Railway applications - Testing for the acceptance of running characteristics of railway vehicles - Freight wagons - Conditions for dispensation of freight wagons with defined characteristics from on-track tests according to EN 14363

This document defines the process to determine the conditions under which dispensation from on-track testing according to EN 14363 can be given to freight wagons. In its application this document specifies the means by which dispensation from on-track tests is possible.
This document is subordinate to EN 14363.
The dispensation conditions described in this document apply to all freight wagons and non-powered special vehicles with operating conditions of freight trains, which are operated on the heavy rail network with standard gauge (1 435 mm).
NOTE 1   The various rail-inclinations used in Europe (1:20, 1:40 and 1:30) are covered by the conditions for dispensation.
This document is not limited to any type of freight vehicle; however, freight wagons with defined parameters and equipped with certain running gear types, which have been previously accepted, are considered to have a continuing dispensation from on-track testing. The parameters of these freight wagons and running gear are detailed within this document.
NOTE 2   The test procedures described in this document (and in EN 14363) can be applied also to applications with other track gauges e.g. 1 524 mm or 1 668 mm. The limit values could be different. If established running gear are existing in such restricted networks the related ranges of running gear and vehicle parameters for dispensation from on-track tests might be specified together with the operational parameters (speed, can’t deficiency, maximum axle load) based on previous tests and operating experiences. These limit values and parameters will be specified on national level.
This document only contains requirements for characteristics related to requirements for on-track tests specified in EN 14363.

European foreword

This document (prEN 16235:2022) has been prepared by Technical Committee CEN/TC 256 “Railway

applications”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 16235:2013.

In comparison with the previous edition EN 16235:2013, the following technical modifications have

been made:

— Scope adapted to the terminology given in EN 17343 and extended to non-powered special vehicles

with operating conditions of freight trains;
— normative references updated;

— references to withdrawn EN 15687 replaced by references to EN 14363 in the whole document;

— in Table 12 and Table 15 the parameter “mass of the wagon” was replaced by a requirement for

“axle load” in tare condition;

— modification of the test procedure for a new standardized running gear: requirements for the

length of the tested wagons were deleted and replaced by an application range for the wagons

based on the lengths of the tested wagons (Table 1 deleted);

— clarification that the use of simulations according to EN 14363 can replace physical testing;

— clarification that the minimum and maximum axle load specified for the application range are the

limits for the load conditions for the operation and not necessarily for the design of the wagon;

— Annex ZA deleted.

Introduction

EN 14363 defines the requirements for railway vehicles with respect to running behaviour. The

approval process in accordance with EN 14363, including the dispensation defined in this document, is

illustrated in normative Annex B, Figure B.1 (flow chart).

It is recognized that experience has demonstrated that running gear fitted to wagons that operate safely

can also be fitted to other wagons which are within certain design limits. These other wagons will also

operate safely without the need to undergo on-track testing. This experience is based on the

characteristics of track design, track maintenance and vehicle maintenance in the European network

since 1998. This document defines the process to determine the conditions under which such

dispensation from testing can be given for a vehicle defined by the running gear and its relevant

parameters together with the associated parameter limits of wagon bodies.

Vehicles for the transport of freight on the railway have historically been subject to standardization.

Very early common items like wheels, buffers, draw gear, etc. were developed as standardized

components to fulfil safety requirements, for achieving ease of repair and maintenance for international

traffic and low cost. Freight wagons have a wide range of applications and consequently the parameters

will vary. In the UIC work for the standardization and interchange of freight wagons certain processes

for acceptance with respect to running characteristics evolved and these were formalized in UIC 432

and UIC 572 among others. The principles of this document are similar to the intention of these two

leaflets.

NOTE Vehicles accepted through the UIC process were also accepted for RIV (Regolamento Internazionale

Veicoli) service, i.e. international interchange between the RIV railways. This was replaced by the General

Contract of Use for Wagons (GCU) agreement on 1 July 2006. Following the Directive 2008/57/EC the

Conventional Rail Technical Specification for Interoperability for Freight Wagons (CR TSI WAG) was elaborated,

which contains interoperability requirements for freight wagons.
The following principles apply to the use of this document:

1) the railway system requires comprehensive technical rules in order to ensure an acceptable

interaction of vehicle and track;

2) new railway vehicles are approved (in the UIC 432 the term homologated is used) before being

placed into service in accordance with numerous national and international regulations. In

addition, existing approval is checked when operating conditions are extended. The approval is

based on test results, calculations and/or comparisons with existing vehicles in order to achieve a

safety level according to the recognized standards and regulations;

3) 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.

This document does not prevent the use of the principles laid down applying to other types of rolling

stock.

1 Scope

This document defines the process to determine the conditions under which dispensation from on-track

testing according to EN 14363 can be given to freight wagons. In its application this document specifies

the means by which dispensation from on-track tests is possible.
This document is subordinate to EN 14363.

The dispensation conditions described in this document apply to all freight wagons and non-powered

special vehicles with operating conditions of freight trains, which are operated on the heavy rail

network with standard gauge (1 435 mm).

NOTE 1 The various rail-inclinations used in Europe (1:20, 1:40 and 1:30) are covered by the conditions for

dispensation.

This document is not limited to any type of freight vehicle; however, freight wagons with defined

parameters and equipped with certain running gear types, which have been previously accepted, are

considered to have a continuing dispensation from on-track testing. The parameters of these freight

wagons and running gear are detailed within this document.

NOTE 2 The test procedures described in this document (and in EN 14363) can be applied also to applications

with other track gauges e.g. 1 524 mm or 1 668 mm. The limit values could be different. If established running

gear are existing in such restricted networks the related ranges of running gear and vehicle parameters for

dispensation from on-track tests might be specified together with the operational parameters (speed, can’t

deficiency, maximum axle load) based on previous tests and operating experiences. These limit values and

parameters will be specified on national level.

This document only contains requirements for characteristics related to requirements for on-track tests

specified in EN 14363.

4 Deviations from requirements

If deviating from some points of the requirements of this document for a particular assessment, these

deviations shall be reported and explained. Then the influence on the assessment of the vehicle in terms

of the acceptance criteria shall be evaluated and recorded. The outcome of this study shall be

considered as an integral part of the requirements of this document when applied to the assessment

process of the vehicle.
5 Acceptance process to achieve a standardized running gear status
5.1 General

Standardized running gear according to this document shall be certified. For this purpose on-track tests

according to EN 14363 shall be carried out with two different vehicles. If both vehicles pass the tests

described in 5.2, the running gear shall be certified as standardized running gear in a 'declaration of

conformity' with this document that contains:

— a description of the standardized running gear; the relevant parameters and their proven range as

specified in 5.3 and 5.4;
— the range of applicable parameters of the vehicle body as specified in 5.5;
— the applicable operating conditions.

Vehicles with parameters within the range defined in the 'declaration of conformity' and equipped with

a standardized running gear have dispensation from on-track testing according to EN 14363.

The established running gear defined in Clause 6 of this document shall be regarded as fulfilling the

requirements of this chapter and the parameters specified in Clause 6 shall be regarded as equivalent to

the 'declaration of conformity'.

This procedure applies only to the on-track tests as required in the relevant clauses of EN 14363. It

does not give approval for safety against derailment on twisted track (5.1) and under longitudinal

compressive forces in S-shaped curves (5.2).

5.2 Test requirements
5.2.1 Extent of tests

On-track tests shall be carried out according to the complete procedure specified in EN 14363.

The tests shall be performed for the same intended operating conditions (V and I ) with two

adm adm
wagons with different body parameters:
— one wagon of short running gear distance;
— one wagon of long running gear distance.

To achieve a wide range of accepted running gear distances for two axle wagons, it is recommended to

test one wagon with 2a* ≤ 7 m and one wagon with 2a* ≥ 9 m. For bogie wagons it is recommended to

test one wagon with 2a* ≤ 7 m and one wagon with 2a* ≥ 13 m.

The torsional coefficient of vehicle bodies shall be between 0,5 · 10 kNmm/rad and

8 · 10 kNmm /rad for each tested wagon.

For the purposes of assessment of running behaviour in loaded condition, a typical loading condition

shall be tested.

NOTE 1 It is not necessary to test the worst position of centre of gravity (as it is in most cases impossible to

have a density of the load, filling the whole loading gauge, that would lead to the maximum axle load).

In addition, 2 axle wagons for speeds ≥ 100 km/h shall be tested in loaded condition also in sections of

test zone 2 with clearances given by a gauge ≥ 1 450 mm in combination with wheelsets having

distances between active faces at the minimum operation limit.

If the design parameters and the operation parameters require the application of the normal measuring

method, it is nevertheless acceptable to perform such tests with one of the vehicles based on

measurements of lateral acceleration. In that case, it shall be demonstrated that a relationship exists

between accelerations and the sum of the guiding forces on the vehicle tested according to the normal

measuring method and a related limit value shall be established.

NOTE 2 This requirement is an extension of the application of the simplified measuring method, using

information gathered with vehicle tested according to the normal measuring method.

Physical testing according to EN 14363 can be replaced by simulation if EN 14363 allows for that.

5.2.2 Certification

The compliance of new types of bogies or running gear with the requirements of this document shall be

documented in the 'declaration of conformity' with this document. This declaration shall include:

— an unequivocal and unique name for the running gear;

Following successful testing according to 5.2 the acceptable parameter variation range for a

dispensation from on-track tests for single-axle running gear and bogies is given by the range between

the nominal tested parameters of the running gear and the extended range where specified in Table 1

and Table 2 for single-axle running gear and bogies. All parameters given in these tables are nominal

values. The upper limit of the acceptable range depends on the maximum tested value of the respective

parameter, the lower limit on the minimum tested value.
Successful testing means that on-track t
