Overview

SIST EN 302 609 V2.1.1:2017 is a harmonised European standard developed by SIST, based on ETSI EN 302 609 V2.1.1 (2016-12). It specifies the essential technical requirements for radio equipment used in Euroloop railway systems. The standard supports conformity with Article 3.2 of the Radio Equipment Directive 2014/53/EU, focusing on the efficient use of radio spectrum and the avoidance of harmful interference.

Euroloop is a short-range device (SRD) system designed as a wayside transmission unit using magnetic coupling technology. It plays a pivotal role in train-to-trackside communications, providing continuous data transmission that enhances the safety and reliability of modern railway operations.

Key Topics

• Scope of Application:
  The standard applies to two main equipment types within Euroloop systems:

  • On-Board Equipment (OBE): Receives Euroloop signals through a dedicated antenna installed on rail vehicles.
  • Track-Side Equipment (Euroloop): Transmits Euroloop signals from units positioned in the foot of the rail.

• Frequency Operation:
  Euroloop transmission systems operate in specific radio frequency bands compliant with EC Decision 2013/752/EU and ERC Recommendation 70-03:

  • OBE receive frequency: 11.1 - 16.0 MHz
  • OBE transmit frequency: 27.09 - 27.10 MHz
  • Euroloop receiver/transmitter uses the reciprocal bands accordingly.

• Essential Requirements:
  To demonstrate compliance with Directive 2014/53/EU, the standard details requirements for:

  • Efficient spectrum use: Reducing risk of interference and ensuring reliable communication.
  • Transmitter and receiver conformance: Including field strength, unwanted emissions, co-channel rejection, blocking, and sensitivity.
  • Testing and measurement procedures: For both radiated and conducted emission limits, with defined measurement uncertainties and environmental test conditions.

Applications

The primary application of SIST EN 302 609 V2.1.1:2017 is in railway signalling and communication systems, specifically those deploying the Euroloop technology within the European Railway Traffic Management System (ERTMS) and European Train Control System (ETCS). Through precise technical criteria, the standard ensures interoperability and safe integration of radio-based communication between trackside and train-borne equipment.

Practical scenarios include:

• On-board receivers that reliably interpret Euroloop signals as trains pass over trackside units, supporting train control and signalling.
• Trackside transmitters that communicate movement authority, speed restrictions, and positioning information to passing trains.
• Compliance assessment for railway equipment manufacturers, test laboratories, and railway infrastructure managers implementing or upgrading to Euroloop-based systems.

Related Standards

Several related standards and directives inform or complement SIST EN 302 609 V2.1.1:2017:

• Directive 2014/53/EU: Sets out essential requirements for radio equipment in the EU, focusing on spectrum use and electromagnetic compatibility.
• EC Decision 2013/752/EU: Regulates frequency allocation for short-range devices.
• ERC Recommendation 70-03: Provides harmonisation guidelines for SRD band use across Europe.
• CENELEC EN 50121-2: Addresses electromagnetic compatibility for railway applications, including emission limits for railway systems.
• ERTMS/ETCS SUBSET-044 and SUBSET-103: Define the functional and testing specifications for Euroloop equipment.
• ETSI EN 300 330-1: Lays out test methods for SRD operating in the relevant frequency bands.

By adhering to SIST EN 302 609 V2.1.1:2017 and related standards, stakeholders ensure compliance, safety, and interoperability in modern railway environments deploying Euroloop communications.

Introduction
The Euroloop communication system is defined by the specifications [1] and [2] of the UNISIG consortia.

ETSI
6 ETSI EN 302 609 V2.1.1 (2016-12)
1 Scope
The present document covers the technical requirements for radio transmitters and receivers used in the Euroloop
transmission system. The system is used in railway systems.
The present document applies to the following equipment:
1) The On-Board Equipment (OBE) receiving the Euroloop signal and the OBE comprises a receiver fitted with a
dedicated antenna.
2) The Track-Side Equipment (Euroloop) transmitting the Euroloop signal that is always installed in an inner or
outer foot of a rail.
The Euroloop transmission system operates in frequency bands listed in table 1 in accordance with the EC Decision
2013/752/EU [i.2], and ERC Recommendation 70-03 [i.3], annex 4.
These radio equipment types are capable of operating at the following frequencies as given below in table 1.
Table 1: Radio communications frequencies
Radio communications frequencies
OBE receive frequency band 11,1 -16,0 MHz
OBE transmit frequency band 27,09 - 27,10 MHz
Euroloop receiver frequency band 27,09 - 27,10 MHz
Euroloop transmit frequency band 11,1 -16,0 MHz
Euroloop transmit modulation BPSK, DSSS chip rate 4,516 MHz

The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the
efficient use of radio spectrum in order to avoid harmful interference.
