IEC 62290-1:2025

Overview

IEC 62290-1:2025 is an international standard developed by the International Electrotechnical Commission (IEC) that defines the system principles and fundamental concepts for Urban Guided Transport Management and Command/Control Systems (UGTMS). Targeted at railway applications, this standard applies specifically to urban guided passenger transport lines and networks, including new installations and the resignalling or upgrading of existing lines.

This third edition supersedes the 2014 version with significant updates to system environment modeling and equipment requirements, catering to evolving urban transit demands. IEC 62290-1:2025 underscores continuous data transmission, real-time supervision of train movements, and precise train localization through onboard and optionally wayside equipment.

Key Topics

• Urban Guided Transport Management and Command/Control Systems (UGTMS): Covers core system definitions, principles, and basic functionalities essential for managing urban guided transport operations.

• Grades of Automation (GOA): The standard supports automation levels from non-automated operations (GOA1) up to fully unattended operations (GOA4), allowing flexibility in control and supervision methods.

• Continuous Supervision and Data Transmission: Emphasizes the use of continuous data communication and train protection profiles for supervising train movements to enhance safety and efficiency.

• Train Localization Technologies: Utilization of onboard UGTMS equipment for train reporting is mandatory, with optional deployment of external wayside devices for improved accuracy.

• System Environment and Boundaries: Provides an updated framework depicting the interactions between various system elements and external equipment, ensuring clear functional scope.

• Interoperability and Compatibility: Lays out principles to facilitate the integration, interchangeability, and adaptability of UGTMS equipment across different urban transit networks.

• Functional Requirements and Performance: Specifies baseline system descriptions and essential functional requirements to guide transport authorities in system acquisition and implementation.

Applications

IEC 62290-1:2025 is especially valuable for:

• Urban Transit Authorities: A foundational guide for specifying and procuring command and control systems that meet international interoperability requirements.

• Signaling and Control System Upgrades: Provides recommendations to upgrade or retrofit existing urban transit signalling infrastructures while ensuring compatibility with new UGTMS components.

• Automation Implementation: Assists in the phased introduction of automation technologies from semi-automated to fully unattended urban transit operations.

• Safety and Operational Management: Enhances safe train operation through continuous supervision and localization technologies, supporting operational performance and passenger safety.

• Intermodal Transport Systems: Facilitates interoperability between neighboring urban transit networks, promoting seamless passenger transfers and network integration.

Related Standards

IEC 62290-1:2025 is part of the broader IEC 62290 series, which collectively specifies the functional, system, and interface requirements for urban guided transport management and command/control systems. Transport authorities and system integrators are advised to consider complementary standards within the series to address specific aspects such as:

• System Implementation and Integration
• Communication Protocols and Data Transmission
• Safety and Reliability Standards (RAMS)
• Electromagnetic Compatibility
• Accessibility and Mobility Requirements

For comprehensive planning and procurement activities, the IEC 62290 series offers a unified framework facilitating the deployment of interoperable, efficient, and scalable urban guided transport systems.
