rail joints Overview
Rail joints, also known as rail welds or rail splices. Rail joints are crucial components in railway tracks where two rail segments meet, playing a significant role in maintaining the continuity and stability of the track system.
types of rail joints
The two common types of rail joints are bolted joints and welded joints. Bolted joints involve connecting two rail ends using bolts, providing flexibility for expansion and contraction. Welded joints, on the other hand, involve permanently joining the rail ends through welding, ensuring a seamless and sturdy connection.
Characteristics of rail joints
The rail joint must tightly secure the two rail ends, keeping them level and in a straight line. It should match the strength and stiffness of the connected rails, allow for rail expansion and contraction, and enable easy rail removal or disconnection without affecting the entire track. The contact surface between the joint bar and rail track should wear gradually, with rail joints adapting to this adjustment.
An ideal rail joint is cost-effective, economical for both setup and maintenance, and durable. It should possess sufficient elasticity to absorb vibrations and shocks while providing resistance to longitudinal forces during acceleration and deceleration, thus reducing the creeping effect.
