Introduction

The aim of this document is to describe the implementation of the European Vehicle Number

(EVN) of the railway rolling stock in an electronic format via the ISO/IEC 18000-63 UHF Radio

Frequency Identification (RFID) technology in order to enable a consistent approach for an

interoperable implementation.

Furthermore, the authors of this document recognize that there exists today rolling stock which

uses other numbering schemes than the EVN, for example in the Baltic States. Some of these cases

are addressed in this document for informative purposes.

5 Concept

The concept is to identify rolling stock automatically based on UHF RFID tags. The main focus of

this standard is to clarify applications using fixed track side readers.

Each RFID tag contains a globally unique asset reference encoded according to the Clause 7.

This standard aims to achieve global uniqueness and interoperability.

RFID tag content used in rolling stock identification shall not overlap with any other globally

unique identifier coded into RFID tags.
6 RFID tag location
6.1 General

Each vehicle shall be tagged with two UHF RFID tags according to ISO/IEC 18000-63.

While all other encoded information on the two tags per vehicle is 100 % identical, the content of

the two tags differ only by an encoded end/side information. On one tag per vehicle the encoded

end/side information is “1”, on the other one the encoded end/side information is “2”. For further

details see Clause 7.

The RFID tag location is to be implemented as in the subclauses 6.2 and 6.3. If this is not possible,

the implementation should be done into a location closest to the area fulfilling the functional

requirements set in this standard.

The physical interactions between the reader and the tag, the protocols and the commands, and

the collision arbitration schemes, shall conform to ISO/IEC 18000-63.

Subclause 6.4 explains how to use/relate the end/side information on the tag in order to create a

correlation between them and the already existing physical agreed end/side markings of the

vehicle.

Figure 1 — Allowed range of vertical tag positions

In Figure 1 above, A1 and A2 are respectively the minimum and maximum height above rail for

positioning the centres of the tags in all conditions of wagon loading and suspension movement:

A1 = 500 mm

A2 = 1300 mm for vehicles with maximum speed > 100 km/h, 1800 mm for vehicles with

maximum speed < = 100km/h.

When planning reader installations, it is recommended to take in account that there might be

existing vehicle implementations outside this range

If the installation is done outside the range A1 - A2, the trackside reading performance as in the

paragraph 8.2 Tag performance requirements cannot be guaranteed.
6.3 Horizontal tag location

The horizontal range of allowed tag positions for vehicle ends which cannot be leading on the

main line, is limited from the left vehicle end to the vehicle centre axis (see area B1 in Figure 2).

Regarding the horizontal range of allowed tag positions for vehicle ends which can be leading on

the main line, the tag shall be installed in relation to the horizontal axis in the area B2 in Figure 3

respectively Figure 4.

On vehicles without bogies (for example two-axle wagons or two-axle shunting engines (see

Annex A)) which have vehicle ends, that can be leading on the main line, the RFID tags at these

vehicle ends shall be installed at least 0,6 m behind the first axle towards the centre of the vehicle

(see area B2 in Figure 5).

Note 1 When planning reader installations, please take into account that there might be older vehicle

implementations outside this range.

Note 2 The limitation of horizontal tag positions for vehicle ends which can be leading on the main line

is meant to allow reader layouts with one reader and one axle counter for tracks with alternating direction

of traffic (see Annex B).

6.4 Defining the orientation of the vehicle
6.4.1 Introduction

The Clause 6.4 gives information on how to identify orientation of a vehicle. Clause 6.4.3 is

mandatory for vehicles constructed according to EN 13775-1. For all others Clause 6.4.4 provides

a recommendation on how to use the end/side indications on the tag to create a correlation

between them and the physical characteristics of the vehicle. On those vehicles, the end/side

indicator of the tag should be correlated to the first possible element of the following hierarchy

of vehicle characteristics:
1. Possibly existing vehicle end markings;
2. Possibly existing vehicle side markings;
3. Possibly existing axle numbering schemes.
6.4.2 Flowchart for defining the vehicle end/side naming

The implementer shall work through the sections below in the order given until one is found

which matches the particular vehicle under consideration (see Figure 6).

6.4.3 Vehicle with existing end / side markings according to the EN 13775 series

Each vehicle constructed according to the EN 13775 series has a constructional end 1, an end 2,

a left side, and a right side according to Figure 7. The end/side information is either physically

marked on the vehicle or at least apparent from the dedicated constructional drawings.

On vehicles for which any other end/side markings already exist or without any existing end/side

physical vehicle end, respectively (Figure 10).

If no meaningful correlation to existing end or side markings can be created, whenever possible,

the tag with the end/side indicator 1 should be mounted closest to the axle of the lowest number,

which is in most cases 1.

7 Data on the tag
7.1 General

The RFID tag holds a globally unique identification with an asset reference based on the European

Vehicle Number and a side/end indicator. Implementation guidelines may specify the preferred

identification scheme used by a given railway infrastructure or implementation.

Data length and data structure are defined by the content of StoredPC as described in

ISO/IEC 18000-63. The number of 16 bit words is stored in the length field, bits 10h to 14h. The

range of the length is 0 to 31 words i.e. 0 to 496 bits (see Annex D). The toggle bit 17h specifies

the data structure. If bit 17h is 0 then the application is referred to as GS1 data structure. If bit

17h is 1 then the application is referred to as ASC data structure.
7.2 GS1 data structure
7.2.1 General

An EPC/RFID tag’s EPC memory bank (MB 01) includes an Electronic Product Code (EPC), which

is a globally unique identifier for the physical object to which the tag is attached, as well as control

---------------------- Page: 22 ----------------------
SIST EN 17230:2021
