Rail Clip For Railway Fastening System

Railway Clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. A variety of different types of heavy-duty clips are used to fasten the rails to the underlying baseplate or Sleeper, one common being the E Clip, which is shaped like a stubby paperclip. Another one is the SKL Tension Clamp, which is also the most widely used type all over the world. Others like KPO Clamp and Nabla Clip, also used in different situations.

Description

Technical Parameters

Railway SKL Clips

Feature	Description & Specifications	Notes / Purpose
Product Name	SKL Clip, SKL Tension Clip, Rail Clip, Spring Clip	"SKL" is a common designation derived from its shape and function.
Primary Function	To clamp the railway rail to the baseplate, providing vertical and lateral restraint while allowing for controlled movement and vibration damping.	A key component in elastic fastening systems that maintains gauge and rail alignment.
Application	Used in direct fastening systems for concrete sleepers (ties), bridge decks, and in mass transit systems (metro, light rail).	Common in European and modern railway systems worldwide. Part of the SKL 1, SKL 12, SKL 15 fastening system families.
Governing Standards	EN 13481 (Railway applications - Track - Performance requirements for fastening systems) ISO 10042 National Standards (e.g., German DB standards, Chinese TB standards). Project-Specific Technical Specifications	Performance is tested as part of a complete fastening assembly (clip, baseplate, insulator, sleeper).
Material	Spring Steel • 52CrMoV4 (Chromium-Molybdenum-Vanadium alloy) • 60Si2CrA (Silicon-Chromium alloy)	High-grade alloy steel is required for exceptional fatigue strength, elasticity, and resistance to stress relaxation.

Visual Comparison: E-Clip vs. SKL Clip

It's crucial to distinguish between the two previously discussed clips:

Aspect	E-Clip (Axle Clip)	SKL Clip (Rail Clip)
Function	Axial Fixation (Mechanical)	Clamping Force (Elastic)
Location	Inside the wheelset, on the axle.	On the track, fastening the rail to the sleeper.
Principle	Circumferential Expansion in a groove.	Elastic Deformation to generate a clamping force.
Reusability	Single-use (must be destroyed upon removal).	Potentially reusable if removed carefully and re-tested.
Industry	Rolling Stock (Freight Cars, etc.).	Infrastructure (Track).
