The Requirements Of Qulified Rail Joint
Strength and Stiffness: The joint must be robust and rigid, ensuring it provides the same strength as the original track section.
Cost-effectiveness and Durability: The joint should be inexpensive to procure and maintain while offering long-lasting durability.
Level Surface: It must ensure a continuous and level surface for the smooth movement of trains.
Gauge Maintenance: The joint should preserve the gauge distance of the track, preventing any deviation.
Prevention of Rail End Damage: It should prevent the rail ends from being battered or damaged under any circumstances.
Level Rail Alignment: The joint must maintain both rails at the same level to ensure seamless train operations.
Allowance for Expansion and Contraction: It should facilitate the free expansion and contraction of rails due to temperature fluctuations.
Easy Removal and Replacement: The joint should allow for the straightforward removal and replacement of rails without disturbing the entire track.
Lateral and Vertical Elasticity: The joint should possess elasticity both laterally and vertically to absorb shocks and vibrations, ensuring stability and safety.
