What is fish plate?

A fish plate, also known as a joint bar, splice bar, or angle bar, is a metal plate that is used to connect and strengthen two sections of railroad track. Fish plates are typically made of steel and are bolted to the sides of the track, joining two rails together to maintain the correct gauge and alignment of the track.

Fish plates are commonly used in railway maintenance and repair to replace damaged or worn-out rail sections, or to join new sections of track together. They are also used in the construction of railway tracks to create smooth and continuous running surfaces for trains.

Fish plates come in various sizes and designs to suit different rail profiles and track configurations. They are an essential component of railway infrastructure and play a critical role in ensuring the safe and efficient operation of trains.
