European foreword
This document (EN 15566:2016) has been prepared by Technical Committee CEN/TC 256 “Railway
applications”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by March 2017, and conflicting national standards shall
be withdrawn at the latest by March 2017.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 15566:2009+A1:2010.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive 2008/57/EC.
For relationship with EU Directive 2008/57/EC, see informative Annex ZA, which is an integral part of
this document.
Modifications
Compared with EN 15566:2009+A1:2010 the following main changes have been done:
a) checking and revision of Clause 2 – Normative references;
b) modification in Clause 3 – working capacity (3.8) was deleted and intermediate coupling system for
permanent coupled wagons now defined as permanent coupling system;
c) in Clause 4, requirements for compressive loads for draw hook and draw gear rationalised and
explained;
d) in Clause 7,
