Full title and description

Railway applications — Urban guided transport management and command/control systems — Part 1: System principles and fundamental concepts. This international standard (IEC 62290-1:2025, Edition 3.0) provides the baseline system description, core principles and basic functions for Urban Guided Transport Management and Command/Control Systems (UGTMS) used on urban guided passenger transport lines and networks; it is applicable to new lines and to resignalling/upgrading existing systems.

Abstract

IEC 62290-1:2025 introduces the IEC 62290 series and defines key concepts, system boundaries and fundamental functions for UGTMS. The document applies where systems use continuous data transmission, continuous supervision of train movements by a train protection profile, and train localisation reported by onboard equipment (optionally supplemented by wayside devices). It is intended as a baseline for transport authorities preparing requests for proposal and for suppliers aiming at interoperable or interchangeable solutions.

Scope

Defines system principles and fundamental concepts for UGTMS covering a range of operation modes (GOA1–GOA4). Applicable to systems that use continuous data transmission, continuous train-movement supervision via a train protection profile, and train localisation reported by onboard UGTMS equipment (and optionally wayside devices). The part sets out system environment, terms and definitions, grades of automation, general requirements (including RAMS and EMC considerations) and the basic functions expected from UGTMS.

Key topics and requirements

• System concepts, terminology and definitions for UGTMS.
• System environment and boundaries (interfaces to wayside equipment, operations and staff functions).
• Grades of automation (GOA) — descriptions and applicability within UGTMS.
• Requirements for continuous data transmission and continuous supervision via a train protection profile.
• Train localisation and reporting expectations (onboard reporting trains, optional wayside augmentation).
• Baseline functional requirements to support procurement (request-for-proposal) and interoperability/interchangeability objectives.
• References to RAMS (reliability, availability, maintainability, safety) and EMC requirements; alignment with railway RAMS and safety standards.
• Interface and subsystem allocation principles (expanded in Parts 2 and 3 of the series).

Typical use and users

Used by transport authorities preparing procurements and technical specifications, signalling and systems engineers, system integrators, rolling-stock suppliers, operators, RAMS and safety engineers, and certification/approval bodies. The standard is used as a baseline for system design, tender documents, functional allocation and to promote interoperability between suppliers.

Related standards

IEC 62290-2:2025 (Part 2 — Functional requirements specification) and IEC 62290-3:2025 (Part 3 — System requirements specification) form the immediate companion parts of the IEC 62290 series. Related railway normative references include IEC 62278 (RAMS series), IEC 62280 (safety-related communication in transmission systems) and IEC 62425 (safety-related electronic systems for signalling). These documents together address functional, system, interface and safety/RAMS concerns for signalling and UGTMS projects.

FAQ

Q: What is this standard?

A: IEC 62290-1:2025 is the first part of the IEC 62290 series that defines system principles and fundamental concepts for Urban Guided Transport Management and Command/Control Systems (UGTMS).

Q: What does it cover?

A: It covers high-level system definitions, terminology, system environment and boundaries, grades of automation, baseline functions, and general requirements (including RAMS and EMC considerations) for UGTMS applicable to new lines or resignalling projects.

Q: Who typically uses it?

A: Transport authorities, signalling engineers, system integrators, RAMS and safety engineers, rolling-stock suppliers and procurement teams use this standard to specify and evaluate UGTMS solutions and to prepare interoperable procurement documents.

Q: Is it current or superseded?

A: Current — Edition 3.0 (2025) is published and cancels/replaces the 2014 edition (IEC 62290-1:2014). The 2014 edition was withdrawn on publication of the 2025 edition.

Q: Is it part of a series?

A: Yes — it is Part 1 of the IEC 62290 series. Parts 2 and 3 (functional and system requirements) were updated in 2025 and together provide the functional, system and interface requirements for UGTMS.

Q: What are the key keywords?

A: Urban guided transport, UGTMS, signalling, command/control systems, continuous transmission, train localisation, grade of automation (GOA), interoperability, RAMS.
