Dual-port information panels for railway communication are typically modular, with sizes customizable according to installation needs, often built from modules ranging from 20 to 50 points, allowing flexible assembly for full-width or dual-display configurations.

Modular Design and Size

Dual-port panels are generally assembled from separate mounting modules, which can vary in size depending on the manufacturer and the intended application . For example, GEMA s.r.o. produces LED panels with dot spacings from 3 to 30 mm, and the modules themselves typically range from 20 to 50 points, allowing panels to be scaled to the desired width and height for station platforms or onboard displays . This modular approach enables dual-port configurations where two display sections are integrated side by side or stacked vertically.

Display Technology

These panels can use full-color RGB LEDs or LCD backlit with LEDs, providing high contrast and visibility in outdoor or indoor railway environments . LED panels are preferred for outdoor installations due to their brightness and durability, while LCD panels are often used for indoor or sheltered areas. Dual-port panels can display departure, arrival, platform information, and additional passenger messages, with optional features like clocks, automatic announcements, and accessibility functions for visually impaired passengers .

Connectivity and Power

Dual-port panels support serial interfaces, Ethernet, or wireless GSM modules for data transmission . They are typically powered by 230V AC, with optional backup power from solar or public lighting for off-grid installations. Some dual-port panels also include USB ports or headphone jacks for passenger interaction, particularly in onboard railway applications .

Customization and Compliance

Manufacturers like Inelmatic and duagon provide ruggedized dual-port panels designed to withstand vibration, shock, and extreme temperatures, complying with EN50155 and EN45545 standards for railway safety . The modular design allows panels to be tailored to specific platform widths, train interiors, or station layouts, ensuring optimal visibility and integration with existing railway communication systems.

Summary

• Module size: Typically 20–50 points per module, scalable for dual-port assembly
• Display type: LED (single or full-color) or LCD with LED backlight
• Connectivity: Serial, Ethernet, or GSM wireless
• Power: 230V AC, optional backup from solar or public lighting
• Compliance: EN50155, EN45545, ISO9001:2015 for quality and safety
• Customization: Panels can be configured side by side or stacked for dual-port setups, with optional clocks, accessibility features, and passenger interaction ports These specifications ensure that dual-port information panels are flexible, durable, and compliant with railway operational standards, suitable for both station platforms and onboard train installations.
