Introduction
This document covers the on-track testing for acceptance of the running characteristics of railway vehicles
equipped with a cant deficiency compensation system and/or vehicles intended to operate with a higher cant
deficiency than stated in EN 14363:2005, Annex G. It was established by Working Group 10 Vehicle/Track
Interaction of CEN Technical Committee 256 Railway Applications as a supplement to EN 14363, which is
related to the acceptance of railway vehicles with conventional curve speeds. It is foreseen to implement the
regulations of this standard in a revision of EN 14363.
The establishment of this document was based on existing rules, practices and procedures. The following
principles were applied:
1) The railway system requires comprehensive technical rules in order to ensure an acceptable
interaction of vehicle and track.
2) Due to the numerous national and international regulations new railway vehicles had to be tested and
homologated before putting them into service. In addition, existing acceptance had to be checked
when operating conditions were extended.
3) In view of the increasing significance of international traffic, in particular of high speed traffic, the
standardization of existing regulations is required. In some cases, additional rules are required as
well. An update of existing regulations is also needed due to the considerable progress achieved in
the field of railway-specific methods for measuring, evaluation and data processing.
4) It is of particular importance that the existing level of safety and reliability is not compromised even
when changes in design and operating practices are demanded, e.g. by the introduction of higher
speeds, higher wheel forces, etc.
This document takes account of the present state of the art which is generally applicable for test procedures
and the evaluation of 'on-track' tests.
This document is derived in essential parts from UIC 518-1 which has not yet been fully validated by
experience.
The Working Group is aware that the combination of the test conditions is not always achievable. In some
cases, the existing regulations may require exceptions for which justification will be provided to the
acceptance body. In this event, the conditions which are not fulfilled will be identified.
The Working Group expects that existing shortcomings will be recognized in further investigations and during
frequent application of the rules.

1 Scope
This document regulates the testing for acceptance of the running characteristics of freight vehicles with static
wheel loads higher than 112,5 kN and up to 125 kN.
All requirements of EN 14363 are applicable with some adaptations concerning:
 the conditions of line tests ,
 limit values for some assessment quantities.
Only differences for the special cases are listed.
The testing of the running characteristics applies principally to all freight vehicles, which operate without
restriction on standard gauge tracks (1 435 mm).
NOTE 1 The testing of the running characteristics of:
 railways with different track layout ,
 railways with non-standard gauge tracks
can be conducted by analogy with this document.
The testing of running characteristics is part of the type testing of vehicles which
 are newly developed ,
 have had relevant design modifications, or
 have changes in their operating regimes.
The testing and acceptance of running characteristics refers to the complete vehicle including the running
gear. If a running gear, which has already been tested and accepted, is used under a vehicle body of another
design, this is considered a design modification. The procedure as described in EN 14363:2005, 5.2 is used.
NOTE 2 In addition to the testing of running characteristics for the acceptance of vehicles, the regulations can be
generally applied in other technical tasks, e.g.:
 the checking for compliance against development contracts ;
 the optimization of components, vehicles or running gear ;
 the testing of influences, influencing parameters and relationships of dependence ;
 the monitoring of track or vehicles in operational use .
The application of the full method and the stated limit values reflects (unrestricted) international operation.
Testing for acceptance of vehicles is based on some reference conditions of track. If these are not respected
on certain lines, appropriate measures will be taken (speed modifications, additional tests, etc.).
For national or multinational operations the infrastructure managers concerned may authorize variations to the
defined conditions. Permissible deviations are indicated in this document.
It is allowed to deviate from the rules laid down if evidence can be furnished that safety is at least the
equivalent to that ensured by complying with these rules.

2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

vehicles - Testing of running behaviour and stationary tests
3 Terms and definitions
For the purposes of this document, the terms and definitions in EN 14363 apply.
4 Stationary tests
For stationary tests the requirements of EN 14363 shall apply.
5 On-track tests
5.1 General
For the acceptance of a freight vehicle with static wheel loads higher than 112,5 kN and up to 125 kN the
following modifications of the procedure defined in EN 14363 shall be respected:
 The simplified measuring methods are only applicable for extensions of acceptance without extension of
cant deficiency. Especially the operation conditions of freight wagons with axle loads ≤ 22,5 kN with
higher cant deficiency (and speed) require also tests according to EN 14363 with the full test procedure
and the normal measuring method.
 The admissible cant deficiency and speed are lower than for the axle loads defined in EN 14363.
 For the track loading parameters Q and Q new limit values are defined under defined conditions of track
qst
design.
 For extensions of acceptance the choice of the on-track test type and the measuring method is depending
on a new defined parameter χχχχ of the loaden vehicle respecting the wheel loading of the outer rail in
curves due to the height of the centre of gravity (see Tables 1 to 3).
 Extensions of acceptance require compliance to a newly defined safety factor of the track loading
parameters λλλλ'.
5.2 Type of on-track test and measuring method
For the acceptance of a new freight vehicle with 112,5 kN < Q ≤125 kN and operational parameters
0
according to Annex A the complete on-track test combined with the normal measuring method is required; the
simplified method is not applicable.
For the extension of an acceptance due to changes of design parameters or operation conditions a
dispensation from on-track tests or a partial on-track test with the normal or a simplified measuring method
can be applied depending on the test results of the accepted vehicle and on the range of changes of relevant
parameters.

NOTE The latter case is possible only if the reference vehicle has already been accepted according to the normal
measuring method. Otherwise a new acceptance is necessary.
The extension procedure referred to here is applicable only if cd ≤ cd .
adm adm, acceptance
If cd > cd , the full procedure and the normal measuring method shall be applied.
adm adm,acceptance
NOTE Tests for wheel loads > 112,5 kN do not cover wheel loads ≤ 112,5 kN due to the different operational
parameters V and cd according to Annex A and EN 14363:2005, Annex G.
In this standard a new parameter χχχχ represents a theoretical estimation of Q depending on the height of
qst
centre of gravity and the permissible cant deficiency.
5.2.1 Choice of on-track test type
The fundamental conditions for freight wagons with 112,5 kN < Q ≤125 kN and operational parameters
0
according to Annex A are the same as in EN 14363 with the following differences:
 a partial on-track test or a dispensation from on-track tests for the extension of an accept
