Engineered for Reliable Onboard Rail Applications

Syslogic continues to push the boundaries of embedded computing with the Railway Computer RSL 83, an EN50155-certified device powered by Intel’s Amston Lake processor. Designed specifically for railway applications, this rugged and efficient system offers long-term availability, low lifecycle costs, and high reliability in demanding rail environments.

Robust and Efficient Design

At the core of the Railway Computer RSL 83 is the Intel Atom x7211RE processor, built using a 10nm process for enhanced performance efficiency. Engineered for fanless operation, the system boasts low power consumption (under 12W) while ensuring high Mean Time Between Failures (MTBF).

The industrial-grade design features permanently soldered RAM, an IP40-rated enclosure, and passive cooling with heat-dissipating fins, making it an ideal solution for continuous 24/7 operation in both rolling stock and trackside applications. The RSL 83 meets stringent railway certifications, including:

• EN50155 (Class OT4) – Ensures the device can withstand extreme temperature variations, humidity, and voltage fluctuations typical in railway environments.
• EN50125 – Covers environmental conditions such as temperature, altitude, and exposure to dust, moisture, and chemicals, ensuring the computer functions reliably in outdoor and onboard rail conditions.
• EN45545-2 HL3 – A stringent fire protection standard ensuring that materials used in the device meet high flame resistance and low smoke emission requirements for passenger safety.
• EN61373 – Ensures shock and vibration resistance, guaranteeing the computer’s durability in the high-impact and continuously vibrating environment of railway vehicles.
• EN50121 – Covers electromagnetic compatibility (EMC), ensuring that the device does not interfere with other electrical systems within the train or railway infrastructure.

Additionally, the system supports an input voltage range of 16.8-30V, ensuring compatibility with the standard 24V DC onboard power supply of rail vehicles.

• Rugged Reliability: Certified for harsh railway environments, ensuring durability and stability in vibrating and high-temperature conditions.
• Fanless Operation: Reduces maintenance costs and increases long-term reliability.
• Low Lifecycle Costs: Designed for long-term availability with a fixed Bill of Materials (BOM), minimising system updates and re-certifications.
• Flexible Connectivity: Equipped with 2x Gigabit Ethernet, USB 3.2, real-time clock with up to 48-hour backup, hardware watchdog, and TPM 2.0 security module.
• Pre-configured OS Options: Compatible with Linux Debian and Windows 10 IoT Enterprise LTSC, ensuring easy integration into existing railway infrastructures.

The Railway Computer RSL 83 is built for reliable, low-power computing and is well-suited for various railway applications, including:

1. Passenger Information Systems (PIS)

Modern rail travel demands real-time passenger communication, and the RSL 83 plays a crucial role in Passenger Information Systems (PIS). This embedded computer manages train schedules, service announcements, and emergency alerts, ensuring that passengers remain informed throughout their journey. It integrates with digital displays, onboard infotainment systems, and audio announcements, delivering a seamless information flow that improves passenger experience and operational efficiency.

2. Network Applications & Data Logging

Railway operations rely on data-driven insights for predictive maintenance, security, and fleet management. The RSL 83 acts as a network node that securely transmits real-time data from onboard systems to central control units. This data can include engine performance metrics, environmental conditions, and fault detection logs, helping railway operators maintain optimal train performance and safety.

3. Trackside & Wayside Monitoring

The RSL 83 is ideal for trackside monitoring applications, supporting sensors, cameras, and AI-driven diagnostics. Rail infrastructure must be continuously inspected for wear and tear, track misalignment, and overhead line issues. By processing real-time data, the RSL 83 enables predictive maintenance, minimising service disruptions and preventing costly repairs before they escalate into serious failures.

4. Onboard Edge Computing

The increasing demand for autonomous and AI-driven railway operations requires powerful edge computing solutions. The RSL 83 enables real-time data processing directly on the train, reducing dependency on cloud computing and minimising latency.  This is particularly beneficial for collision avoidance systems, video surveillance analytics, and intelligent braking systems, improving overall railway automation and safety.

5. Railway Cybersecurity & Secure Communication

As railways become more digitally connected, cybersecurity becomes a top priority. The RSL 83 includes a Trusted Platform Module (TPM 2.0), which enhances secure boot, encryption, and authentication protocols.  This feature helps protect railway networks from cyber threats, ensuring secure communication between trains, stations, and control centres.

6. Environmental & Energy Efficiency Monitoring

Sustainability is a growing focus for railway operators. The RSL 83 can support energy-efficient train operations by collecting and analysing fuel consumption, regenerative braking efficiency, and environmental impact data. By integrating with green energy solutions, it aids in reducing the carbon footprint of railway operations.
