Railways applications - Basic parameters of train detection systems - Part 2: Axle counters

This European Standard specifies parameters for the design and usage of axle counter systems.
For this, the standard specifies the technical parameters of axle counter systems associated with the magnetic
field limits for RST in the context of interoperability. In addition test methods are defined for establishing the
conformity and the performance of axle counter products.
The specified parameters are structured and allocated according to their basic references as follows:
- Axle counter system parameters
- Train based parameters
- Track based parameters
- Environmental and other parameters
Each parameter is defined by a short general description, the definition of the requirement, the relation to
other standards and a procedure to show the fulfilment of the requirement as far as necessary. An overview
on the safety relevance of each parameter is given – in the context of this European Standard – in a separate
table.
This European Standard is intended to be used to assess compliance of axle counter systems and other
forms of wheel sensors used for train detection, in the context of the European Directive on the interoperability
of the trans-European railway system and the associated technical specification for interoperability relating to
the control-command and signalling track-side subsystems.
The frequency bands and rolling stock emission limits are currently defined in the axle counter FrM as
specified in the CCS TSI Index 77.

Železniške naprave - Osnovni parametri sistemov za detekcijo vlakov - 2. del: Števci osi

Ta evropski standard določa parametre za zasnovo in uporabo sistemov števcev osi. V ta namen standard določa tehnične parametre sistemov števcev osi, povezanih z omejitvami magnetnih polj za RST v okviru interoperabilnosti. Poleg tega so določene preskusne metode za ugotavljanje skladnosti in delovanja proizvodov, povezanih s števci osi.
Opredeljeni parametri so strukturirani in dodeljeni v skladu z njihovimi osnovnimi sklicevanji, kot sledi:
– parametri sistemov števcev osi;
– parametri na podlagi vlaka;
– parametri na podlagi tirov;
– okoljski in drugi parametri.
Vsak parameter je opredeljen s kratkim splošnim opisom, definicijo zahteve, povezavo z drugimi standardi in postopkom za prikaz izpolnitve zahteve, kolikor je potrebno. Pregled varnostnega pomena vsakega parametra je v okviru tega evropskega standarda podan v ločeni tabeli.
Ta evropski standard je namenjen uporabi za oceno skladnosti sistemov števcev osi in drugih oblik senzorjev na kolesih, ki se uporabljajo za detekcijo vlakov, v okviru evropske direktive o interoperabilnosti vseevropskega železniškega sistema in povezane tehnične specifikacije za interoperabilnost, ki se nanaša na podsistema za upravljanje-vodenje in signaliziranje ob progi.
Frekvenčni pasovi in omejitve emisij železniških vozil so trenutno opredeljeni v okviru upravljanja s frekvencami, kot je določeno v indeksu 77 CCS TSI.

Introduction
The working group CENELEC/SC9XA WGA4-2 has developed the limits for electromagnetic compatibility
between rolling stock and train detection systems, specifically track circuits and axle counter systems, and
correspondingly published two technical specifications: CLC/TS 50238-2 and CLC/TS 50238-3. These limits
and associated measurement methods are based on characteristics of existing systems that are well
established and still put forward for signalling renewals by infrastructure managers.

To meet the requirements for compatibility between train detection systems and rolling stock in the future and
to achieve interoperability and free movement within the European Union, it is necessary to define a “FrM” and
a complete set of interface requirements.

Track circuits and axle counter systems, are an integral part of the CCS trackside subsystem in the context of
the Rail Interoperability Directive. The relevant basic parameters are enumerated in the CCS and LOC&PAS
TSI and specified in the mandatory Specification CCS TSI Index 77 “Interfaces between Control-Command
and Signalling Trackside and other Subsystems”. This standard refers whenever needed to the mandatory
specification.

The already published specifications CLC/TS 50238-2 and CLC/TS 50238-3 can be used to ascertain
conformity of individual train detection systems to the requirements of the TSIs and to the Notified National
Rules, which will be in place for the parameters still declared “open points” in CCS TSI Index 77.

The requirements defined in this standard are either compliant with those of CCS TSI Index 77 or can be used
as input information for the closure of open points of the CCS TSI Index 77. Where applicable, the standard
should refer to the rolling stock FrM in the TSI CCS and the parameter values defined in the CCS TSI Index
77.

130 Introduction
131 The working group SC9XA WGA4-2 has developed the limits for electromagnetic compatibility between rolling
132 stock and train detection systems, specifically track circuits and axle counter systems and correspondingly
133 published two technical specifications CLC TS50238-2 and CLC TS50238-3. These limits and associated
134 measurement methods are based on preferred existing systems which are well established and still put
135 forward for signalling renewals by infrastructure managers. To meet the requirements for compatibility with
136 rolling stock in the future (ref. ERA/ERTMS/033281) defined in the form of Frequency Management and to
137 benefit true interoperability and free movement within the Community, it is considered necessary to develop a
138 new harmonised standard to define the complete set of requirements for the target train detection system.
139 Although the demand for FM is driven by Interoperability requirements, it is independent from the drive to
140 introduce systems like ERTMS level 3 or level 2.
141
142 This European Standard is based on the current understanding of the Railway Industry experts represented at
143 WGA4-2 that track circuits and axle counter systems will continue to be the essential two train detection
144 systems for the foreseen future. The train detection systems are also seen as an integral part of CCS
145 trackside subsystem, in the context of the Rail Interoperability Directive.
146
147 This European Standard is a counter part to the TS 50238-3 which specifies – in combination with the
148 frequency management, defined in the TSI CCS Interface Document – the requirements for compatibility of
149 rolling stock. Both sides – rolling stock and axle counter systems –fulfil their requirements on the magnetic
150 field interface in relation to the TSI CCS and the corresponding standards to obtain a safe and reliable
151 operation.
152
153 In this European Standard, the defined parameters are structured and allocated according to their basic
154 references as follows:
155 - Axle counter system parameters
156 - Train based parameters
157 - Track based parameters
158 - Environmental and other parameters
159
160 Where possible, the parameters are defined as consistent with other European Standards.
161
162 Each parameter is defined by a short general description, the definition of the requirement, the relation to
163 other standards and a procedure to show the fulfilment of the requirement as far as necessary. An overview
164 on the safety relevance of each parameter is given – in the context of this European Standard – in a separate
165 table.
166
167 A table in the TSI CCS Interface document [ERA/ERTMS 033281] gives an overview on the magnetic field
168 emission levels established for individual axle counter detectors which fulfil the following two requirements:
169
170 1) Currently supported by an European Infrastructure Manager for signalling installations;
171 2) Immunity limits established following the test specification outlined in TS50238-3.

173 1 Scope
174 This European Standard is intended to specify the design and usage of Axle counter systems. It will be
175 primarily used by Manufacturers of axle counter systems and other forms of Wheel Sensors used for train
176 detection as well as by Infrastructure Managers/Infrastructure Companies and National Safety Authorities,
177 who are responsible for introducing and certifying new train detection systems.
178
179 This European Standard specifies the basic parameters of Axle Counter systems associated with the
180 magnetic field limits for RST in the context of interoperability defined in the form of Frequency Management.
181 The bands and limits currently defined in the Frequency Management are controlled by the European Railway
182 Agency.
