Part 3: System requirements specification

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.
International Standard IEC 62290-3 has been prepared by IEC technical committee 9:
Electrical equipment and systems for railways.
This second edition cancels and replaces the first edition issued in 2019. It constitutes a
technical revision.
The main technical changes with regard to the previous edition are as follows:
- the last maintenance of IEC 62290-1 is taken into account, in particular the changes
made for describing the external environment of UGTMS,
- the last maintenance of IEC 62290-2 is taken into account, as IEC 62290-3 is using
the requirements defined in the latter. Therefore the document reflects the deleted

1 INTRODUCTION
2 IEC 62290 standard series specifies the functional, system and interface requirements for the
3 command, control, and management systems intended to be used on urban, guided
4 passenger transport lines and networks. This series does not apply to lines that are operated
5 under specific railway regulations, unless otherwise specified by the authority having
6 jurisdiction.
7 These systems are designated herein as Urban Guided Transport Management and
8 Command/Control Systems (UGTMS). UGTMS cover a wide range of operations needs from
9 non-automated (GOA1) to unattended (GOA4) operation. A line may be equipped with
10 UGTMS on its full length or only partly equipped.
11 This series does not specifically address security issues. However, aspects of safety
12 requirements may apply to ensuring security within the urban guided transit system.
13 The main objective of this series is to achieve interoperability, interchangeability and
14 compatibility.
15 This series is a recommendation for those transport authorities wishing to introduce
16 interoperable, interchangeable and compatible equipment.

---------------------- Page: 7 ----------------------
oSIST prEN IEC 62290-3:2023
– 6 – IEC CDV 62290-3 © IEC 2023
17 It is the responsibility of the transport authority concerned in accordance with the authority
18 having jurisdiction to decide on how to apply this series and to take into account their
19 particular needs.
20 IEC 62290 series is also intended to support applications for upgrading existing signalling and
21 command control systems. In this case, interchangeability and compatibility could be ensured
22 only for the additional UGTMS equipment. Checking the possibility for upgrading existing
23 equipment and the level of interoperability is the responsibility of the transport authority
24 concerned.
25 Application of the series should take into account the differences between the various
26 networks operated in different nations. Those differences include operational and regulatory
27 requirements as well as different safety cultures.
28 This series defines a catalogue of UGTMS requirements split into mandatory and optional
29 functions. The functions used are based on the given grade of automation. Most of the
30 functions characterized as mandatory are to be considered with no condition. Some specific
31 functions have a condition to be mandatory (this condition being generally related to the use
32 of an external equipment by UGTMS). By fulfilling the requirements, a supplier can create one
33 or more generic applications including all mandatory functions and all or a subset of optional
34 functions. A generic application will achieve interoperability within the defined specific
35 application conditions. Customising a generic application will create a specific application
36 taking into account of local conditions such as track layout and headway requirements. It is
37 the choice of supplier and transport authority to add additional functions to a generic or
38 specific application. These additional functions are not described in this series.
39 According to IEC 62278, it is the responsibility of the transport authority, in agreement with
40 the authority having jurisdiction, to decide, taking into account their risk acceptance principles
41 to conduct specific hazard and risk analysis for each specific application. The safety levels for
42 the functions of each specific application have to be determined by a specific risk analysis.
43 Terms like "safety related command", "safety conditions", "safe station departure" are
44 mentioned without having performed any hazard analysis.
45 Standard series IEC 62290 is intended to consist of four parts:
46 • Part 1 “System principles and fundamental concepts” provides an introduction to the
47 standard and deals with the main concepts, the system definition, the principles and
48 the basic functions of UGTMS (Urban Guided Transport Management and
49 Command/Control Systems).
50 The three other parts correspond to the three steps (see Figure 1) required in the process of
51 specifying UGTMS and are to be used accordingly.
52 • Part 2 “Functional requirements specification” specifies the functional requirements
53 associated to the basic functions provided by Part 1, within the system boundaries and
54 interfaces as defined in Figure 3 of Part 1.
55 The FRS (Functional Requirements Specification) identifies and defines the functions
56 that are necessary to operate an urban guided transport system. Two types of
57 functions are distinguished for a given grade of automation: mandatory functions (e.g.
58 train detection) and optional functions (e.g. manage stabling). Requirements of
59 functions have the same allocation, unless they are marked otherwise.
60 • Part 3 “System requirements specifications” deals with the architecture of the system
61 and the allocation of the requirements and functions identified in Part 2 to UGTMS
62 equipment.
63 The SRS (System Requirement Specification) specifies the architecture of a UGTMS
64 system, with mandatory and optional UGTMS equipment.

IEC CDV 62290-3 © IEC 2023 – 7 –
65 • Part 4 (under consideration) “Interface specifications” deals with the definition of the
66 interfaces, as well as the data exchanged by them (FIS and FFFIS), for the
67 interoperable and interchangeable UGTMS equipment identified in Part 3.
68 For interfaces between UGTMS equipment, the logical interface or FIS (Functional
69 Interface Specification) and/or the physical and logical interface or FFFIS (Form Fit
70 Functional Interface Specification) will be considered.
71 NOTE The specific structure of Part 4 will be established to accommodate optional and mandatory UGTMS
72 equipment, and to reflect local conditions. In principle, only one FIS or/and FFFIS will be defined for the same
73 interface. However, when justified in some cases, several FISs or several FFFISs will be defined for the same
74 interface.
75
76 Figure 1 – The three-step process followed by the UGTMS standard
77 Requirements are those necessary to fulfil all operational needs for safe and orderly operation
78 requested by transport authorities without regard to technical solutions.
79 The chosen level of detail in describing requirements enables customers as well as authorities
80 having jurisdiction to be assured that generic applications delivered by different suppliers will
81 cover at least the same functionality as specified in this document.
82 Requirements which are established by this series are indicated clearly with a requirement
83 identification number related to the function to be covered.

164 4.1 Overall system architecture
165 This clause provides the general description of UGTMS architecture, the list of UGTMS
166 subsystems, the identification of interfaces between UGTMS subsystems, and between
167 UGTMS subsystems and the environment.
168 Non-functional requirements (like the ones related to performance) are described as well, in
169 addition to the main choices made in this document and having an impact on architecture.
170 Figure 2 and Figure 3 describe the UGTMS System architecture in consistency with the
171 environment described in IEC 62290-1:2014, and highlighting external interfaces with this
172 environment, and internal interfaces between UGTMS equipment.
173
174 Figure 2 – UGTMS system environment (as defined in IEC 62290-1)
175 In the rest of the document, following an architecture decision (as shown in Figure 3), the
176 Spot Transmission subsystem is considered as an independent UGTMS subsystem.

179 Figure 3 – UGTMS system architecture, external systems and external interfaces
180 It has to be noted that Figure 3 does not represent all the flows through the DCS subsystem,
181 in order to keep it readable. The direct flows through the DCS existing possibly between
182 external equipment and a UGTMS subsystem are described in subclauses 4.4, in 6.1 and 6.3.
183 It has to be noted as well that the allocation work done in Clause 6 has permitted the
184 identification of potential communication links for external equipment through the DCS, but
185 the document does not cover all of these communication links.
186 Hypotheses [H1], [H2] and [H3] in 4.2 have been applied for the determination of this system
187 architecture.
188 4.2 Hypotheses for UGTMS architecture
189 This subclause describes the major choices identified in the standard and having an impact
190 on architecture, and that result from the allocation done in 6.1, and in 6.2.
191 While Figure 3 is an architecture prepared to achieve the allocation of functions and
192 requirements defined in IEC 62290-2:2014, some allocating works are difficult on this system
193 breakdown structure level of the figure. The following hypotheses complement the
194 representation of architecture to complete the allocations (tag with “H” is added to each item
195 in preparation to link related descriptions):
196 [H1] It is assumed that the external OHMI is connected to the UGTMS subsystems via the
197 OCS. As an option, according to the decided allocation for requirements from
198 IEC 62290-2:2014, the connection can be done directly though the DCS.
199 [H2] It is assumed that the external Train HMI is directly connected to the OBS. As an option,
200 it could be through the DCS
201 [H3] The architecture and the related allocation considered in this document is the one of the
202 current state of the art which involves both WS and OBS (different approaches induced
203 by technology evolution could be considered in the future maintenance of this
204 document, such as for instance an architecture which allocates a maximum of functions
205 to OBS)
206 [H4] The duty roster, if any, is considered to be included in the Operation Planning System.
