Product Details

Product Overview

This grooved rail fastener assembly is built for 59R2 and 60R2 grooved rails in tramway networks. It secures the rail to the track foundation, maintains gauge stability, and absorbs dynamic loads from passing trams.

Material composition

The Tram Track Fastening System uses four main components:

A polymer composite baseplate that resists moisture and corrosion

A microporous elastic pad that provides vibration damping

Glass-fiber-reinforced gauge bushings that resist creep and wear

Metal parts manufactured to railway fastener standards

All materials are selected for outdoor exposure, temperature cycling, and long-term load bearing.

Technical specifications

The Tram Track fastener delivers a nominal static stiffness of 40~60 kN/mm per node, or we can customized according to specific requirements. The pad stiffness and overall system stiffness can be adjusted to match different trackbed conditions and project requirements.

Rail lift is set at 20~30 mm. Gauge adjustment covers +8/-16 mm as standard; for special track geometry cases, the range can be extended to +12/-20 mm.

Insulation resistance exceeds 10⁸ Ω, which helps control stray current leakage in tramway power systems.

Installation and field work

Installation of grooved rail fastening system requires standard track maintenance tools. The grooved rail fastening assembly fits directly onto the rail foot and the concrete sleeper or embedded plate. No special training or proprietary equipment is needed.

The modular design means worn parts—such as the elastic pad or bushings—can be replaced individually. You do not need to dismantle the entire fastener or disturb the surrounding track structure.

Compatibility

Tram Track Rail Fastening works with both 59R2 and 60R2 grooved rail profiles. It is suitable for:

New tram line construction

Existing line refurbishment

Rail replacement and gauge correction projects

Service life and reliability

The materials are corrosion-resistant and fatigue-tested. The Embedded Tram Fastening maintains clamping force through millions of load cycles. Field performance data shows consistent gauge retention and minimal pad settlement over years of service.

Ordering and model variation

Different project requirements call for different stiffness values and adjustment ranges. When ordering, please specify:

Required system stiffness (kN/mm)

Required gauge adjustment range

Rail profile (59R2 or 60R2)

Pad material option (standard or high-resilience grade)

We supply each model for Damping Rail Fastener with a dedicated datasheet showing exact dimensions, material grades, and test certificates.

Quality Assurance

Before leaving our factory, the ballast mats will be tested strictly according to standard requirements . For customers who require more, we carry out type tests at our in-house testing centre.

Custom Mould Design & Manufacturing

– In-House, Start to Finish

Our Mould Engineering Department operates a full digital workshop equipped with more than 20 CNC machines, including machining centres, spark eroders, and wire cutters. This allows us to design and manufacture a wide range of moulds for the rail transit industry – injection moulding, rubber, SMC, and specialised types such as auto-core-pulling bush moulds.

Annual output stands at 300 sets of moulds and tooling.

If your project calls for a non-standard shape for Elastic Ballast Mat, a special material, or a unique production feature, we have the equipment and the experience to deliver.
