Railway applications - Rolling stock - Head stock layout

This European Standard defines the layout of the devices installed on the headstock of vehicles equipped with buffers and screw coupler in order to allow operation and coupling of trainsets or vehicles including rescue condition.
The European Standard deals with the defined free space for the shunter called the "Berne rectangle" and the location on the headstock of:
—   buffers including boundary conditions;
—   screw coupling systems;
—   head cocks;
—   pneumatic half coupling;
—   (optional) steps and handrails on the front beam (e.g. for use by shunters);
—   connection for electric cables;
It also defines the fixing of certain equipment on the head stock (buffers, screw coupling, connections for brake system and electric system) and the calculation of the width of the buffer plates.
All dimensions given in this European Standard are nominal values.

5 Buffers
5.1 General
The following requirements apply to vehicles equipped at least at one end with two buffers according to
EN 15551, fixed symmetrically to the longitudinal centre line of the vehicle.
5.2 Position of buffers on the headstock
5.2.1 Distance between buffers
The standard distance between buffer centrelines shall be nominally according to Table 1.
Table 1 —Track gauge and distance between buffer centrelines
Track gauge Distance between buffer centre lines
mm mm
1 435 1 750 ± 10
Interchangeable 1 435/1 524 1 790 ± 10

1 524 1 830 ± 10
1 600 1 905 ± 3
1 668 1 850 ± 10

It is permitted for dual gauge units (interchangeable wheel sets) intended for running between
standard gauge network 1 435 mm and broad gauge networks to have a different value of the distance
between buffer centrelines (e.g. 1 850 mm), provided that full compatibility with buffers for standard
1 435 mm gauge is ensured.
Buffers shall be sized so that in horizontal curves and reverse curves, it is not possible for vehicles to
lock buffers. The minimum horizontal overlap between buffer heads in contact shall be 25 mm.
5.2.2 Height of buffers above top of the rail
The height b of the centre line of the buffers to the top of the rail shall be in all loading and wear
conditions in accordance with Table 2.

5.3 Buffer fixing
5.3.1 Vehicles without crashworthy buffer systems
The buffers shall be attached to the vehicle headstock.
The screws shall be M 24, grade 8.8, and self-locking nuts, grade 8, shall be used. The screws shall have
a threaded projection of at least three threads.
The recommended tightening torque should be 690 Nm.
For wagons, distance between holes shall be in accordance with Figure 3.
For wagons fitted with 150 mm stroke buffers, pins in the headstock, which indicate that this kind of
buffer shall be used, shall be located at the right side of the each buffer (looking at the buffer head) as
shown in Figure 3, item 1, Section A – A. The protrusion of the pin shall be at minimum 20 mm.
NOTE To avoid confusion of buffers with different strokes, buffers with 150 mm stroke therefore have an
opening at their right side, buffers with 105 mm stroke do not have this opening.
The hole spacing (280 × 160) mm for freight wagons should also be used for passenger coaches, vans
and locomotives.

Vehicles that use crashworthy buffers or buffers which form part of a combined system consisting of a
special buffer and a deformation element may have a different mounting configuration (e.g. position of
flange, thread diameter, quantity of screws and their position).
NOTE These vehicles are locomotives, driving trailers or passenger coaches according to EN 15227 or tank
