(Main)Railway applications - Testing and Simulation for the acceptance of running characteristics of railway vehicles - Running Behaviour and stationary tests
Railway applications - Testing and Simulation for the acceptance of running characteristics of railway vehicles - Running Behaviour and stationary tests
This European Standard defines the process for assessment of the running characteristics of railway vehicles for the European network of standard gauge tracks (nominally 1 435 mm).
In addition to the assessment of the running characteristics of vehicles for acceptance processes, this standard also defines quantities and dependencies that are not directly used for acceptance purposes. This information is for example intended for the validation of simulation models. It can also be used to define operating conditions outside the reference conditions to be used for the approval.
The assessment of running characteristics applies to vehicles which:
- are newly developed;
- have had relevant design modifications; or
- have changes in their operating conditions.
The assessment process is based on specified target test conditions (see 3.1) given in this document.
Experience over many years has demonstrated that vehicles complying with this standard can be operated safely on infrastructure with conditions more severe than the target test conditions, if the current general operating rules are applied. As an example it is generally current practice to restrict cant deficiency in curves below a certain radius. It may be necessary to adapt these operating rules, if a deterioration of the infrastructure conditions is observed. These operating rules are defined on a national basis. The procedure to evaluate these operating rules is out of the scope of this standard.
NOTE 1 There are margins included in the specified limit values and the statistical evaluation. They cannot be quantified, but they explain why vehicles can also be operated at full speed and cant deficiency in many cases outside of the target test conditions.
This standard also enables the demonstration of compliance against the target test conditions for the case that their combination is not achievable during tests. It is also possible to carry out the assessment of a vehicle for limited test conditions such as test zones 1 and 2 or reduced speed or reduced cant deficiency. In this case the approval of the vehicle shall be restricted accordingly.
NOTE 2 National regulations sometimes allow the increase or decrease of the values for speed, curve radius and cant deficiency for local operation based on safety considerations taking into account the local characteristics of the infrastructure (track layout, track structure, track geometrical quality and contact conditions). These local characteristics can be different from those included in the assessment for the vehicle acceptance.
NOTE 3 The methods of this standard can also be applied to gather information about the compatibility between the vehicle and infrastructure with conditions more severe than the target test conditions. The results of such investigations can be used to determine safe operating rules for such infrastructure conditions.
Where testing the vehicle demonstrates that the performance of a vehicle complies with the requirements of this standard when operating at maximum speed and maximum cant deficiency under infrastructure conditions that are more severe than the target test conditions, the obtained results are accepted and there is no need to carry out additional tests to fulfil the requirements defined in this standard.
This standard addresses four aspects:
1) Vehicles
The assessment of the running characteristics applies principally to all railway vehicles. The document contains acceptance criteria for all types of vehicles with nominal static vertical wheelset forces up to 225 kN (of the highest loaded wheelset of the vehicle in the assessed load configuration specified in 5.3.2). In addition for freight vehicles with nominal static vertical wheelset forces up to 250 kN the acceptance criteria are defined. The acceptance criteria given in this document apply to vehicles designed to operate on standard gauge tracks.

Železniške naprave - Preskušanje in simuliranje voznih karakteristik pri prevzemu železniških vozil - Preskušanje obnašanja med vožnjo in mirovanjem
Ta evropski standard določa postopek za ocenjevanje voznih karakteristik železniških vozil za evropsko omrežje standardnih profilnih tirnic (nominalno 1435 mm).
Poleg ocenjevanja voznih karakteristik vozil za prevzemne postopke standard določa tudi količine in odvisnosti, ki niso neposredno uporabljene za prevzemne namene. Te informacije so na primer namenjene za ovrednotenje simulacijskih modelov. Uporabljajo se lahko tudi za določanje obratovalnih pogojev zunaj referenčnih pogojev, ki bodo uporabljeni za odobritev.
Ocenjevanje voznih karakteristik se uporablja za:
– novo razvita vozila;
– vozila z bistveno spremenjeno zasnovo; ali
– vozila s spremenjenimi obratovalnimi pogoji.
Ocenjevalni postopek temelji na določenih ciljnih preskusnih pogojih (glej 3.1), podanih v tem dokumentu.
Večletne izkušnje so pokazale, da lahko vozila, ki so skladna s tem standardom, varno obratujejo na infrastrukturi v pogojih, ki so zahtevnejši od ciljnih pogojev, če so upoštevana veljavna splošna pravila glede obratovanja. Primer: v splošnem je trenutna praksa omejevanje primanjkljaja nadvišanja v krivinah, ki ne dosegajo določenega polmera. V primeru poslabšanja infrastrukturnih pogojev je morda treba prilagoditi pravila glede obratovanja. Ta pravila so določena na nacionalni ravni. Postopek za vrednotenje teh pravil ni zajet v tem standardu.
OPOMBA 1: V določenih mejnih vrednostih so vključene razlike in statistično vrednotenje. Ni jih mogoče kvantificirati, vendar pojasnjujejo, zakaj je vozila mogoče upravljati tudi pri polni hitrosti in primanjkljaju nadvišanja v mnogih primerih izven ciljnih preskusnih pogojev.
Standard prav tako omogoča prikaz skladnosti glede na ciljne preskusne pogoje v primeru, da takšne kombinacije med preskušanjem ni mogoče doseči. Vrednotenje vozila je mogoče opraviti tudi za omejene preskusne pogoje, kot sta preskusni coni 1 in 2 ali zmanjšana hitrost ali zmanjšan primanjkljaj nadvišanja. V tem primeru je treba ustrezno omejiti odobritev vozil.
OPOMBA 2: Nacionalni predpisi včasih dovoljujejo povečanje ali zmanjšanje vrednosti za hitrost, polmer krivine in primanjkljaj nadvišanja za lokalno obratovanje na podlagi varnostnih napotkov ter ob upoštevanju lokalnih karakteristik infrastrukture (razporeditev tirov, struktura tirov, geometrijska kakovost tirov in kontaktni pogoji). Te lokalne karakteristike se lahko razlikujejo od tistih, ki so vključene v ocenjevanje za prevzem vozila.
OPOMBA 3: Metode iz tega standarda je mogoče uporabiti tudi za zbiranje informacij o združljivosti vozila in infrastrukture pri pogojih, ki so zahtevnejši od ciljnih pogojev preskušanja. Rezultate takšnih preiskav je mogoče uporabiti za določitev pravil glede varnega obratovanja v takšnih infrastrukturnih pogojih.
Če preskus pokaže, da vozilo ob največji hitrosti in največjem primanjkljaju nadvišanja v infrastrukturnih pogojih, ki so zahtevnejši od ciljnih preskusnih pogojev, obratuje v skladu z zahtevami tega standarda, se pridobljene rezultate sprejme in dodatno preskušanje za izpolnitev zahtev, določenih v tem standardu, ni potrebno.
Ta standard obravnava štiri vidike:
1) Vozila
Ocenjevanje voznih karakteristik se v glavnem uporablja za vsa železniška vozila. Dokument vsebuje prevzemne kriterije za vse vrste vozil z nazivno statično vertikalno silo kolesne dvojice do 225 kN (najbolj obremenjene kolesne dvojice vozila v ocenjeni konfiguraciji obremenitve, kot je določeno v točki 5.3.2). Prav tako so določeni prevzemni kriteriji za tovorna vozila z nazivno statično vertikalno silo kolesne dvojice do 250 kN. Prevzemni kriteriji v tem dokumentu veljajo za vozila, ki obratujejo na standardnih profilnih tirnicah.

It is not necessary to require further assessment of vehicles which have been already assessed under the
conditions of previous standards in this field. Test results achieved under the conditions of the previous
standards remain valid and can be used for the extension of acceptance of a vehicle or vehicle design
according to this standard.
Prior to the first issue of this standard, national procedures were applied for vehicle acceptance, for
example in Germany or UK. The underlying principles that were applied in these earlier standards are
also incorporated in this standard. The fundamentals have not been changed but the formulation of the
requirements has been made consistent. Therefore it is considered that also vehicles that were previously
approved utilizing these earlier requirements have an equal status compared to vehicles that are
approved according to this standard. This applies to the infrastructure and operating conditions that
were considered in the earlier approval. This includes also a use as reference vehicle for extension of
acceptance.
Any feedback and questions on this document should be directed to the users’ national standards body.

Introduction
Acceptable running characteristics of a railway vehicle (hereafter called vehicle) are essential for a safe
and economic operation of a railway system. They are related to:
— the vehicle,
— the operating conditions,
— the characteristics of the infrastructure (track layout design and track quality) and
— the contact conditions of the wheel/rail interface.
The objective is to quantify the vehicle's performance under known representative conditions of
operation and infrastructure.
This standard describes methods to assess the vehicle performance in the following areas:
— safety against derailment on twisted track (see 6.1);
— running safety under longitudinal compressive forces in s-shaped curves (see 6.2);
— evaluation of the torsional coefficient (see 6.3);
— determination of displacement characteristics (see 6.4);
— loading of the diverging branch of a switch (see 6.5);
— running safety in curved crossings (see 6.6);
— running safety, track loading and ride characteristics (see Clause 7).
The vehicle performance is assessed in two stages. Usually in the first stage the basic characteristics and
low speed behaviour are investigated before first runs on the line under controlled operating conditions.
In the second stage the running behaviour is assessed. The assessment of a vehicle according to the
elements listed above can be performed either by physical testing, numerical simulation, calculation or
comparison with a known solution (dispensation). Details about the requirements relating to the choice
of the appropriate assessment method are given in this document.
The operational envelope (speed and cant deficiency) that the vehicle has been assessed for needs to be
documented.
The establishment of this document was based on existing rules, practices and procedures. The following
principles were applied:
— the railway system requires comprehensive technical rules in order to ensure an acceptable
interaction of vehicle and track;
— the performance of new railway vehicles has to be evaluated and assessed before putting them into
service;
— it is of particular importance that the existing level of safety and reliability is not compromised even
when changes in design or operating conditions are demanded, e.g. by the introduction of higher
speeds, higher vertical wheel forces, modification of the suspension, etc.
— it is possible to demonstrate compliance with the requirements of this standard by comparison of
relevant parameters or by simulation if changes are made to the design or to the operating
conditions;
— as the combination of all the target test conditions described is not always achievable, the compliance
against the missing target test conditions can be demonstrated by other means.
EN 14363:2016+A1:2018+A2:2022 (E)
Requirements on running safety under longitudinal compressive forces in S-shaped curves of certain
vehicles are given in EN 15839, while EN 16235 specifies a method to get dispensation from on-track
testing for !vehicles equipped with established or standardised running gear", if certain conditions
are fulfilled.
The informative Annexes A, B, C, D, E, F; Q, S, T and U contain requirements that have to be fulfilled when
the annex is applied.

1 Scope
This European Standard defines the process for assessment of the running characteristics of railway
vehicles for the European network of standard gauge tracks (nominally 1 435 mm).
In addition to the assessment of the running characteristics of vehicles for acceptance processes, this
standard also defines quantities and dependencies that are not directly used for acceptance purposes.
This information is for example intended for the validation of simulation models. It can also be used to
define operating conditions outside the reference conditions to be used for the approval.
The assessment of running characteristics applies to vehicles which:
— are newly developed;
— have had relevant design modifications; or
— have changes in their operating conditions.
The assessment pr
