SIST EN 14363:2016/oprA1:2017

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, 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.
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 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.
The 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.
2)   Infrastructure
In the acceptance process the range of curve radii is (...)

Overview

SIST EN 14363:2016/oprA1:2017 is a European Standard that specifies the testing and simulation criteria for assessing the running characteristics of railway vehicles on the European standard gauge track network (1,435 mm nominal gauge). Published by the European Committee for Standardization (CEN), this standard is essential for ensuring railway vehicle safety, reliability, and compatibility across varying infrastructure conditions.

The standard focuses on both dynamic running behaviour and stationary tests as part of the acceptance procedures for new railway vehicles, modifications to existing vehicles, or changes in vehicle operating conditions. It also offers guidelines for validating simulation models and defining operating parameters for use beyond the established reference conditions.

Key Topics

• Assessment Scope: Applicable to all railway vehicles designed for standard gauge, including freight vehicles with wheelset forces up to 250 kN.
• Test Conditions: Defines target test conditions based on curve radii, speed, and cant deficiency to evaluate vehicle performance against acceptance criteria.
• Vehicle Categories:
  • Newly developed railway vehicles
  • Vehicles with significant design modifications
  • Vehicles with changed operating conditions
• Running Characteristics: Covers both running behaviour under dynamic conditions and stationary measurements for comprehensive assessment.
• Testing Flexibility: Allows assessment under limited test conditions or zones, with appropriate restrictions on vehicle approval.
• Safety Margins: Incorporates unquantifiable safety margins within statistical evaluations, supporting operation even under infrastructure conditions more severe than the test parameters.
• Operating Rules: While operating rules such as cant deficiency restrictions are defined nationally, the standard provides a framework for evaluating compatibility and safety across national boundaries.
• Simulation Validation: Establishes parameters to validate vehicle-infrastructure interaction models, useful in simulation-based design and approval processes.

Applications

• Vehicle Acceptance: SIST EN 14363:2016/oprA1:2017 is the reference benchmark for formal acceptance testing of railway rolling stock within Europe, ensuring interoperability and safe operation.
• Design Modifications: Railway vehicle manufacturers utilize the standard to verify that design changes comply with safety and performance requirements before deployment.
• Operational Adaptation: Railway operators apply findings and methodologies from the standard to adapt vehicle operation parameters in response to infrastructure changes or specific route conditions.
• Simulation and Modelling: Institutions and companies involved in railway simulation rely on this standard to benchmark the realism and validity of their dynamic vehicle models.
• Approval Restrictions: Testing under reduced speeds or cant deficiencies can inform conditional approvals, aiding gradual introduction of new vehicle types.
• Safety Rule Development: Helps regulators and operators define safe operating rules for railway vehicles when infrastructure conditions exceed standard target parameters.

Related Standards

• EN 15686 – Railway applications focusing on infrastructure maintenance and condition monitoring.
• EN 50126 / EN 50128 / EN 50129 – Standards covering railway safety, reliability, and software assurance related to control and signaling systems.
• UIC Leaflets – Various documents by the International Union of Railways that complement EN standards on vehicle dynamics and infrastructure interaction.
• TSI (Technical Specifications for Interoperability) – European regulations governing interoperability of the railway system, often referencing EN 14363 for vehicle running characteristics.

Summary

SIST EN 14363:2016/oprA1:2017 is a fundamental standard that enhances railway safety, interoperability, and operational effectiveness by rigorously defining the testing and simulation framework for running behaviour of standard gauge railway vehicles. Its comprehensive approach encompasses acceptance processes, safety verifications, and simulation validations, making it an indispensable reference for railway manufacturers, operators, infrastructure managers, and regulatory bodies in Europe and beyond.
