This creates high rail stresses at bridge end joints and at movable bearings, wh ich must not exceed the prescribed limit values; otherwise, rail breaks, track distortions and bearing damage can occur. For this reason, the joint load-bearing behavior of the tracks and bridge must be calculated and proof of sufficient load-bearing safety must be provided.
