Industry Insight. Technology Know-how.

Robust Solutions for Rolling Stock and Wayside

Modern rail systems depend on robust, high-performance computing and networking infrastructure to connect onboard systems, trackside equipment, and operational control environments. From Train Communication Networks (TCNs) within rolling stock to signalling and telecommunications equipment along the wayside, reliable data exchange is fundamental to safety, efficieny, passenger experience, and regulatroy complaince.

Designed for harsh railway environments, our rail-approved computing and networking solutions are engineered to withstand extreme temperatures, shock, vibration, humididy, voltage fluctuations, and electromagnetic interference. With extensive sector experience, we combine deep technical expertise with leading technology partnerships to provide integrators and Train Operating Companies (TOCs) with reliable, repeatable, and robust solutions for both onboard and trackside deployment.

 

IEC 62443-4-2 in Practice


At Impulse, we help UK organisations specify, integrate, and support IEC 62443-aligned networks and computing platforms, from architecture and product selection through build, configuration, and lifecycle management.

From Specification to Long-Term Support: How We Deliver Railway Computing & Networking Projects

Railway projects need more than product supply alone. We work with customers to define the application, select the right computing and networking platforms, configure and validate systems in the UK, and support change over the full operational life of the deployment.

Application Review & Requirements Capture

Every railway project starts with a clear understanding of the operating environment and system architecture. We review where the equipment will be deployed, how it will be powered, what data and network functions it must support, and which compliance requirements apply. This helps ensure the solution is robust, supportable, and aligned with the realities of rail operation.

Platform Selection & Solution Definition

Once the application is defined, we help select the right railway-certified platforms for both compute and network infrastructure. This may include onboard computers, vehicle routers, managed switches, or associated peripherals. The goal is to build a solution that fits the technical requirement, installation constraints, and long-term support plan.

System Build, Configuration & Validation

Systems are configured and validated in the UK to an agreed project standard. This can include hardware assembly, operating system installation, firmware control, imaging, and test procedures designed around the intended railway application. The aim is to deliver platforms that are prepared for straightforward installation and dependable field operation.

Lifecycle Planning & Ongoing Change Control

Railway deployments are expected to remain in service for many years, so lifecycle planning is a core part of the project. We help maintain configuration control, track manufacturer notices, and manage transitions when products change or reach end of life. This supports long-term continuity and reduces risk across operational rail systems.

Frequently Asked Questions

Railway Computing and Networking FAQs

In most cases, no. Standard industrial computing and networking devices are not built to handle the power fluctuations, shock, vibration, and extreme environmental conditions typical of railway environments. However, in some situations, OEMs developing railway products or systems may choose to use a non-certified device if the entire solution will undergo certification, or if certification is not required for that specific application. In these cases, we can still provide guidance and support to help customers select suitable solutions for their railway projects, even if EN 50155 or other standards are not immediately applicable.
Railway-grade devices are equipped with extended operating temperatures, shock and vibration resistance, power supply resilience, and ingress protection (IP Rating), often IP65 or higher for dust and moisture resistance. In addition, railway devices are built with long product lifecycles, extended support and stable component availability to reduce the need for redesign or requalification.
Railway power supplies are prone to voltage fluctuations, surges, and interruptions. EN 50155-compliant computers handle this with wide-range DC inputs, power hold-up functions, and transient voltage protection to ensure continuous operation even during power disruptions.
Railway environments expose electronics to extreme conditions, including wide temperature fluctuations, vibration and shocks, humidity, and unstable power supplies. EN 50155 ensures that computing systems can withstand these challenges while maintaining reliable performance.
EN 50121-4 certified devices do not emit or suffer from electromagnetic interference (EMI) in railway environments. This is particularly crucial for signalling, communication, and control centre operations where interference could cause system failures or safety risks.
