What are the different types of railway tension clips?

Common types of railway tension clips include E-type, SKL, and PR series clips, along with others like Deenik, Nabla, and Fastclip. These clips are elastic fasteners that vary by model number and are designed for different applications, such as high-speed or light rail tracks.

Common types of railway tension clips

• E-type Clips: A common type with specific models like E1609, E1809, and E2009.

• SKL Tension Clips: Includes many models, such as SKL1, SKL3, SKL12, and SKL14.

• PR Series Clips: Another series that includes models like PR clip, PR clip, E2005, and E2007.

• Deenik Clips: Another type of elastic rail clip.

• Nabla Clips: A distinct type of rail clip.

• Fastclip: A type of elastic rail fastener.

• KPO Fastening System: A clamp-based system used in some regions.

• Other Types: Additional variations include Russian clips, Korea clips, Fastclip, N clips, and D-type clips.

Rail track supports vehicle and is fixed to the railway sleeper by rail fastening system. As the core part of rail fastening system, the bending and distortion of rail clip will produce crimping force on the rail track, which ensure the reliable connection between rail tracks and keep the integrity of rail track. Besides, the rigid contact of vehicle and rail track will cause vibration, the elastic structure of rail clip can absorb the impact energy during the train operation, reduce the shocking. The elastic rail clip works under the repeated alternating stress. It bears various effects such as bending, torsion, fatigue and corrosion. When the vehicle passes, it also bears extremely high instantaneous impact load.

With the increase of the axle load of railway vehicles and the improvement of train running speed, as well as the development of urban rail transit and subway, the rail clip, as a key link of the track structure, are also constantly developing, and its importance has attracted more and more attention from various countries. It needs elastic rail clips with different performance to meet the requirements of different track. For example, in the conventional line, it requires elastic rail clip to meet the needs of heavy load and high-speed lines. However, in the seamless track of viaduct, in order to reduce the interaction between the rail and the bridge, the fastener resistance is required to be small, the elastic rail clip is guaranteed to have a low degree of steel, so as to ensure that the buckle pressure loss caused by the compression of the underlayer of the rail when the train passes, and the fastener is not loose.
