Railway PCB Manufacturing
We manufacture printed circuit boards for signaling and interlocking systems, traction control, and onboard train electronics — equipment that has to keep working through constant vibration, wide temperature swings, and service lives that regularly stretch past 20 years.
Rail programs draw on both our multilayer manufacturing capability and our heavy copper current-handling capacity, often on the same board.

What makes railway PCB manufacturing different?
A signaling board that fails doesn’t just cause downtime — it can compromise the safety systems an entire rail line depends on, which is why this sector holds manufacturing to a different bar than most industrial electronics.
Boards are commonly qualified against EN 50155(Railway PCB Standards: EN 50155 Explained), the standard governing electronic equipment used in rolling stock, and designs go through vibration and shock testing that reflects decades of continuous rail service rather than a typical product warranty period.
Why Railway Programs Choose Us?
- Locomotive and rolling stock electronics manufacturing support compliant with EN 50155 standard
- Combined multilayer and heavy copper capability for signaling and traction applications
- Long-term material sourcing to support 20+ year program lifecycles
- Vibration, shock, and EMC test data available for program qualification

Frequently Asked Questions
Q: Can you manufacture PCBs to EN 50155 requirements for rolling stock?
A: We carry out production in accordance with the materials, processes, and testing requirements for railway projects, and manufacture PCBs and PCB assemblies in accordance with the EN 50155 standard.
Q: What vibration and shock testing do you support for railway boards?
A: We support vibration and shock validation aligned with rail service conditions — see Railway PCB Vibration and EMC Testing Requirements for details on our testing approach.
Q: Do you manufacture both signaling boards and traction control boards?
A: Yes — our signaling and control board resource covers signaling-specific manufacturing, while our heavy copper capability supports the higher-current requirements of traction control systems.
Q: Can you support both bare board fabrication and assembly for railway control systems?
A: Yes. See Section 7 above(Assembly Support for Railway Programs) — we assemble signaling equipment and onboard computer boards in addition to bare board fabrication.
