💡 Key Takeaways: IEC 62580 (OMTS)

  • Definition: The global standard defining the architecture for OMTS (On-board Multimedia and Telematic Subsystems).
  • Core Pillars:
    • IEC 62580-1: General Architecture (The Backbone).
    • IEC 62580-2: Video Surveillance / CCTV (Security).
    • IEC 62580-3: Passenger Information Systems – PIS (Communication).
  • Technology: Shifts focus from analog cabling to full IP-based networks (Ethernet) inside the train.
  • Interoperability: Ensures that a PIS screen from Vendor A works with a central computer from Vendor B.
🚀 2026 Outlook: As we move into 2026, IEC 62580 is becoming the foundation for “Smart Trains.” The standard is now being integrated with 5G Real-Time Data offloading and AI-powered Video Analytics (e.g., detecting abandoned luggage via Part-2 protocols).

In modern rail transport, passengers expect more than just a seat. They expect connectivity, information, and security. IEC 62580 is the technical framework that governs the “Digital Experience” inside the rolling stock.

It unifies disparate systems—screens, cameras, loudspeakers, and WiFi—under a single umbrella known as OMTS (On-board Multimedia and Telematic Subsystems).

The Structure of IEC 62580

Unlike mechanical standards, IEC 62580 is modular. It addresses specific subsystems that share the same network infrastructure.

Part 1: General Architecture (The Brain)

This section defines how data flows through the train. It mandates an IP-based Network (often Gigabit Ethernet) ensuring that high-bandwidth video data doesn’t crash critical train control commands.

Part 2: Video Surveillance / CCTV (The Eyes)

Security is paramount. IEC 62580-2 defines requirements for on-board CCTV:

  • Frame Rate & Quality: Minimum resolution standards for legal evidence.
  • Storage: Protocols for the “Black Box” video recorder (NVR).
  • Live Streaming: Capabilities for the control center to view inside the train during an emergency via 4G/5G.

Part 3: Passenger Information System / PIS (The Voice)

Gone are the days of static scrolling text. IEC 62580-3 covers dynamic PIS:

  • Real-time synchronization with the train’s GPS location.
  • Interfacing with the TCMS (Train Control and Management System) to display speed or delays.
  • Prioritizing audio streams (e.g., The driver’s emergency announcement must mute the entertainment music instantly).

Legacy vs. Modern OMTS Architecture

Why is IEC 62580 a game-changer for operators? It eliminates “Siloed” systems.

FeatureLegacy Systems (Pre-Standard)IEC 62580 Compliant (2026 Standard)
CablingSeparate cables for CCTV (Coax) and PIS (Serial). Heavy & complex.Single Ethernet Backbone (Shared infrastructure). Light & efficient.
UpdatesManual USB updates on each screen.Over-the-Air (OTA) updates via the central server.
IntegrationProprietary (Vendor Lock-in).Interoperable (Plug & Play components).

FAQ: OMTS and IEC 62580

Does IEC 62580 cover Passenger WiFi?

Indirectly, yes. While the WiFi service itself is a connection method, the Access Points (APs) and the router gateways are part of the OMTS network architecture defined in Part 1, sharing bandwidth with other non-critical systems.

How does IEC 62580 relate to Cyber Security?

Since IEC 62580 promotes IP-based connectivity, it opens the train to potential cyber threats. Therefore, it must be implemented alongside IEC 62443 or TS 50701 (Railway Cyber Security) to ensure hackers cannot access the PIS or CCTV feeds.

What is the difference between PIS and PAS?

PIS (Passenger Information System) is visual and auditory information (Next Stop: Berlin). PAS (Public Address System) is strictly the audio announcement system. Under IEC 62580, PIS usually controls PAS to ensure automated announcements are synchronized with the screens.
