About Us

gmp-railtech is the railway technology division of the gmp group, supplying power electronics components for rolling stock — auxiliary converters, DC/DC converters, converter modules, and battery chargers — to customers across the rail industry.

Our Mission

Our mission is to keep engineering and maintenance teams supplied with reliable, standards-compliant power electronics components — and with the technical expertise needed to specify the right one. Rolling stock applications leave little room for error: components must meet EN 50155 requirements for railway electronic equipment and EN 45545-2 fire safety requirements, withstand the temperature and vibration conditions of onboard environments, and remain available over the long service life of a vehicle fleet.

Our Product Range

We supply power electronics for locomotives, metros, light rail vehicles (LRVs), and electric multiple units (EMUs), including:

Who We Serve

gmp-railtech supports OEM development engineers specifying components for new vehicle designs, maintenance and retrofit teams sourcing replacements for legacy converter equipment, system integrators building auxiliary power systems, procurement teams at transit operators, and trading partners across the rail supply chain.

Our Values

Reliability, technical accuracy, and customer focus are the foundations of how we work. In an industry where component compliance and long-term availability are safety-relevant, we aim to build lasting partnerships with our customers and provide the detailed technical support — not just products — that rolling stock projects require.
