1 Scope
The European standard specifies the requirements for the end coupler for train sets compliant with the
technical specification for Interoperability High Speed Rolling stock.
It defines the minimum interface requirements in order to allow automatic coupling (mechanical and
pneumatical) of two interoperable train sets of different types.
The herein specified interfaces of the end coupler enable the rescue of a train set in an event of a breakdown
by another interoperable trainset of different type, without the need to use an intermediate coupler adapter,
accessories or component.

references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

4 Product requirements
4.1 General requirements
The stroke requirements and the coupler length shall be taken into consideration.
4.1.1 Automatic coupler head characteristics
The coupler head (see Figure 1) of the automatic coupler shall be equipped with a pivoting coupler lock,
enabling the mechanical connection of two vehicles. The coupler lock consists of the following parts: hooked
plate, coupling link, central pivot, tension springs, spring bearing, and ratchet with stem guide. In order to
ensure a maximum gathering range, both vertically and horizontally, the coupler head shall be provided with
male cone, female cone and gathering horn, such that the couplers can be aligned and centred also in curves
and in case of vertical mismatch. The coupler head dimensions shall be according to Annex A.
Tolerances for dimensions shall be according to ISO 2768-1, tolerance class mH, unless otherwise specified
in this standard.

Spring bearing and stem guide may be a combined element.

b female cone 3 coupling link pin 7 spring bearing
c coupler face 4 hooked plate 8 stem guide
1 coupling link 5 central pivot 9 coupler head casing
Figure 1 — Principle arrangement of coupler head
When coupled, the coupler lock elements are subjected to tensile load and form a parallelogram ensuring an
equilibrium of forces and an equal load distribution onto both coupling links. The equilibrium of forces prevents
involuntary unlocking of the coupler locks and reduces wear.
Compressive loads are transmitted through the flat coupler faces of the coupler heads.
The automatic coupler shall be designed to withstand the following loads without permanent deformation:
6

---------------------- Page: 8 ----------------------
oSIST prEN 16019:2010
prEN 16019:2009 (E)
 maximum tensile load = 1 000 kN;
 maximum compressive load = 1 500 kN.
These values are for normal operating conditions. If the coupler is used only for rescue conditions, lower
values are allowed.
When coupled, the coupler locks ensure a nearly slack-free connection between the automatic couplers. The
coupler lock play is the distance between the coupler faces of two coupled coupler heads. Coupler lock play
shall not exceed 0,8 mm per coupler lock.
4.1.2 Coupling system positions
The coupling system has three operating positions:
4.1.2.1 Ready-to-couple position
In the ready-to-couple position, the coupling link shall be retracted and lie close to the edge of the male cone
and the ratchet shall hold the hooked plate. In this position, the ratchet shall project over the side of the
coupler head casing and shall be engaged with the catch of the stem guide. In the ready-to-couple position,
the tension springs are loaded. See Figure 2.

Figure 2 — Ready-to-couple position
4.1.2.2 Coupled position
As the coupler faces mate, the male cones entering the female cones shall press the stems backwards, in
order for the ratchets to be released. After the ratchets have been released, the tension springs shall turn the
hooked plates counterclockwise until they reach the stops in the coupler head casings. In the coupled
position, the coupler locks are engaged. See Figure 3.
