Basic Knowledge Of Rail Fastener
Aug 07, 2017

The rail fastener is a part of the track used to connect rails and sleepers (or other types of rails), also known as the intermediate coupling part, which is to fix the rails on the sleeper, to maintain the gauge and to prevent the rails from moving vertically and horizontally relative to the sleeper.

It includes spikes, rail under the plate and elastic or rigid withhold parts, etc., fasteners should be able to long-term, effectively maintain the reliable connection between rail and sleeper, and can exert its cushioning and damping performance and delay the accumulation of track remnant deformation under the dynamic action, so it should have sufficient strength, durability and certain elasticity, and should be constructed simply, easy to install and dismantle.
