There are several types of rail joints used in steel rail installation, including bolted joints, welded joints, and insulated joints. Bolted joints involve connecting two rail ends with bolts and nuts, allowing for easy removal and replacement. Welded joints, on the other hand, involve permanently joining two rail ends using welding techniques, providing a more durable and seamless connection. Insulated joints are used to isolate sections of rail to prevent the flow of electric current, commonly used in electrified railway systems.
There are three main types of rail joints used in steel rail installation: the butt joint, the fishplate joint, and the insulated joint. The butt joint is a simple connection where the two rail ends are placed next to each other and bolted together. The fishplate joint, also known as the splice joint, involves using a metal plate called a fishplate to connect the two rail ends. This provides additional strength and stability to the joint. Lastly, the insulated joint is used to electrically isolate two sections of rail, typically used in electrified rail systems to prevent unintended electrical currents from flowing between tracks.
There are several types of rail joints used in steel rail installation, including the butt joint, fishplate joint, and insulated joint. The butt joint involves aligning two rail ends and welding them together. The fishplate joint involves using a metal plate, called a fishplate or splice bar, to connect two rail ends by bolting them together. Insulated joints are used to create electrical separation between sections of track, preventing the flow of electric current. These different types of rail joints are chosen based on factors such as track conditions, design requirements, and the need for electrical isolation.
