Frequently Asked Questions

Learn More About EN 50155 & EN 50121-4 Railway Networking Devices

EN 50155 is the railway standard associated with electronic equipment used on rolling stock, while EN 50121-4 is the railway EMC standard for signalling and telecommunications apparatus installed in the railway environment. In practice, EN 50155 is most closely tied to onboard rail equipment, whereas EN 50121-4 focuses on emission and immunity requirements for signalling and telecoms equipment around railway infrastructure.

These devices are most useful in applications such as onboard train networks, passenger information systems, CCTV, communications links, TCMS-related networking, and trackside signalling or telecoms infrastructure. Railway networking hardware in this category is chosen where communications equipment needs to remain reliable across real-world rail operating conditions rather than standard commercial environments.

Railway networking devices often use M12 and other circular connectors because rail applications can involve vibration, shock, and demanding installation conditions where secure physical connections matter. Railway switch ranges built for rolling stock and wayside use commonly use these connector types to support tighter, more robust cabling connections in service.

The most important factors are usually where the device will be installed, what kind of network role it needs to perform, the connector and interface requirements, EMC expectations, and whether the project is focused on rolling stock, signalling, telecoms, or wider rail infrastructure. The right product is the one that matches both the communications task and the specific railway environment it has to work in.
