This document defines the rescue coupler foreseen to connect rescue vehicle equipped with draw hook, according to EN 15566 together with the train to be rescued equipped with Type 10 automatic coupler according to EN 16019.

This document is applicable to vehicles equipped with buffers and screw coupling systems.
In order to allow operation and coupling of trainsets or vehicles, this document specifies the
defined free space for the shunter called the "Berne rectangle" and the necessary free space for
the installation of the rescue coupler.
This document specifies the location, fixing and free spaces on the headstock of:
- buffers;
- screw coupling systems;
- end cocks;
- pneumatic half couplings;
- connections for electric cables.

This document defines the requirements for buffers with 105 mm, 110 mm and 150 mm stroke for vehicles or units which use buffers and screw coupling. It covers the functionality, interfaces and testing procedures, including pass fail criteria, for buffers.
NOTE 1   Typically, buffers with a stroke of 105 mm are used on freight wagons and locomotives, buffers with a stroke of 110 mm are used on coaches and locomotives and buffers with a stroke of 150 mm are used on freight wagons.

The properties for the energy absorbing function are defined in EN 15227 and the requirements specified in Clause 7 for tank wagons for dangerous goods are not applicable to the buffers of these locomotives and passenger coaches.
Diagonal buffers are excluded from this document.
For the crashworthy buffers of locomotives, cab cars or passenger coaches according to EN 15227, and tank wagons for dangerous goods or buffers which form part of a combined system consisting of a special buffer and a deformation element, interchangeability with freight wagon buffers is not required, and therefore the requirements of 5.3 (Buffer dimensions) do not apply, those of 5.4 (Mechanical characteristics of buffers) and 5.6 (Marking) apply with restrictions.
NOTE 2   For tank wagons subjected to dangerous goods regulation see [35].

The purpose of this document is to analyse the conducted investigation and evaluation of lateral displacement and buffer overlap between each two specified vehicles of different train sets for defined running cases in curves.
For this purpose, the types of vehicles defining the train sets and different operating conditions are specified. Position of the vehicles on the track at the moment of maximum lateral displacement (minimum buffer overlap) is recorded during the calculation.
The worst cases of lateral displacement and buffer overlap between two coupled vehicles as well as relation to formulae in EN 15551:2009 are analysed.
