Railroad Solutions
Modern railway networks depend on onboard computing that functions without interruption through vibration, temperature swings, and continuous duty cycles that exceed what standard industrial equipment tolerates. ARBOR designs EN 50155 certified embedded systems for these conditions, supporting passenger information control, IP video recording, and carriage emergency communication from a single deployable platform.
Railway Application Scenarios
Passenger Information & Control Systems (PISC)
The ARBOR In-Vehicle Box PC operates as a PIS (Passenger Information System) control unit within rail carriages. It manages communication between the driver's cab and onboard emergency systems, delivers real-time arrival announcements, and coordinates display and audio output throughout the train.
The architecture supports flexible deployment across different rolling stock configurations, with software interfaces designed to accommodate integration with existing fleet management infrastructure. EN 50155 certification confirms compliance with the electrical, mechanical, and environmental requirements for onboard railway electronics.
Relevant use cases:
- Cab-to-carriage communication relay
- Station arrival information broadcast
- Emergency system status monitoring
- Multi-zone display and speaker control
Onboard Network Video Recording (NVR)
The NVR variant of the In-Vehicle Box PC adds M12 and M8 connectors designed for secure camera connections in high-vibration environments. M12 locking connectors reduce the risk of signal interruption caused by train movement and mechanical stress-a common failure point in standard RJ45-based deployments.
The system records continuously at high resolution while maintaining stable throughput for live monitoring. Video data can be accessed remotely over the onboard network or stored locally with configurable retention policies.
Key features:
- M12 and M8 connector interfaces for camera deployment
- Stable recording under shock and vibration per EN 50155
- Compatible with standard IP surveillance management software
- Supports both local storage and remote retrieval configurations
AI-Assisted Passenger Safety Monitoring
Traditional camera systems capture footage after events occur; edge-based AI inference identifies anomalies as they develop. ARBOR's railway platforms support AI inference workloads at the onboard edge, enabling video analytics, including crowd density detection, unattended object identification, and abnormal behavior recognition, without requiring continuous uplink to a central server. This reduces response time and lowers dependency on trackside connectivity.
The configuration is relevant for metro, regional rail, and intercity operators seeking to add analytical capability to existing CCTV infrastructure while maintaining EN 50155 compliance.
Platform Certifications
ARBOR's In-Vehicle computing platforms for railway are validated against the following standards applicable to rolling stock electronics:
| Standard | Scope |
|---|---|
| EN 50155 | Electronic equipment for railway vehicles - electric, thermal, and mechanical requirements |
Operating temperature range and power supply input specifications are available on individual product datasheets. ARBOR's engineering team can assist with reviewing site-specific installation constraints before procurement.
Integration with Existing Railway Systems
ARBOR's embedded systems are designed to work alongside existing rolling stock electronics:
- Digital signage networks: The In-Vehicle Box PC connects to standard display protocols used in passenger carriage infotainment systems.
- Surveillance management platforms: NVR outputs are compatible with widely deployed video management software (VMS) used in transit security operations.
- Fleet telematics: Ethernet and serial interfaces allow data exchange with onboard diagnostic and telemetry systems.
