TRACK STRESSES AND VEHICLE MOTION AT HIGH SPEEDS

The high speed test runs made with the locomotives E 10 299 and E 10 300 and 8 wheeled track recording cars and passenger cars are described. Extensive measurements were made of the stresses to which the track is subjected at train speeds of 140 to 200 km/h, and of the dynamic wheel loads and lateral pressures against the rail, as well as the effect of these forces on the roadbed. The results of these tests on curved and straight track are given and illustrated by charts. The present usual track structure will suffice for the high speed operation. The minimum radius of curvature should not be under 1890 meters. Continuous welded rail improves the riding qualities in high speed operation. A desirable riding comfort level is attained in the passenger cars at 200 km/h speeds.
