Active USA Freight Railroad OEM — 3 Years, 17 POs, Zero Rejections

In 2024, Amsol began supplying an active USA freight railroad product company — a leading manufacturer of engineered components for North America's freight car fleet. Their components must comply with AAR specifications, meet exacting dimensional tolerances, and survive millions of operational cycles.

Key Outcome
An ISO-Audited USA Railroad OEM That Audited Amsol — and Kept Ordering.

The Situation

An ISO-Audited USA Railroad OEM That Audited Amsol — and Kept Ordering.

In 2024, Amsol began supplying an active USA freight railroad product company — a leading manufacturer of engineered components for North America's freight car fleet. Their components must comply with AAR specifications, meet exacting dimensional tolerances, and survive millions of operational cycles.

When they evaluated Indian suppliers, they conducted a formal ISO 9001:2015 facility audit of Amsol. Amsol passed. The first purchase orders followed within weeks. Three years later, 17 purchase orders across three product lines — zero quality rejections, zero late deliveries, and a fourth product line now qualifying.

The Problem
What the OEM was facing before Amsol.
Required ISO 9001:2015 audited supply partner — not just a foundry with a certificate on the wall
AAR specifications non-negotiable — safety-critical freight rail components
Multiple product types required: forged pins, ductile iron castings, multi-part riveted assemblies
Zero tolerance for quality issues — every rejection is a production line impact
Export documentation and customs compliance required on every shipment to USA
Amsol's Approach
Engineering diagnosis and recommended solution.
ISO 9001:2015 facility audit completed — passed, no findings
Forged alloy steel pins: AISI C1060, Q&T, Brinell verified per batch
Ductile iron castings: DI 65-45-12, parting lines ground flush, manufactured from 3D model
Riveted assemblies: 3-part, countersunk rivets pressed and ground flush per drawing
Full export documentation: MTC, CMM report, packing list, certificate of origin on every shipment
Three Product Lines — Active Supply

What Amsol Supplies — Three Components, Three Processes, One Partner

The relationship grew from one component to three product lines over three years. Each addition required a new qualification — and each passed first time.
