Railway Applications - Track - Performance requirements for fastening systems - Part 7: Fastening systems for switches and crossings, check rails, insulated rail joints and rail expansion devices
This European Standard specifies performance requirements for special fastening systems, in categories A - E as specified in EN 13481-1:2012, 3.1, for switches and crossings and check rails. These types of rails are those which are secured within the overall fastening system (not independently fixed to the bearers) on wood, concrete and steel bearers, in ballasted track and on slab track, and which have maximum axle loads and minimum curve radii in divergent track in accordance with Table 1. Table 1 - Fastening category criteria Category Maximum design axle load Minimum curve radius
kN m
A 130 40
B 180 80
C 260 150
D 260 400
E 350 150
NOTE The maximum axle load for Categories A and B does not apply to maintenance vehicles.
The requirements apply to fastening systems for rail sections included in the EN13674 series of standards (excluding 49E4).
This standard is not applicable to fastening systems for other rail sections or rigid fastening systems used on running rails.
This standard is for type approval of complete fastening systems.

5 Requirements to be determined by laboratory testing
5.1 Special fastenings for slide baseplates
5.1.1 General
The requirements set out in this subclause are applicable to fastenings for slide baseplates in S&C.
NOTE Where hollow bearers are used, specific requirements for the fastening system are set out in
EN 16431:2014.
5.1.2 Specimens for laboratory testing
For fastenings intended for use on ballasted track, the test specimen shall consist of the slide baseplate
mounted on part of a bearer and assembled with a short length of the stock rail.
Fastenings intended for use on ballastless track shall be tested on a supporting element as set out in
EN 13481-5:2022 and assembled with a short length of the stock rail.
Where a number of similar slide baseplates need to be considered, representative configuration(s) shall
be selected as Reference Configuration(s) as set out in Annex B, and shall be tested in a laboratory to
demonstrate compliance with the requirements set out in 5.1.3 to 5.1.9 below.
Compliance of other similar configurations of slide chair may be demonstrated as follows:
a) The differences between the modified configuration of slide chair and the Reference Configuration
shall be identified and listed.
b) Compliance with the requirements of this standard shall be demonstrated by assessing the effects of
those differences on each requirement by means of calculation or supplementary testing.

5.1.4 Clamping force
This shall be determined by the procedure in EN 13146-7:2019. The result shall be reported.
This requirement is not applicable to web support fastening systems.
5.1.5 Assembly and pad stiffness

static stiffness and assembly low frequency dynamic stiffness at 5Hz shall be measured in accordance
with EN 13146-9:2020.
Stiffness testing of pads is not a requirement for type approval of the fastening but may be used to provide
guidance for other tests e.g. quality control. If required, pads shall be tested in accordance with
EN 13146-9:2020.
Loads are given in Table 2 for testing pads and for testing complete fastening assemblies.

This shall be determined by the procedure in EN 13146-4:2020. The switch rail does not need to be
included in the assembly for testing.
NOTE Support may have to be provided to ensure the load on the running rail remains central during the test.
5.1.6.2 Test loads
The maximum applied load (P /cos α) kN and values of X and α shall be determined from Table 3 in

5.1.6.3 Evaluation of test performance
The following measurements shall be performed before and after repeated loading. The change in
performance (increase or decrease) shall not exceed the values shown.
— Change in longitudinal rail restraint ≤ ± 20 %;
— change in assembly stiffness ≤ ± 25 %;
— change in clamping force ≤ ± 20 %.
The requirement for change in assembly stiffness is not applicable to fastening systems with a static
stiffness ≥ 300 MN/m.
5.1.7 Electrical resistance of fastening system and bearer
If the purchaser requires the fastening system to provide electrical insulation when used on concrete
bearers, ballastless track or steel bearers, this shall be not less than 3 kΩ when measured in accordance
1
with EN 13146-5:2012 . The user may specify a higher value for use with certain track circuits.
In the case of steel bearers, one only of the three test bearers shall be tested before and after the repeated
loading test.
NOTE This requirement relates to signalling currents only, not to traction currents. Guidance on traction
currents is given in EN 50122-2.

5.1.8 Effect of exposure to severe environmental conditions
Following exposure to the salt spray test in accordance with EN 13146-6:2012 the fastening assembly
shall be capable of being dismantled, without failure of any component, and re-assembled using manual
tools provided for this purpose.
5.1.9 Cast-in and glued-in fastening components
This requirement shall apply to fastening systems for use on concrete bearers, polymeric composite
bearers and concrete slabs only. A vertical load test shall be performed using the procedure described in
EN 13146-10:2017. Three bearers or three blocks, each incorporating cast-in or glued-in components for
one fastening assembly, shall be selected for testing and one cast-in component in each bearer or block
shall be subjected to this test.
The proof load to be applied may be specified by the designer of the track system. If no such requirement
is specified the proof load applied in each test shall be 60 kN if there are two cast-in or glued-in
components per rail seat, 40 kN if there are three cast-in or glued-in components per rail seat and 30 kN
if there are four or more cast-in or glued in components per rail seat.
After the test there shall be no evidence of damage to the fastening component or supporting element
that could result in a loss of integrity or durability of the system. Localized spalling of a concrete surface
immediately adjacent to the fastening insert is not to be considered to be a reason to reject the system.
5.2 Check rail supports
5.2.1 General
The requirements set out in this standard are applicable to check rail and wing rail supports in S&C.
Unless it is stated otherwise, they also apply to check rail supports used in sharp curves in plain line. They
are applicable to check rail supports which form a part of the fastening system for the running rail and to
independent check rail supports.
NOTE Where hollow bearers are used, specific requirements for the fastening system are set out in
EN 16431:2014.
5.2.2 Specimens for laboratory testing
For fastenings intended for use on ballasted track, the test specimen shall consist of the check rail support
mounted on part of a bearer and assembled with a short length of the running rail and check rail.
Fastenings intended for use on ballastless track shall be tested on a supporting element as set out in

5.2.3 Longitudinal rail restraint
For check rail supports which incorporate a fastening for the running rail, when measured by the
procedure in EN 13146-1:2019, the longitudinal rail restraint of the running rail shall be not less than
7 kN when rail pads are used under stock rails. When no pads are used, the longitudinal rail restraint
shall be not less than 5 kN.
On structures such as long bridges, the longitudinal force transmitted between the track and the structure

may be calculated by the method in EN 1991-2:2003 . The value of F measured in accordance with
max
