1 Scope
This document specifies the requirements for the rescue coupler for train sets compliant with the
Technical Specification for Interoperability Locomotives and Passenger rolling stock (TSI Loc and Pas).
This document defines the rescue coupler foreseen to connect a rescue vehicle equipped with a draw
hook, according to EN 15566:2022 and a headstock layout according to EN 16839:2022 together with
the train to be rescued equipped with a Type 10 automatic coupler according to EN 16019:2014.
Provisions going beyond the scope of this document are defined in the Technical Specification. The
Technical Specification is not a mandatory document.
This document deals with requirements and tests on rescue coupler.
The requirements on coupling interfaces of end couplers are defined in EN 16019:2014.
