Railway applications - Urban guided transport management and command/control systems - Part 3: System requirements specifications

This part of IEC 62290 specifies the system architecture for Urban Guided Transport
Management and Command/Control systems (UGTMS) as defined in IEC 62290-1 and
IEC 62290-2, and the allocation of functions and requirements defined in IEC 62290-2 to the
different UGTMS subsystems (designated as system constituents in IEC 62290-1 and
IEC 62290-2), for use in urban guided passenger transport lines and networks.
This document is applicable for new lines or for upgrading existing signalling and command
control systems.
This document is applicable to applications using:
• continuous data transmission
• continuous supervision of train movements by train protection profile
• localisation by reporting trains, and optionally by external wayside equipment for nonreporting
ones (e.g. in case of mixed operation or degraded operation)
This document is not applicable to existing command and control systems or projects in
progress prior to the effective date of this document.
The functional allocations of the UGTMS subsystems are mandatory (forming a sort of core
system) or optional, according to the mandatory/optional functions and requirements defined
in IEC 62290-2.
This document is applicable as a basis to define FIS and FFFIS. For specific applications,
some elements may be added to meet the requirements coming from additional functions or
equipment.

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION

IEC 62290 standard series specifies the functional, system and interface requirements for the

command, control, and management systems intended to be used on urban, guided

passenger transport lines and networks. This series does not apply to lines that are operated

under specific railway regulations, unless otherwise specified by the authority having

jurisdiction.
These systems are designated herein as Urban Guided Transport Management and

Command/Control Systems (UGTMS). UGTMS cover a wide range of operations needs from

non-automated (GOA1) to unattended (GOA4) operation. A line may be equipped with
UGTMS on its full length or only partly equipped.

This series does not specifically address security issues. However, aspects of safety

requirements may apply to ensuring security within the urban guided transit system.

The main objective of this series is to achieve interoperability, interchangeability and

compatibility.

This series is a recommendation for those transport authorities wishing to introduce

interoperable, interchangeable and compatible equipment.

It is the responsibility of the transport authority concerned in accordance with the authority

having jurisdiction to decide on how to apply this series and to take into account their

particular needs.

IEC 62290 series is also intended to support applications for upgrading existing signalling and

command control systems. In this case, interchangeability and compatibility could be ensured

only for the additional UGTMS equipment. Checking the possibility for upgrading existing

equipment and the level of interoperability is the responsibility of the transport authority

concerned.

Application of the series should take into account the differences between the various

networks operated in different nations. Those differences include operational and regulatory

requirements as well as different safety cultures.

This series defines a catalogue of UGTMS requirements split into mandatory and optional

functions. The functions used are based on the given grade of automation. By fulfilling the

requirements, a supplier can create one or more generic applications including all mandatory

functions and all or a subset of optional functions. A generic application will achieve

interoperability within the defined specific application conditions. Customising a generic

application will create a specific application taking into account of local conditions such as

track layout and headway requirements. It is the choice of supplier and transport authority to

add additional functions to a generic or specific application. These additional functions are not

described in this series.

According to IEC 62278, it is the responsibility of the transport authority, in agreement with

the authority having jurisdiction, to decide, taking into account their risk acceptance principles

to conduct specific hazard and risk analysis for each specific application. The safety levels for

the functions of each specific application have to be determined by a specific risk analysis.

Terms like "safety related command", "safety conditions", "safe station departure" are

mentioned without having performed any hazard analysis.

SIST EN IEC 62290-3:2020
IEC 62290-3:2019  IEC 2019 – 7 –
Standard series IEC 62290 is intended to consist of four parts:

• Part 1 “System principles and fundamental concepts” provides an introduction to the

standard and deals with the main concepts, the system definition, the principles and

the basic functions of UGTMS (Urban Guided Transport Management and
Command/Control Systems).

The three other parts correspond to the three steps (see Figure 1) required in the process of

specifying UGTMS and are to be used accordingly.

• Part 2 “Functional requirements specification” specifies the functional requirements

associated to the basic functions provided by Part 1, within the system boundaries and

interfaces as defined in Figure 3 of Part 1.

The FRS (Functional Requirements Specification) identifies and defines the functions

that are necessary to operate an urban guided transport system. Two types of

functions are distinguished for a given grade of automation: mandatory functions (e.g.

train detection) and optional functions (e.g. interfaces to passenger information and

passenger surveillance systems). Requirements of functions have the same allocation,

unless they are marked otherwise.

• Part 3 “System requirements specifications” deals with the architecture of the system

and the allocation of the requirements and functions identified in Part 2 to architecture

constituents.
The SRS (System Requirement Specification) specifies the architecture of a UGTMS
system, with mandatory and optional constituents.

• Part 4 (under consideration) “Interface specifications” deals with the definition of the

interfaces, as well as the data exchanged by them (FIS and FFFIS), for the
interoperable and interchangeable constituents identified in Part 3.

For interfaces between UGTMS constituents, the logical interface or FIS (Functional

Interface Specification) and/or the physical and logical interface or FFFIS (Form Fit

Functional Interface Specification) will be considered.

NOTE The specific structures of Part 3 and Part 4 will be established following completion of Part 2 to

accommodate optional and mandatory constituents, and to reflect local conditions. In principle, only one FIS or/and

FFFIS will be defined for the same interface. However, when justified in some cases, several FISs or several

FFFISs will be defined for the same interface.

Requirements are those necessary to fulfil all operational needs for safe and orderly operation

requested by transport authorities without regard to technical solutions.

The chosen level of detail in describing requirements enables customers as well as authorities

having jurisdiction to be assured that generic applications delivered by different suppliers will

cover at least the same functionality as specified in this part of IEC 62290.

Requirements which are established by this series are indicated clearly with a requirement

identification number related to the function to be covered.

Part 3: System requirements specification
1 Scope

This part of IEC 62290 specifies the system architecture for Urban Guided Transport

Management and Command/Control systems (UGTMS) as defined in IEC 62290-1 and

IEC 62290-2, and the allocation of functions and requirements defined in IEC 62290-2 to the

different UGTMS subsystems (designated as system constituents in IEC 62290-1 and
IEC 62290-2), for use in urban guided passenger transport lines and networks.

This document is applicable for new lines or for upgrading existing signalling and command

control systems.
This document is applicable to applications using:
• continuous data transmission
• continuous supervision of train movements by train protection profile

• localisation by reporting trains, and optionally by external wayside equipment for non-

reporting ones (e.g. in case of mixed operation or degraded operation)

This document is not applicable to existing command and control systems or projects in

progress prior to the effective date of this document.

The functional allocations of the UGTMS subsystems are mandatory (forming a sort of core

system) or optional, according to the mandatory/optional functions and requirements defined

in IEC 62290-2.

This document is applicable as a basis to define FIS and FFFIS. For specific applications,

some elements may be added to meet the requirements coming from additional functions or

equipment.
