IEC 62290-2:2014

Overview

IEC 62290-2:2014 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies the functional requirements for Urban Guided Transport Management and Command/Control Systems (UGTMS). This standard targets urban guided passenger transport lines and networks, offering specifications applicable for both new systems and upgrading existing signalling and command/control infrastructures. It focuses on systems that utilize continuous data transmission, train protection profiles with continuous supervision, and train localisation through wayside equipment or train reporting.

This standard plays a crucial role in ensuring the safety, reliability, and efficiency of urban guided transport networks, providing detailed functional criteria necessary for urban transit operators, system designers, and integrators.

Key Topics

• Safe Train Movement Assurance
  IEC 62290-2 defines functional requirements to ensure safe routing, separation of trains, speed determination, and train movement authorization. It includes continuous supervision aligned with train protection profiles, which enhances operational safety.

• Train Operation and Control
  The standard outlines functions related to driving trains, such as enforcing speed profiles, automatic stopping at stations, and controlling train movements according to operational parameters.

• Guideway and Passenger Supervision
  Important safety features include collision prevention with obstacles and persons on tracks, work zone protection, and control of doors to prevent injuries during passenger transfer.

• Emergency Detection and Handling
  Functional requirements cover detection and reaction protocols for emergencies such as fire, derailment, broken rails, passenger requests, and loss of train integrity, enhancing operational robustness.

• Operational Management Functions
  IEC 62290-2 establishes functions for managing daily timetables, regulating train services, handling operational disturbances, and supervising train tracking and equipment status.

• Interfaces and Communication
  The standard specifies requirements for interfaces with human-machine interfaces (HMIs), communication systems for passengers and staff, passenger information systems, and passenger surveillance systems.

• Maintenance and Resource Management
  Provisions are made for supporting system maintenance and managing rolling stock and staff resources, including assignment and reassignment functions.

Applications

The practical applications of IEC 62290-2:2014 are extensive in the urban transit sector:

• New Urban Transport Systems
  Design and implementation of command and control systems for new guided urban transport lines, ensuring compliance with international safety and operational standards.

• Upgrading Existing Systems
  Enhancing existing signalling and command/control systems with state-of-the-art functionalities to improve safety, efficiency, and passenger experience.

• Safety-Critical Urban Signalling
  Application in continuous or semi-continuous monitoring environments where ensuring train separation, route integrity, and speed adherence is vital.

• Integrated Operations Control
  Deployment within control centers for real-time operation management, emergency handling, and passenger information dissemination.

Urban transit operators, signalling engineers, system integrators, and manufacturers can leverage the standard to develop or improve reliable and interoperable transport management systems in compliance with IEC requirements.

Related Standards

IEC 62290-2 is part of the IEC 62290 series which addresses urban guided transport systems:

• IEC 62290-1 – Covers terms, definitions, and system description, establishing foundational concepts and nomenclature referenced in Part 2.

• Other IEC railway signalling standards that may complement IEC 62290-2 include specifications on communication protocols, safety integrity levels, and rolling stock control.

Alignment with ISO standards concerning urban transit operations and safety may also be considered, fostering interoperability and harmonization across international urban guided transport networks.
