IEC 62290-2:2025

Overview

IEC 62290-2:2025 is an international standard developed by the International Electrotechnical Commission (IEC) that defines the functional requirements specification for urban guided transport management and command/control systems (UGTMS). This standard applies specifically to urban guided passenger transport lines and networks and serves both new infrastructure and upgrades to existing signalling and control systems.

As part of the IEC 62290 series, this document establishes the baseline system description, operational functions, and interfaces for UGTMS, which supports a range of train automation levels from manual operation (GOA1) to unattended train operation (GOA4). This edition, released in 2025, updates and expands the previous 2014 edition to reflect modern urban rail transport needs and technological advancements.

Key Topics

IEC 62290-2:2025 provides comprehensive coverage of the following core aspects of UGTMS:

• Functional Requirements for Safe Train Operation
  It details the functions to ensure safe route setting, train separation, speed supervision, and authorization of train movements, including degraded operational modes for safety in non-standard conditions.

• Train Operation and Supervision Functions
  The standard specifies train driving controls, station stopping, obstacle prevention, passenger transfer management, and emergency situation handling such as fire, derailment, or broken rails.

• Operation Management and Supervision
  Functions include daily timetable management, train scheduling, regulation of train service, disturbance management, and energy-efficient train dispatching.

• Safety and Emergency Management
  Procedures and control functions for reacting to onboard emergencies, passenger requests, loss of train integrity, and supervision of train doors and traction power.

• Interface and Communication
  Requirements for interacting with operations control Human-Machine Interfaces (HMIs), onboard driver interfaces, passenger information and surveillance systems, and maintenance support.

• Adaptability to Different Grades of Automation (GOA)
  The document provides guidance on mandatory and optional functions depending on the chosen automation level, allowing transport authorities to tailor systems to specific operational needs.

• Informative Annexes
  Included annexes offer user recommendations, typical system performance criteria, and an overview of function applicability based on automation grades.

Applications

IEC 62290-2:2025 is crucial for:

• Transport Authorities and Urban Transit Operators
  To define functional specifications during procurement and to ensure interoperability and interchangeability of urban guided transport command and control systems.

• System Integrators and Equipment Manufacturers
  To design and implement signaling, control, and management systems that meet rigorous international standards for urban guided transport networks.

• Upgrading Existing Urban Rail Infrastructure
  Facilitates modernization of signalling and command/control functionalities while maintaining safety, efficiency, and compliance with international best practices.

• Automation Level Customization
  Helps transit agencies to adopt appropriate technology that ranges from manual operation to fully unattended train control, optimizing cost and operational efficiency.

Related Standards

IEC 62290-2:2025 is part of the broader IEC 62290 series focused on urban guided transport systems. Key related standards include:

• IEC 62290-1 – Baseline system description and overall requirements for command, control, and management systems in urban guided transport.
• Other parts of the IEC 62290 series focusing on interfaces and system integration specifics.

Moreover, while IEC 62290-2:2025 addresses functional and operational requirements, it delegates security considerations to other complementary standards covering cybersecurity and physical security aspects of urban transit systems.

This standard supports harmonized development of urban rail command and control systems worldwide, promoting safe, efficient, and interoperable urban transit solutions aligned with international regulations and evolving technology trends.
