Answer: "Join two rails"

"Fish plates are metal plates that connect rail ends in railway tracks ensuring alignment and stability. Bolted to the rails they maintain track integrity allowing safe train operations. Fish plates accommodate thermal expansion preventing derailments and are critical in railway infrastructure. Their design reflects engineering precision in transportation systems. Understanding their function underscores the importance of robust infrastructure in ensuring efficient and safe rail transport a vital component of global logistics and connectivity."
