A rail clip, also known as a rail clamp, is a metal component that attaches the rail to the sleeper or the tie. It ensures that the rail maintains its correct position and gauge, preventing it from slipping or moving, even when subjected to the heavy loads and vibrations of passing trains.
There are several types of rail clips available in the market, and they differ in terms of their design, materials, and applications. Each type of rail clip has unique characteristics that make it suitable for specific rail types, rail sections, and traffic loads. Elastic rail clip is one of the common railway fasteners in the railway system. In general, elastic rail clip is made of forged spring steel and has many applications. No matter as a part of rail fastening system or as a rail fastener, elastic rail clip is used with other railway track parts, such as railroad spike, rail pad, tie plate and plastic dowel.

Rail Clip Production Process
Adhering to quality first, Gnee Rail pay great attention to rail clip production process. With professional technic workers and strict quality monitoring, Gnee Rail elastic rail clip processing procedures are as follows:
Raw material: High quality spring steel from reliable and certified manufacturers for a long time.
Shearing: Spring steel bar must be cut according to the required length.
Heating: Forging temperature (950-1000 degrees Celsius), but over heating shall be avoided to check decarburization.
Forming: Proper heating rods shall be transferred to the forging press.
Hardening: Forged rail clips moved to the quench tank. Dimensional accuracy and quench hardness of rail clips are checked before tempering.
Tempering: The rail clips are tempered at about 350 Celsius to achieve appropriate toughness in the spring.
Inspection: Products are checked thoroughly as per China CRCC and customer required specification and design.
Packing: Clips can be packed in woven bags or upon customer requirement
Railway clips make it easy to install new rail or thermally adjust the rail to a neutral temperature, ensuring that the track does not buckle. The invention of the elastic fastener has revolutionized rail fastening systems with respect to continuous welded rail. Without these types of fasteners there would be more derailments and potential loss of life with each one.
