Reliable UK Castings for Rail Maintenance & Infrastructure
The rail industry faces unique challenges — from sourcing obsolete parts to replacing low-volume, wear-critical components. At Boro Foundry, we’ve supported the sector for decades by supplying precision-engineered castings for everything from maintenance equipment to rolling stock assemblies.
Unlike mass-production foundries, we specialise in small batch rail castings, one-off legacy components, and strict quality control — all from our UK-based, ISO-accredited facility.
Supporting Legacy Part Replacement & Low-Volume Runs
As parts age out of production, maintaining rail infrastructure becomes increasingly difficult. We help overcome this by reverse engineering legacy components and producing bespoke castings in a wide range of materials, including SG iron, austenitic iron, and custom alloys selected for strength, wear resistance, and compliance with public transport safety standards.
Our location and agile production model allow us to offer:
• Fast turnaround
• Low minimum order quantities
• Direct communication with engineers
• Full material traceability
Case Studies
Stone Blower Track Maintenance Casting
Stone blowers are used to restore track geometry, and the stone blower casting itself is a wear part that must be replaced after repeated use. We worked with a customer to redesign this component using an alloy tailored to its operating conditions, extending service life by up to 20%.
In addition, we added identification-friendly design features — not included by the OEM — to make field recognition and replacement more efficient for engineers.
SG Iron Yoke Castings for Rail Couplers
Yoke castings are critical components in bogies and coupling systems. These parts must reliably distribute forces during operation and are subject to stringent mechanical property testing.
We worked closely with a rail OEM to deliver SG iron yoke castings that met all required specifications. Thanks to our deep knowledge of SG iron, UK manufacturing, and full mechanical certification capabilities, we delivered high-integrity parts on a short lead time — reducing inventory overhead and improving supply chain control for the client.
FREQUENTLY ASKED QUESTIONS
Can you supply obsolete or legacy rail components that are no longer in production?
Yes. We regularly reverse engineer obsolete or legacy rail parts — even when drawings are unavailable — to create precise replacement castings that match the original in both function and safety standards.
Do you offer small batch or one-off rail castings?
Absolutely. Unlike mass-production foundries, we specialise in low-volume and one-off castings, ideal for maintenance and replacement parts where high quantities are not practical.
What materials do you use for rail castings?
We cast in a wide range of materials including SG iron, austenitic iron, and custom alloys. Material selection is tailored to ensure strength, wear resistance, and compliance with public transport safety regulations.
How do you ensure your rail castings meet safety and quality standards?
As a UK-based ISO-accredited foundry, we operate under strict quality controls. Every casting undergoes full material traceability, mechanical property testing, and compliance checks to meet rail industry safety standards.
Can you improve the service life of existing rail components?
Yes. We work with clients to redesign and optimise parts for improved performance. For example, we extended the service life of a stone blower casting by up to 20% through alloy selection and design enhancements.
