From 22 to 25 September 2026, DEHN will showcase its 360° protection solutions for railway infrastructure at InnoTrans in Berlin. The manufacturer will present a comprehensive concept covering earthing, lightning and surge protection, plus occupational safety systems for the railway sector in Hall 21, Stand 320. The exhibition targets OEM manufacturers, systems integrators and operators implementing protection concepts for electrically and digitally networked railway systems.
## Signal boxes, FRMCS and point heating in focus
DEHN concentrates on seven application areas in railway technology. Signal boxes, as central control units, receive tailored protection concepts ensuring high availability and standards-compliant operation. For digital communication, the manufacturer showcases solutions for existing GSM-R networks and future FRMCS systems, protecting railway-specific mobile radio infrastructure against lightning and surge effects.
Additional focus areas include level crossing protection – safety-critical interfaces between rail and road – and electric point heating systems, which ensure smooth operation during ice and snow. Properly designed surge protection keeps control systems, sensors and communication infrastructure functioning reliably.
## Earthing and potential equalisation as foundation
Well-conceived earthing concepts and potential equalisation form the basis for effective lightning and surge protection in railway environments. They help prevent dangerous potential differences and reliably safeguard installations. DEHN demonstrates how these requirements can be implemented practically – from planning through to commissioning.
The manufacturer also offers insights into its DEHN Engineering Services via interactive VR experience at InnoTrans. Visitors can see protection solutions demonstrated live and receive advice on standards-compliant protection concepts.
## Occupational safety for railway workers
Railway workers face particular electrical hazards. DEHN presents personal protective equipment and smart devices supporting safe work on and near electrical installations. The portfolio thus covers not only technical infrastructure but also personnel protection.
## Electrification and digitalisation increase requirements
The railway sector is undergoing transformation: energy supply and digitalisation raise demands on availability, safety and standards compliance. According to DEHN, a holistic protection concept is a central component for reliable and future-proof operation. Increasing electrification and networking require resilient systems capable of withstanding lightning and surge effects.
Similarly to photovoltaics and e-mobility, where surge protection for inverters and charging infrastructure is standard, railway technology increasingly requires standards-compliant protection solutions. Manufacturers such as Phoenix Contact and OBO Bettermann also supply surge protection for safety-critical infrastructure.
## Free tickets for trade visitors
DEHN offers trade visitors complimentary exhibition tickets. Interested parties can register online, obtain a ticket code and visit the team on site. The focus is on personal consultation at the stand, where experts will dedicate time to visitors. InnoTrans is an international trade fair for transport technology, attracting decision-makers from across the railway sector.
The exhibition runs from 22 to 25 September 2026 in Berlin. DEHN will present its complete portfolio in Hall 21, Stand 320. Further information and ticket registration available at dehn.de.
