Frequently Asked Questions About Locomotive Parts Supply
What traction motor models does Supco Canada supply?
Supco Canada supplies aftermarket traction motor components for the EMD® D-series (D77, D78, D87, D90, D100) and GE® 700-series (752 AG/AH, 761) platforms. Our inventory covers the critical structural and electrical components — motor frames, end housings, commutators, brush rigging, coils, and armature hardware — for maintenance shops, national railways such as TCDD, TÜRASAŞ, SAR, ENR, and ERMAS, and industrial operators.
Is Supco Canada ISO 9001:2015 certified?
Yes. Supco Canada holds ISO 9001:2015 certification covering design, manufacture, remanufacture, and supply of aftermarket railway components. Shipments are accompanied by a certificate of conformance and quality documentation under our certified Quality Management System.
Do Supco Canada parts directly replace OEM components?
Supco Canada parts are manufactured with reference to OEM specifications and drawings. Our part numbers (e.g., SCG-TM-D87) cross-reference to EMD® and GE® OEM numbers for identification purposes. Customers should verify suitability for their specific application.
What countries does Supco Canada export to?
Supco Canada actively supplies railway operators in Canada (maintenance shops), the United States (maintenance shops), Turkey (serving TCDD and TÜRASAŞ), Saudi Arabia (serving SAR), and Egypt (serving ENR and ERMAS). 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 components generally require 4–16 weeks depending on complexity and material availability. Contact our sales team with your part number for a firm lead-time quotation.
Can I order remanufactured parts instead of new?
Supco Canada focuses on supplying new aftermarket spare parts rather than remanufactured exchange units. With today's transportation and labour costs, remanufacturing is rarely cost-justified compared to aftermarket new-part pricing. We recommend requesting a quotation for new aftermarket parts — in most cases you will find the price significantly more competitive, with faster availability and no core-return logistics.
