Railway Power Solutions


Power solutions for railway and transportation systems have to meet a range of technical specifications and logistic requirements in order to be installed and operated reliably on rolling stock, trackside infrastructure and other mobile platforms. Our engineering and project management teams are experts in this area.


Thousands of XP Power products have been installed on rolling stock and trackside equipment globally. Applications include signalling, crossing control, in-cabin radio and displays. Our products are designed to meet harsh requirements and undergo extensive environmental testing, safety approvals, design verification testing (DVT) and HALT testing. Our engineering teams are located worldwide to be close to our customers, they use only approved component suppliers and components that meet our conservative design guidelines, ensuring reliability is designed in from the ground up.
