STRESSES IN THE RAILS, THE BALLAST AND IN THE FORMATION RESULTING FROM TRAFFIC LOADS. STRESSES IN RAILS
This report describes measurements taken by the DB and SNCF with a view to studying the dynamic stresses in rails. Measurements were taken on a number of tracks with varying subgrade conditions and track structures. Forces of vehicles, including locomotives, operating at up to 200 km/h were measured. The report is in four parts. Part 1 defines the purpose of the measurements, the places they were taken, the quantities which were measured, and summarizes the principal results obtained. Part 2 describes the measuring and calibration methods. Part 3 reports the measurements taken by SNCF. Part 4 reports the measurements taken by DB. Data yields stress in rail under the effects of vertical and horizontal forces. Observations are made on importance of voids under ties, rapid increase in dynamic forces from lateral track misalignment, flexibility of vehicle suspensions, curve radius, track design and train speeds.
