Rail joints types essentially include bolted rail joints, compromise rail joints and insulated rail joints.
As a professional manufacturer of rail joint bars, we supply almost all the international standards of railway fish plates. Bolted rail joints are used to join two rails in jointed rail territory. In the continuous welded rail (CWR) territory, bolted joints are used to temporarily join rails before they are welded. Compromise rail joint bars are used to join two rails with different sections together. Insulated rail joints are further categorized as bonded or non-bonded rail joints. Bonded insulated rail joints are glued. Non-bonded insulated rail joints are basically bolted joints having some type of electrical insulating properties.
Although the bolted rail joint, compromise rail joint and insulated rail joint perform differently with different operational objectives, they share many similar design features. For example, they all use track bolts and rail joint bars and they all create a discontinuity in the running surface of the rail.
Why Rail Joints Matter? Rail Joints Function
As we all know, rail track bolts gradually fail due to yielding, and rail joint bars usually fail due to fatigue. The discontinuity in the running surface of steel rail creates conditions that can accelerate track degradation around the rail joint. At a minimum, the gap at the rail ends within the rail joint is a source of impact loading from passing wheels. Left unchecked, these impact loads increase rail end batter, thereby deteriorating the foundations, which further increase the impact forces generated by passing wheels.
Rail Joints Maintenance mainly includes 3 types: Surfacing due to ballast degradation; Grinding due to metal flow at the rail ends; Replacement of broken rail track bolts or rail joint bars.
