Nexcom Railway Computers

Nexcom’s Railway Computer systems are engineered for the extreme demands of rail transit. Modern trains and metros require robust, high-performance embedded PCs to handle real-time control, passenger information, surveillance, and communication systems. Mentioned solutions could be technically divided in 3 distinguished groups Atom Compact, Atom Performance and Core Performance. Nexcom’s railway PCs feature fanless, anti-shock designs with dust-proof metal housings, wide-range power inputs and industrial-grade components. They comply with stringent transport standards (EN 50155 for temperature/humidity, EN 50121 for EMC, and EN 45545-2 for fire safety) and are tested to MIL-STD-810 for vibration and shock. In practice, these computers support tasks like digital signage and passenger information displays or “host-to-machine” (H2M) gateways for vehicle monitoring and control. Many models are IP-rated (up to IP67) for outdoor and maintenance use, and systems can run from –40 °C to +70 °C. (Nexcom is ISO‑9001/14001/45001 certified, ensuring quality manufacturing.)

Nexcom Railway PCs connect trains to onboard and central systems with rich I/O (Wi-Fi/5G, CAN, GPS, multiple LAN, serial, PoE ports, etc.). Their use cases include passenger infotainment, communication hubs, video surveillance, and predictive maintenance. For example, Nexcom’s nROK-1030-A railway PC is a versatile, fanless Atom-based system for signage and monitoring. Nexcom emphasizes long lifecycle support and compliance (E1/E13 marking, industry certifications), so operators get reliable, maintained hardware for years. Overall, these computers are built rugged and reliable so trains keep running safely and informatively in all conditions.

Nexcom Railway PC Atom® Compact

The Atom® Compact series offers entry-level railway PCs based on Intel Atom processors. These fanless embedded computers deliver sufficient performance for tasks like basic passenger information systems, lightweight IoT gateways, or simple control consoles. They inherit Nexcom’s rugged features: anti-shock chassis, wide-temperature operation, and multiple expansion options. For instance, Nexcom’s documentation notes that these systems provide “stable and green power supply, industrial-grade reliability and extended product life cycle”. Typical applications include digital signage, data acquisition, and HMI (human-machine interface) terminals in rail cars and vehicles. The Atom Compact PCs usually include multiple LAN, serial/CAN ports, SIM slots and storage bays – enough connectivity for entry-level rolling-stock functions.

Nexcom Railway PC Atom® Performance

The Atom® Performance series steps up to more powerful Atom CPUs (Intel 7th/8th Gen Atom “Apollo Lake/Celeron” etc.) for heavier-duty tasks. These railway PCs often add features like PoE ports and extra storage. They retain ruggedness (wide temperature, EN50155 compliance, shock/vibe-tested) while providing enhanced compute and I/O for tasks such as multiple camera feeds or infotainment. For example, some models integrate 4-channel PoE for surveillance or passenger Wi-Fi. Nexcom highlights “anti-shock design, metal dust-proof ability, stable and green power supply” for all train PCs. In this class, units like the nROK-6231 and 6232 are built around the Intel Atom x7433RE (Gemini Lake) for significantly higher throughput. They support up to eight SIM cards and built-in CAN FD, making them communication hubs between train sensors and central systems.

Nexcom Railway PC Core™ Performance

The Core™ Performance line uses Intel Core or Xeon CPUs (8th–13th Gen) for the most demanding on-board applications. These fanless PCs handle AI inferencing, real-time video processing, and complex control tasks on high-speed trains. Nexcom notes that new rail systems “operate under high efficiency digitalized control” and thus require “embedded computers with the highest levels of performance, longevity and reliability”. Core™ Performance models feature the same rugged chassis and certifications (EN50155, EN45545-2, etc.) but add massive compute, DDR4/DDR5 support, and advanced I/O. For example, the nROK-7270 series supports 12th/13th Gen Core CPUs and up to 64 GB DDR5 ECC, with modular M12 ports for PoE and LAN. These PCs serve as central controllers, AI gateways or multi-screen infotainment servers on trains, where uptime and speed are critical.
