For decades, we have been building railway power systems for regional and long-distance railway operations. The development of innovative products and manufacturing technologies, customer-oriented operating practices, and complex project management are significant capabilities that you will find throughout our company: from consulting, to engineering and manufacturing, and erection.

Public regional commuter railways in German and Swiss metropolitan cities and Deutsche Bahn AG have placed their trust in Elpro systems.

Under one roof

We concentrate all required core competencies in our business. The project manager coordinates the required deliverables throughout all implementation phases of a contract, and is at all times available as your competent point of contact.

Our services

  • Fabrication of new rectifier sub-stations
  • Upgrades and complete overhauls of existing systems
  • Erection and commissioning
  • Short-circuit testing
  • Training customer staff
  • Maintenance and service

The main components of our railway power systems are fabricated in-house. This approach not only ensures the quality of the output but also allows us to guarantee that systems are completed on-time, while maintaining complete control of costs.

Switchgear up to 3.6 kV DC

The equipment we manufacture for rectifier sub-stations includes the following products (among others):

All Elpro products are type-tested and meet the respective DIN EN standards. They are intended for use in DC rail power supply systems for a rated voltage of up to 3.6 kV DC.

We build the future

The product components adapted to the special requirements of rail electrical power operations - such as the disconnectors developed by our business -are also available for a rated voltage of 3.6 KV DC. We manufacture

  • Rail disconnectors (EST)
  • Small disconnectors (EKT)
  • Double disconnectors (EDT)
  • Triple disconnectors (ETT)

The high-speed switch module(HSSM) we manufacture was also developed in-house and is among the major inventions from Elpro. The HSSM facilitates fast, wear-free, and bi-directional shut-downs of operating and residual current in forward and reverse direction without contact scorching since an arc is avoided when switching operating and short-circuit currents.

Efficient and effective monitoring and control of equipment and systems for DC railway power applications was implemented by building the combined protection and control unit (SGBA) from Elpro.
