This document specifies measurement methods and conditions to obtain reproducible and comparable exterior noise emission levels and spectra for all kinds of vehicles operating on rails or other types of fixed track, hereinafter conventionally called “unit”.
This document is applicable to type testing of units.
It provides measurement procedures for vehicle exterior noise (in general, a vehicle type test is carried out using only a selected subset of these tests):
— when the vehicle is moving at constant speed;
— when the vehicle is accelerating or decelerating;
— when the vehicle is stationary in different operating conditions.
It does not include all the instructions to characterize the noise emission of the other infrastructure related sources (bridges, crossings, switching, impact noise, curving noise, etc.).
This document is not applicable to:
— the noise emission of track maintenance units while working;
— environmental impact assessment;
— noise immission assessment;
— guided buses;
— warning signal noise.
The results may be used, for example:
— to characterize the exterior noise emitted by units;
— to compare the noise emission of various units on a particular track section;
— to collect basic source data for units.
NOTE Additional guidance is provided in Annex D for measurements in the specific case of light rail vehicles.

This document specifies the methodology to define the train related braking model and required brake on-board parameters to enable speed and distance monitoring for trains equipped and operated on railway lines using ETCS Baseline 3.
This document is only applicable for ETCS Gamma braking model trains (i.e. the train is said to be a “gamma” train). This document does not specify the way these parameters are transferred to and can be used by the ETCS on-board system (e.g. during start of mission - SoM).
The ETCS “conversion models” are not covered by this document and are described in EN 16834:2019, Annex F. The ETCS “conversion models” are intended for use with trains where the braking performance is expressed using braked weight percentages (“lambda” train).
Any trackside related input parameters, including national values, are not covered in this document. Information can be found in the SUBSET-026 (see [11]).
