Product Introduction

The Type V rail fastening system is a high-speed railway system designed for use with 60kg/m rails on ballast tracks and concrete ties with shoulders. It's a type of elastic clip fastening system, composed of various components like screw spikes, flat washers, spring clips, and gauge baffles. This system is engineered to meet the operational demands of passenger-dedicated lines with speeds up to 350km/h and axle loads up to 170kN, as well as mixed passenger and freight lines with speeds up to 250km/h and axle loads up to 230kN.

Product structure and performance characteristics

Structural and Performance Features of V-type Railway Fasteners:

Stable Structure: Shouldered bolt design secures elastic clips via spiral spikes and sleeves, with concrete sleeper shoulders restricting lateral rail movement. Mechanical connections enable easy disassembly and maintenance.
Adaptive Elastic Clips: High-strength spring steel clips (W2 for general sections, X3 for low-resistance bridge sections) use three-point contact for uniform clamping force, meeting diverse track needs.
Flexible Gauge Adjustment: Engineering plastic gauge retainers (7 specs, 2mm step) allow ±8mm adjustment for precise track fit.
Reliable Mechanics:General sections: Clamping force ≥11kN, longitudinal resistance ≥9kN;Bridge low-resistance sections: Clamping force ≥6kN, longitudinal resistance ~4±1kN, balancing rail stability and bridge displacement.
Superior Maintenance & Insulation: Under-rail pads enable 5-10mm height adjustment. Insulated components ensure track circuit operation; galvanized metals and nylon-lined sleeves offer corrosion resistance for efficient maintenance.

Introduction of V-type fastener system components

The elastic clip Type V fastener is composed of spiral spikes, flat washers, elastic clips, gauge retainers, under-rail pads, and embedded sleeves. In addition, to meet the need for adjusting the vertical position of the rail, it also includes height-adjusting pads.

Spring clip

There are two types of elastic clips: the W2-type elastic clip used in general sections and the X3-type elastic clip used in low-resistance sections. The W2-type elastic clip has a diameter of 14mm, while the X3-type elastic clip has a diameter of 13mm. In addition, Type A elastic clips complying with TB/T 1495.2 may be used at rail joints.

Low-resistance Sections	X3-type Elastic Clip	Composite Pad CRP5	4.0±1.0 kN

Elastic Clip Configurations for General Sections and Rail Joints


Line Status	Elastic Clips	Remarks
General Sections	W2-type and X3-type elastic clips	-
Rail Joints	W2-type, X3-type elastic clips and Type A elastic clips complying with TB/T 1495.2	When it is difficult to install W2-type and X3-type elastic clips on small-number gauge retainers at rail joints, install Type A elastic clips.

Under-rail Pads

Under-rail pads are divided into two types: the rubber pad RP5 used in general sections and the composite pad CRP5 (vulcanized from rubber and stainless steel plates) possibly used on bridges.

When it is necessary to reduce the track resistance on bridges, X3-type elastic clips can be used in conjunction with composite pads. In this case, the longitudinal resistance of the rail per set of fasteners is approximately 4.0±1.0 kN.

Gauge Retainers

The gauge retainer G5 is available in seven models: No.2, No.3, No.4, No.5, No.6, No.7, and No.8. For standard gauge, No.4 and No.6 are used.

Embedded Sleeve

This component is pre-embedded in the sleeper, and the embedding accuracy shall meet the requirements. The top surface of the embedded sleeve D1 should be flush with the rail-bearing surface of the sleeper. After embedding, the embedded sleeve shall be covered with a plastic (or other material) cap to prevent rainwater and mud from entering.

Height-Adjusting Pads

The height-adjusting pad TD5 is available in four specifications according to the thickness d: 1 mm, 2 mm, 5 mm, and 8 mm, which are placed between the under-rail pad and the rail-bearing surface of the sleeper.
