Using the finest quality RAILWAY cable, connectors and cable assemblies, Promark Electronics designs engineers and manufactures custom connectivity solutions for the RAILWAY industry.

Railways depend on rugged solutions that perform consistently in harsh environments including extreme hot and cold temperatures, humidity and other factors. Our interconnectivity solutions apply to monitoring power supply, catenary position and wheel-track interaction, controlling wheel and track shape, maintaining telecom networks, door closing systems and onboard entertainment. Promark Electronics solutions meet the highest safety and performance standards.

Promark Electronics – A Partner for the Future!

As a true partner, Promark electronics is here as the resource for cable assemblies, wire harnesses and box build requirements. With engineering expertise, we guide our customers to identify the optimal cable, connectors and electronic components for the specified defence program.

Understanding the objectives of governments through the Defence Policy Review (DPR), Report on Plans and Priorities (RPP), and the Defence Acquisition Guide (DAG) are essential to our process.  

Defence procurement strategies for each country can be different, but Promark Electronics has the ability to understand the requirements and adapt quickly with our years of experience supporting defence programs.
