EN50155 and EN50121-4 Railway Networking Solutions

We supply compliant networking equipment built to meet the demands of rail and trackside deployments. Our range of EN 50155 and EN 50121-4 approved switches, routers, media converters and wireless devices ensures reliable data transmission in harsh rail environments, from onboard rolling stock to outdoor trackside installations.

These devices are tested for vibration, shock, temperature extremes, and EMC compliance, allowing them to support critical applications such as passenger information systems, CCTV, train control, and real-time diagnostics. Many models feature M12 connectors, wide input voltage support, and extended temperature operation for maximum durability.

Where Is Rail Networking Equipment Used?

Rail-approved networking devices are deployed across multiple parts of the UK rail network, including onboard rolling stock, signalling cabinets, trackside enclosures and station platforms. They deliver reliable communication for systems such as passenger information, onboard Wi-Fi, CCTV, diagnostics and control networks. Built for continuous operation, they perform consistently in moving, exposed or vibration-heavy environments.

What Makes These Devices Different From Standard Industrial Models?

Rail-certified equipment undergoes rigorous testing for fire protection, shock, vibration, EMC performance and surge immunity, far beyond standard industrial requirements. Compliance with EN 50155, EN 50121-4 ensures devices operate safely and reliably despite electrical interference, frequent power fluctuations and the demanding conditions found across rolling stock and trackside infrastructure.

EN 50155 vs EN 50121-4 - What's the Difference?

• EN 50155 covers electronic equipment used oboard rolling stock, defining the requirements for temperature, shock, vibration, humidity, power supply variations and long-term durability, ensuring devices can operate reliably inside moving trains.
• EN 50121-4 applies to trackside and signalling environments, focusing on electromagnetic compatibility (EMC) so networking devices do not interfere with signalling equipment and can withstand high levels of interference from passing trains and power systems.

Can Rail Networking Devices Be Integrated With Other Rail Systems?

Yes. Many rail networking products are designed with M12 connectors, rugged housings and wide-range power inputs to align with common rolling-stock and trackside specifications. They integrate seamlessly with onboard control networks, CCTV, passenger information systems and train-to-ground communication platforms, enabling unified data flow across modern rail networks.
