SIST EN 50121-3-1:2017/A1:2019

Railway applications - Electromagnetic compatibility - Part 3-1: Rolling stock - Train and complete vehicle

This European Standard specifies the emission and immunity requirements for all types of rolling stock. It covers traction stock, hauled stock and trainsets including urban vehicles for use in city streets. This European standard specifies the emission limits of the rolling stock to the outside world.
The scope of this part of the standard ends at the interface of the rolling stock with its respective energy inputs and outputs. In the case of locomotives, trainsets, trams etc., this is the current collector (pantograph, shoe gear). In the case of hauled stock, this is the AC or DC auxiliary power connector. However, since the current collector is part of the traction stock, it is not entirely possible to exclude the effects of this interface with the power supply line. The slow moving test has been designed to minimize these effects.
There may be additional compatibility requirements within the railway system identified in the EMC plan (e.g. as specified in EN 50238).
Basically, all apparatus to be integrated into a vehicle meet the requirements of EN 50121-3-2. In exceptional cases, where apparatus meets another EMC Standard, but full compliance with EN 50121-3-2 is not demonstrated, EMC is ensured by adequate integration measures of the apparatus into the vehicle system and/or by an appropriate EMC analysis and test which justifies deviating from EN 50121-3-2.
Electromagnetic interference concerning the railway system as a whole is dealt with in EN 50121-2.
These specific provisions are to be used in conjunction with the general provisions in EN 50121-1.
The frequency range considered is from 0 Hz (DC) to 400 GHz. No measurements need to be performed at frequencies where no requirement is specified.

Overview

EN 50121-3-1:2017/A1:2019 is a CLC (CENELEC) harmonized European standard for railway applications - electromagnetic compatibility (EMC) focused on rolling stock: trains and complete vehicles. It specifies the emission and immunity requirements for all types of rolling stock (traction stock, hauled stock, trainsets and urban vehicles) and defines how vehicles must limit electromagnetic disturbance to the outside world. The standard covers the interface of rolling stock with its energy inputs/outputs (e.g., pantograph, shoe gear, auxiliary power connectors) and addresses frequencies from 0 Hz (DC) to 400 GHz. Amendment A1:2019 updates the 2017 edition and aligns the document with the EU EMC framework.

Key Topics and Requirements

• Emission limits and immunity requirements for rolling stock to ensure safe operation and minimal interference with external systems.
• Scope of interface: requirements stop at the vehicle’s energy interfaces (current collector or auxiliary connectors), while acknowledging coupling effects at those interfaces.
• Frequency range: full coverage from 0 Hz to 400 GHz; no measurements required where no requirement is specified.
• Measurement considerations: includes provisions (e.g., the slow moving test) to minimize power-supply coupling effects during testing.
• Equipment integration: on-board apparatus should comply with EN 50121-3-2; where other EMC standards apply, adequate integration measures, analysis or tests must justify deviations.
• System-level compatibility: electromagnetic interaction affecting the railway system as a whole is covered in EN 50121-2; general provisions are in EN 50121-1.
• Regulatory linkage: supports conformity with Directive 2014/30/EU (EMC Directive) as referenced in Annex ZZ.

Applications and Who Uses It

• Rolling stock manufacturers and designers for vehicle EMC specification and design validation.
• System integrators and electrical engineers integrating traction, auxiliary and on-board equipment.
• EMC test laboratories and certification bodies conducting emissions and immunity testing.
• Railway operators and infrastructure managers assessing vehicle compatibility within EMC plans (e.g., EN 50238).
• Procurement and compliance teams requiring harmonized standards for acceptance and regulatory conformity.
