What is the function of the railfish plate?

 

A rail fish plate (or splice bar) joins two rail ends, providing structural integrity by keeping them aligned, maintaining the correct height and gauge, and transferring wheel loads smoothly across the joint for safe, continuous train passage, preventing misalignment and deflection. They are essential for track stability and signal continuity, using bolts to secure the rails together, and can be specialized (e.g., insulated) for electrical isolation.
