One Source. Every Railway Part.
GRS -- Global Railway Supply -- is a China-based specialist in aftermarket railway parts. We source, supply, and where needed manufacture replacement components for locomotive, wagon, bogie, brake, and track systems -- serving operators, workshops, and distributors across six continents.
A Railway Parts
Specialist, Not a Generalist.
GRS was built around a single focus: railway aftermarket supply. We work exclusively within the rail sector -- locomotive systems, rolling stock, bogie assemblies, braking, and track infrastructure -- which means we speak the language of railway engineers and procurement teams.
Based in China, we combine access to cost-competitive manufacturing with the technical knowledge to specify, source, and quality-check components against AAR and UIC standards. When standard catalogue parts are unavailable, we can work from drawings, samples, or technical descriptions to produce custom parts.
Our customers include railway operators, maintenance and overhaul workshops, rolling stock departments, and parts distributors -- all looking for a reliable, knowledgeable supplier they can return to for the long run.
What Sets Us Apart
Railway-Only Focus
We work exclusively in rail. Every part we supply, every standard we reference, and every conversation we have is within the railway sector -- locomotive, rolling stock, bogie, brake, and track.
We Find It or Make It
If a part is in our network, we source it. If it isn't, we manufacture to your drawings, sample, or specification. Non-standard, obsolete, and custom parts are a core part of what we do.
Built for the Long Run
Railway maintenance is ongoing. We focus on building lasting supply relationships -- consistent quality, reliable lead times, and a team that understands your fleet's requirements over time.
AAR & UIC Standards
We supply components to AAR and UIC specifications -- covering freight and passenger rolling stock for North American, European, African, and CIS railway systems.
One-Stop Sourcing
From locomotive engine internals to track fastening hardware, we cover the full breadth of railway aftermarket parts -- reducing the number of suppliers your team needs to manage.
Global Export Capability
We export to North America, Europe, Africa, Southeast Asia, South America, the Middle East, and the CIS -- with experience navigating the logistics and documentation requirements of each region.
