This document 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, the 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 and applies to reference conditions (see 3.2) of infrastructure also defined herein in combination with the maximum operating conditions (speed and cant deficiency) defined for the vehicle. The standard also enables the demonstration of compliance against the target test conditions for the case that their combination is not achievable during tests.
NOTE 1 National regulations may allow the increase or decrease of the values for speed 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 characteristics can be different from those included in the assessment for the vehicle acceptance.
NOTE 2 For infrastructure conditions more severe than the reference conditions safe operation of the vehicle is achieved by general operating rules. These operating rules are defined on national basis. The procedure to evaluate these operating rules is out of the scope of this standard.
NOTE 3 It is generally current practice to restrict cant deficiency in curves below a certain radius.
NOTE 4 It is assumed that vehicles complying with this standard can be operated safely on infrastructure with conditions more severe than the reference conditions, if the current general operating rules are applied. It may be necessary to adapt these operating rules, if a deterioration of the infrastructure conditions is observed.
NOTE 5 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 reference 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 reference conditions it is recommended that the results of such investigations (test and proven operating conditions) are documented to avoid unnecessary testing in several countries.
This standard addresses four aspects:
Vehicles
The assessment of the running characteristics applies principally to all railway vehicles. The document contains acceptance criteria for all types of vehicles with axle loads up to 225 kN. In addition for freight vehicles with axle loads 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.
Infrastructure
In the acceptance process the range of curve radii is defined, in which the vehicle is assessed. A vehicle accepted according to the requirements of the standard is able to be operated on all standard gauge tracks complying with EN 13803-1 and EN 13803-2.
This document also gives guidance about the handling of geometric track quality associated with the assessment.
