Sourcing Railway Parts
Shouldn't Be This Hard.
Railway operators and MRO workshops worldwide face the same frustrations every day.
Long Lead Times
OEM channels take months. Every day a locomotive sits idle costs thousands in lost revenue and operational delays.
Fragmented Suppliers
Managing 10+ vendors for different part categories drains procurement resources and creates coordination nightmares.
Discontinued Parts
Older EMD, ALCO, and MAN platforms are no longer supported by OEMs -- finding quality replacements becomes a critical bottleneck.
Non-Standard Requirements
Custom drawings, modified specs, or unique fleet configurations mean standard catalogues simply don't cut it.
Quality Uncertainty
Parts that don't meet AAR or UIC standards create safety risks, warranty issues, and costly re-work in the field.
GRS Solves All of This.
One partner. Every part category. AAR & UIC compliant. Custom manufacturing when needed.

Common Questions
Answered Honestly
Can you supply parts for older EMD, ALCO, or MAN locomotives?
Yes. Legacy locomotive platforms are our specialty. We maintain sourcing relationships specifically for discontinued OEM parts, and where parts are no longer available, we can manufacture to your original drawings or samples.
How quickly can I get a quote?
Most enquiries receive a detailed quotation within 24 business hours. Complex custom manufacturing requests may take slightly longer as we evaluate supplier capabilities and lead times.
Do your parts meet AAR and UIC standards?
Yes. We supply parts that meet the applicable AAR and UIC standards for each product category. Compliance documentation is available upon request. For custom parts, we work to your specified standard.
What information should I include in my enquiry?
The more detail, the better. Part number, OEM reference, locomotive or wagon model, quantity required, and your target delivery timeline are most helpful. You can also attach drawings, photos, or datasheets -- up to 100 MB per file.
Do you support long-term or repeat orders?
Absolutely. Long-term supply relationships are our preferred way of working. We can set up scheduled delivery programs, maintain buffer stock, and provide priority service for established partners.
