDARDS ADOPTED BY THE SNCF FOR ITS FUTURE VERY HIGH SPEEDS LINES (250/300 KM/H)

On the Paris-Madrid line in Southwest France, between Bordeaux and Dax, there is a section on which there are two straight stretches of 20 to 45 km, separated by a curve with a radius of 2850 meters. This SNCF line allows tests to be carried out at speeds of over 250 km/h. Since August 1972, two prototype trains, the TGV 001 turbotrain, and the Z 7001 electric motor train, have been traveling four times a day at speeds between 250 and 320 km/h. This paper summarized the knowledge acquired in France as the result of systematic tests carried out at those speeds in anticipation of the new Paris-Sud-Est line on which trains will travel at speeds of over 250 km/h. Although the problems are not yet completely solved, they are at least now defined very clearly, and none of them is of a fundamental type. The doubts raised a few years ago now appear to be baseless, at least for speeds of up to 300 km/h.
