Deliverable 5.2 Technical Specifications of Wagon and Locomotive DAC up to Level 5 (V2)

This document outlines the functional and where needed the mechanical requirements needed for an interoperable design of the Digital Automatic Coupler for freight. The document covers both DAC and Hybrid DAC/Hook couplers to be used in the rail freight segment. The requirements are trying to strike a balance between mechanical and functional requirements, which allows for future innovation and development within the given area.

The document was compiled by using existing peer reviewed standards and the input from technical experts from the main suppliers of automatic couplers within the European Union and from operators and owners of rail vehicles. The draft document was reviewed in open sessions within the FA5 to gather inputs from all stake holders.

The method of verification of the requirements set out in this document are to be found in FP5-TRANS4M-R Deliverable 5.3 – Validation/Test Procedures of Wagon and Locomotive DAC up to Level 5.
