What are the parts of a railway track called?
A railway track consists of main components: Rails (the steel bars), Sleepers/Ties (wood, concrete, or steel supports), Fasteners (clips, spikes, bolts securing rails to sleepers), Ballast (crushed stone for drainage/stability), and the Subgrade/Formation (the earth base). Other parts include Fishplates (joining rails), Switches/Turnouts (for changing tracks), and sometimes Pads (underneath rails for cushioning).
What is the function of rail fastening?
Rail fastening securely connects steel rails to sleepers, maintaining correct track gauge and preventing vertical, horizontal, and rotational movement, while also absorbing vibrations and distributing train loads for safety, stability, and a smoother ride. These systems use components like clips, spikes, and plates to withstand dynamic forces, control rail creep, and ensure proper alignment, which is critical for preventing derailments.

Rail Joints
Rail joints, also named splice bar, fishplates or rail joint bar, is a metal bar that is welded into two rails in order to join them together. It is the most useful product and used in the construction of railway tracks for their sturdiness.
GNEE RAIL can provide various rail joints of high quality according to the requirements of our clients, and our rail joints are up to international standards, such as BS, UIC, GB, AREMA and DIN, etc. in addition, they can be customized in accordance with your specific requirements. Our technical team masters main standards of different countries due to rich experience of the design and production of customized all kinds of Chinese and foreign rail joints, and we can also make necessary adjustments and modifications.

Rail Clip
Rail clip, also called elastic rail clip, it is used to fasten the rail tracks with railroad spike, rail pad, track bolt, rail joint bar together. It is also usually used as a part of rail fastening system. There are huge demand of rail clips on the railway line, about 7000pcs per kilometer, which is directly related to rail safety.
GNEE RAIL as the largest rail clip and clamp production base in China, which has been qualified to tender medium and large scaled railway projects. In addition, GNEE RAIL is approved elastic rail clip manufacturer by China's Railway Ministry and has been ISO9001-2008 certified. Our rail clip product is ideal for rail track assembly for advantages of easy fitment while track laying; economical maintenance; long durability and lifespan; fast replacement.

Rail Pad
A rail pad, also called rail rubber plate, is designed between the rail tie plate and foot of the rail, made by an elastic polyurethane mat, which is interposed between steel rails and tie sleepers to protect the sleeper top from wearing and impacting. Its defined stiffness is used to increase the elasticity of the superstructure of the ballast and reduce shock and vibration in the rail system.
A range of high-performance elastic rail pads have been developed for stiffness requirements and various application areas-from trams through standard gauge railways to heavy haul lines, this especially suitable for E-type rail fastening systems and SKL-type rail fastening system with material of HDPE/EVA/Rubber, the following parameters for reference.
