THE STABILITY OF TRACKS LAID WITH LONG WELDED RAILS

A study of the behavior of track under traffic situation. Factors considered are axle loading, pliability of the formation, mechanical characteristic of the rail, temperature, type of sleepers and fastenings. Included is a study of the deformation of the track in its plane which initiates a differential equation of variable and non-linear coefficients. Recommendations for the requirements of 250 km/h plus 300 km/h systems are included at the end.
