fish plates are used in railway tracks

The fishtail plate closely connects the ends of the two sections of track together through fasteners such as bolts or rivets to form a continuous and smooth track system.

During the running of the train, the fishtail plate can withstand the huge impact of the train to ensure that the track will not be displaced or deformed, thereby maintaining the stability of the track.

Because the railway track will expand and contract when the temperature changes, the design of the fishplate allows the track to expand and expand within a certain range to avoid track damage due to temperature changes.
