To join the meeting ends of the individual lengths of rail accurately together while allowing for expansion & contraction with temperature changes.
In many places fishplates have been superseded for very long stretches of track by welds, creating "continuously welded rail"; with suitable expansion-joints at intervals. This gives very smooth, relatively quiet running even at 100+mph.
