Overview

prEN 16019 - "Railway applications - Automatic coupler - Performance requirements, specific interface geometry and test method" (CEN) defines minimum interface, performance and test requirements for end automatic couplers on High Speed rolling stock intended to be interoperable across European train sets. The draft standard targets latch‑type automatic couplers (also referenced as Scharfenberg system type 10) and specifies mechanical and pneumatic coupling interfaces so two different interoperable train sets can couple automatically - including rescue operations - without adapters or auxiliary components.

Key topics and technical requirements

• Scope and intent

  • Minimum interface geometry and performance to allow automatic mechanical and pneumatic coupling of different trainset types.
  • Enables rescue/towing of a disabled trainset by another interoperable unit.

• Coupler design and components

  • Definitions of coupler head, hooked plate, coupling link, central pivot, ratchet, tension springs and casing.
  • Requirement for male/female cones and gathering horns to allow alignment in curves and vertical mismatch.

• Mechanical performance

  • Design loads for normal operation: maximum tensile load = 1 000 kN, maximum compressive load = 1 500 kN (lower values allowed if used only for rescue).
  • Maximum coupler lock play: ≤ 0.8 mm per coupler lock to ensure nearly slack‑free connection.
  • Minimum automatic coupling speed: 0.6 km/h.

• Pneumatic coupling

  • Automatic connection of brake pipe, main reservoir pipe, and uncouple pipe during mechanical coupling; valves operated by the central pivot to open/close pipes as required.
  • Air‑pipe interface dimensions and details are specified in Annex C.

• Operating envelope

  • Specified gathering range (horizontal and vertical tolerances) and capability to negotiate curves (e.g., 150 m radius and S‑curves with minimum straight).

• Tests and verification

  • Type tests: strength (tensile/compression), dimensional checks, gathering range tests.
  • Routine tests: visual inspection, dimensional, function tests.
  • Normative Annexes: Interface geometry (Annex A), lock‑play measurement (Annex B), air pipe connections (Annex C).

Applications and users

prEN 16019 is relevant for:

• Rolling stock designers and car builders (mechanical and pneumatic interface design)
• OEM coupler manufacturers and suppliers
• Railway operators and fleet planners for interoperability and rescue procedures
• Maintenance and inspection teams (routine tests and acceptance checks)
• Certification bodies and procurement authorities ensuring compliance with interoperability requirements

Related standards and compliance

• References ISO 2768‑1 for tolerances.
• Supports essential requirements of EU Directive 2008/57/EC (see informative Annex ZA).

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:
 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.
