Road-rail (hi-rail) vehicles move between highway and track, cutting mobilisation time for construction, welding and inspection crews.
Typical uses include traction for rail trains in depots, excavators for ballast work, and multi-function machines for tunnel and metro duty.
Tell us your gauge, axle load and whether you need road or rail priority — we will propose a matched package.
Every RAILINK order — from our own line or a partner plant — follows the same four-step discipline:
Ask for a sample inspection report when you inquire — we share redacted examples under NDA.
Choosing a rail fastening system is rarely a brand preference — it is a match between axle load, design speed, sleeper type, track form and your maintenance philosophy.
E-clip systems remain the workhorse for ordinary and heavy-haul ballasted track on concrete sleepers. They are widely available, easy to install and well understood by track crews worldwide.
SKL (Skl) systems (SKL3 / SKL12 / SKL14) are typically specified for higher-speed corridors where gauge retention and fatigue life under continuous welded rail matter most.
W-series systems (W14 / W30) are common on European-style high-speed and heavy applications under EN 13481 performance classes.
| System | Typical use | Key buyer check |
|---|---|---|
| E-clip | Ordinary / heavy haul | Toe load, clip fatigue, pad stiffness |
| SKL | High-speed / metro upgrades | Gauge adjustment, insulator type |
| W-series | EN-spec corridors | Axle load class, sleeper geometry |
Send RAILINK your rail section, sleeper drawing and operating speed — we map the complete fastening kit and quote within 24 hours.
Fishplates (joint bars) for heavy-haul lines must survive high axle loads, impact at joints and, often, low-temperature service.
RAILINK supplies fishplates from its own fastening base and audited partners, with dimensional inspection and packing suited to export.
A rail grinding (or milling & grinding) train restores the rail head profile, removes corrugation and controls rolling contact fatigue before defects become broken rails.
Buyers typically justify grinding when: corrugation noise rises in metro corridors; RCF / head checks appear on mainlines; or life-cycle cost models show grinding cheaper than early rail replacement.
RAILINK sources grinding cars and related equipment through vetted Chinese machinery partners — with one contract and one QC standard.
Procurement teams often mix drawings from different standards. The fastening kit must still be a coherent system.
RAILINK produces and sources to the standard written in your PO. We never claim certificates a factory does not hold.
