EN 50155:2026 Railway Electronic Equipment - Rolling Stock Standards

standards.iteh.ai

EN 50155:2026 is a key European standard developed by CLC for the railway sector, specifically addressing electronic equipment installed in rolling stock. This standard sets out requirements for control, regulation, protection, diagnostics, and energy supply components on railway vehicles. EN 50155:2026 defines the environmental, electrical, and operational conditions that electronic systems and components must withstand to ensure safety, reliability, and durability in the demanding conditions of railway service. The applicability of EN 50155:2026 extends to all electronic equipment comprising electronic and associated components like sensors, connectors, printed circuit boards, and semiconductor drive units used within rolling stock subsystems, such as external doors, on-board European Train Control System (ETCS) functionality, and wheel slide protection. By following EN 50155:2026 requirements, stakeholders improve the dependability, maintainability, and lifecycle performance of electronic rail equipment, facilitating safe operation and minimizing downtime and costs.

These include constant vibrations, large temperature changes, strong electromagnetic interference, and power fluctuations. This is exactly where EN50155 certification comes into play, one of the most important standards for electronic components in the railway industry. Constant vibrations, electromagnetic fields from drive systems, extreme weather, and moisture all put electronic systems under stress. The EN50155 standard ensures that electronic devices not only function properly, but are also safe and do not cause operational disruptions. EN50155 certification is based on extensive testing to ensure that electronic devices can permanently withstand the high demands of railway operation. As part of EN50155 testing, components are subjected to defined environmental, climate, EMC, and voltage stress tests. A key element of the EN50155 test procedures is the simulation of real operating conditions over an extended period. For example, devices must tolerate voltage drops, transients, and interruptions of the onboard power supply without losing functionality.

EN50155 is a railway certification that validates the reliability of railway computers to be installed onto rolling stock. Railway computers undergo strict performance tests, such as wide power input and temperature ranges, that prove the reliability to operate in railway applications without maintenance. Railway Compliance Standard EN50155 ensures all electronic equipment installed on rolling stock are reliable throughout its life cycle. Learn how Premio's In-Vehicle Computer is certified to operate in railway applications. As railway vehicles become more advanced and intelligent, there is a demand for ruggedized computers that can: withstand harsh outdoor environments and railway conditions, reliably operate for extensive periods of time with no maintenance, seamlessly connect multiple IoT devices and sensors, and provide the necessary compute power needed to drive all the IoT components. Railway computers and other electronic equipment must be validated and approved by EN50155 in order to be installed onto rolling stock. EN50155 is a strict railway compliance standard for all electronic equipment that is being installed onto rolling stock (or rail vehicle). Equipment is put through numerous performance examinations, performance and insulation tests, that determine the equipment’s reliability of operation, design, and construction.

Shock and Vibrations Given the dynamic nature of transportation of rolling stock, electronic systems must endure vibrations and shocks without compromising functionality. EN 50155 refers to a separate standard (EN 61373) which ensures that the equipment's design is thoroughly examined to verify the presence of suitable fixings and anti-vibration mounts. Today's rail vehicles integrate advanced technologies like real-time diagnostics, AI-powered condition monitoring, predictive maintenance, and passenger information systems, all of which rely on stable, certified electronic platforms. As modern trains transform into intelligent transport hubs and mobile data centers, the need for robust, AI-ready electronic infrastructure is more critical than ever.

The en50155 certification standard refers to the "Electronic equipment used on rolling stock for railway applications" standard. Ethernet equipment used in railway applications typically operates in narrow and harsh environments, which are susceptible to air pollution, vibration, shock, and electromagnetic interference. EN50155/IEC50155 applies to all control, regulating, protection, and power supply electronic equipment installed on railway rolling stock. The shock and vibration tests adopted by EN50155 comply with en 61373 - Railway applications - Rolling stock equipment - Shock and vibration tests. To meet the requirements, electronic equipment should be designed and mounted with specialized anti-vibration brackets. EN50155 specifies that equipment must endure an average annual relative humidity of 75% and continuous relative humidity of 95% for 30 days. An IP67-rated enclosure is undoubtedly a good solution, providing rugged, waterproof, and moisture-proof protection to prevent any failures caused by environmental factors. The EN50155 standard for railway transportation products is one of the commonly used testing standards in the railway industry. Therefore, control electronic equipment installed on railway rolling stock must be certified to the EN50155 standard.
