TRACK LOADING FUNDAMENTALS--4 CURVED TRACK AND LATERAL STRENGTH

Various factors affecting the design of curves are examined. These include ballast depth, flange forces exerted on curves, lateral strength of curved track, and track slewing. It is pointed out that the lateral strength of track depend chiefly on sleeper spacing, quality and depth of ballast and quality of roadbed. Track slewing can be retarded by using heavier rail to maintain alignment, laying stone ballast, reducing sleeper spacing, or by using metal sleepers selectively on curves.
