EXPERIMENTAL RESULTS OBTAINED ON THE LATERAL PROBLEMS OF THE LONG WELDED RAIL CONTINUOUSLY LAID ON SEVERAL SPANS OF THE BRIDGE WITHOUT BALLAST

To show the lateral stability of continuous welded rail on a bridge, and the character of the lateral load to the bridge as a result of such rail, a test was conducted by the JNR on an actual bridge. The data resulting from this test shows that even though there were no problems resulting from unballasted rail on a bridge, the lateral forces between rail and sleepers varies and may reach a value which is ten times the calculated value. The phenomena is a result of continuous rail laid on a bridge resulting from the high lateral elastic coefficient of the rail supporting system.
