End coupling (external coupling) of units

The coupling device used to couple together two (or several) units to form a train. An end coupling can be ‘automatic’, ‘semi-automatic’ or ‘manual’. An end coupling can be used for rescue purpose (see clause 4.2.2.2.4). In the context of this TSI, a ‘Manual’ coupling is an end coupling system which requires (one or several) person(s) to stand between the units to be coupled or uncoupled for the mechanical coupling of these units.
