What Does OEM-Equivalent Really Mean for Traction Motors?
Procurement teams often ask whether aftermarket traction motors truly meet the performance of original EMD® or GE® units. Supco Canada's answer is documented in every test report.
Which EMD® Traction Motor Platforms Do You Supply?
Supco Canada stocks and manufactures components for the full D-series family: D77, D78, D87, D90, and D100. These cover the majority of EMD® GP38, GP40, SD40, SD70, and SD90 locomotive fleets operated worldwide.
- → D77 / D78 — prevalent in Turkish (TCDD) and Egyptian (ENR) fleets
- → D87 / D90 — widely used in North American Class I railroads
- → D100 — modern platform for SD90/SD70 series
How Does Supco Canada Verify Part Quality?
Every outgoing part passes through a documented inspection process under our ISO 9001:2015 certified QMS. Traction motors undergo high-potential (HiPot) testing, insulation resistance verification, and dimensional inspection against OEM drawings.
- → HiPot test: 1,500 V AC per IEC 60034
- → Insulation resistance: ≥ 100 MΩ @ 500 V DC
- → Load test prior to release
What Makes Supco Canada Different from OEM Suppliers?
As an independent aftermarket manufacturer we can offer shorter lead times, competitive pricing, and flexible supply terms — without compromising on technical standards. Our parts are designed for direct interchangeability with OEM.
- → Lead times typically 2–6 weeks vs. 12+ weeks OEM
- → Exchange remanufacture programs available
- → Export to 4 continents with full trade documentation

Yes. Supco Canada holds ISO 9001:2015 certification covering design, manufacture, remanufacture, and supply of aftermarket railway components. Every shipment includes a certificate of conformance and full dimensional/test traceability under our certified Quality Management System.
Do Supco Canada parts directly replace OEM components?
Yes. Our parts are manufactured to OEM-equivalent or OEM-interchangeable specifications. Our Supco Canada part numbers (e.g., SCG-TM-D87) cross-reference to EMD® and GE® OEM numbers, allowing direct substitution without engineering modification.
What countries does Supco Canada export to?
Supco Canada actively supplies railway operators in the United States, Canada, Turkey, Saudi Arabia, and Egypt. We handle full export documentation including certificates of origin, commercial invoices, and packing lists for all international shipments.
What is the lead time for locomotive components?
Lead times vary by product. Stocked items typically ship within 1–2 weeks. Custom-manufactured or remanufactured components generally require 4–8 weeks. Contact our sales team with your part number for a firm lead-time quotation.
Can I order remanufactured parts instead of new?
Yes. Supco Canada operates an exchange remanufacturing program for traction motors and generators. You ship your core unit to our Maple, Ontario facility and receive a fully tested remanufactured unit in exchange — at lower cost than new manufacture with equivalent warranty.
