(Amendment)

Railway applications - Testing for the acceptance of running characteristics of railway vehicles - Freight wagons - Testing of running safety under longitudinal compressive forces

Railway applications - Testing for the acceptance of running characteristics of railway vehicles - Freight wagons - Testing of running safety under longitudinal compressive forces

This European Standard defines the acceptance process to be followed by vehicles that are operated in trains capable of generating high longitudinal forces and that are susceptible, as a result of their design, to derailment as a result of being subjected to these forces.
This European Standard applies to the following types of freight wagons equipped with standard ends as defined in this EN:
— single wagons;
— permanently coupled units with side buffers and screw couplers between the vehicles;
— permanently coupled units with diagonal buffers with screw couplers between the vehicles;
— articulated units with three 2-axle bogies;
— low-floor wagons with eight or more axles (e.g. rolling road wagon 1).
The following vehicles are not currently in the scope of this European Standard:
— wagons that are not subjected to extensive longitudinal compressive forces due to their operational environment (as train composition, braking regime, track layout);
— wagons with automatic couplers 2);
— wagons with 3-axle bogies 3);
— permanently coupled units with a bar coupler between the vehicles 4);
— articulated wagons with more than three 2-axle bogies.
Acceptance criteria and test conditions as well as conditions for the dispensation from tests are defined in this European Standard.
This document applies principally to wagons which operate without restriction on standard gauge tracks in Europe (1 435 mm).
NOTE The influence on railway systems using other gauges is not sufficiently understood to extend the scope of this document to gauges other than standard.

Overview

EN 15839:2012/FprA1 - Railway applications: Testing for the acceptance of running characteristics of railway vehicles - Freight wagons - Testing of running safety under longitudinal compressive forces (CEN) defines the acceptance process for freight wagons that may be susceptible to derailment when subjected to high longitudinal compressive forces. This draft amendment to EN 15839:2012 clarifies test configurations and updates scope-related references (Annex ZA). The standard applies principally to wagons operating on standard gauge (1 435 mm) tracks in Europe.

Key topics and requirements

  • Acceptance process: Specifies the required procedure to accept wagons whose design and operational environment expose them to significant longitudinal compressive forces.
  • Test conditions and acceptance criteria: Defines the conditions under which running-safety tests must be performed and the criteria used to judge acceptability. The standard also covers conditions for dispensation from tests when appropriate.
  • Wagon types in scope: Applies to freight wagons equipped with standard ends, including:
    • single wagons
    • permanently coupled units with side buffers and screw couplers
    • permanently coupled units with diagonal buffers and screw couplers
    • articulated units with three 2-axle bogies
    • low‑floor wagons with eight or more axles (e.g., rolling road wagons)
  • Wagon types excluded: Explicitly excludes wagons that are not subject to extensive longitudinal compressive forces and several configurations such as:
    • wagons with automatic couplers
    • wagons with 3‑axle bogies
    • permanently coupled units with a bar coupler between vehicles
    • articulated wagons with more than three 2‑axle bogies
  • Amendment notes: The FprA1 draft modifies figure keys for test train configuration and removes Annex ZA following changes in the TSI Freight Wagons reference.

Applications

  • Acceptance testing of freight wagons before entry into service where high longitudinal forces may occur (e.g., specific train compositions, braking regimes or track layouts).
  • Risk mitigation against derailment due to compressive forces during operation.
  • Defining test protocols and pass/fail criteria for manufacturing quality control and regulatory approval.

Who uses this standard

  • Wagon manufacturers and designers responsible for dynamic stability
  • Railway operators and fleet owners performing acceptance testing
  • Certification bodies and national safety authorities carrying out homologation
  • Test laboratories and rolling stock maintenance organizations

The purpose of this document is to provide methods for quantifying the ride comfort of a passenger in a rail vehicle in response to the track sections it is operated over.
The methods aim to quantify the effects of vehicle body motions on ride comfort and to make the assessment of passenger comfort predictable, repeatable, objective and meaningful.
The methods and comfort scales are validated for people of good health.
This document applies to passengers in rail vehicles operating on heavy rail networks.
This document applies to measurements of motions. It also applies to simulated motions. Guidance is provided on:
-   which method described within the document should be used for different scenarios;
-   typical values for different comfort levels;
-   the application of simulation.
This document excludes health and safety issues, non-passenger carrying vehicles, vehicle homologation and safety, limit values, motion sickness, discomfort caused by accelerating and braking, design guidelines and measurement technology.

Railway applications - Testing and simulation for the acceptance of running characteristics of railway vehicles - Running safety under longitudinal compressive force
SIST EN 15839:2024

This document defines the assessment of endurable longitudinal compressive force (LCF) of a vehicle. The endurable longitudinal compressive force is a parameter depending on the vehicle design. It is used to estimate the risk of derailment of a vehicle as a result of being subjected to longitudinal compressive force, under operating conditions.
NOTE 1   As operating conditions can vary in several aspects (infrastructure, train configurations etc.), this document defines uniform assessments of endurable longitudinal compressive force per vehicle in specific operating conditions. The main assessment of endurable longitudinal compressive force for conventional trains is derived from UIC 530-2:2011, which is based on practical tests performed in ERRI-B12. Assessments of endurable longitudinal compressive force for high-capacity trains in this document are required by the methodology of IRS 40421. IRS 40421 assesses operational train parameters.
This document applies to the following types of vehicles:
-   single wagons;
-   permanently coupled units with standard ends between the vehicles;
-   permanently coupled units with diagonal buffers and screw couplers between the vehicles;
-   permanently coupled units with a bar coupler between the vehicles;
-   articulated units with 2-axle bogies;
-   wagons with 3-axle bogies;
-   low-floor wagons with eight or more axles (e.g. rolling road wagon);
-   vehicles with centre couplers;
-   railbound construction and maintenance machines as defined in EN 14033-1:2017.
NOTE 2   This document defines the acceptance process to be followed by vehicles that are operated in a way that high longitudinal compressive force occur in the trains due to their operational environment (e.g. train composition, brake mode, track layout).
The following vehicles are not in the scope of this document:
-   locomotives and passenger rolling stocks;
-   vehicles that are only operated in passenger trains.
NOTE 3   Locomotives, passenger rolling stocks and vehicles operated in passenger trains only are not in the scope of this document as they either are subject to low longitudinal compressive force in operation or have sufficient endurable longitudinal compressive force due to their axle load.
Acceptance criteria and test conditions as well as conditions for simulation are defined in this document. Conditions for dispensation of the assessment of the endurable longitudinal compressive force are also defined in this document.
This document applies principally to vehicles which operate without restrictions on tracks with a gauge of 1 435 mm in Europe.
NOTE 4   The influence on railway systems using other gauges is not sufficiently understood to extend the scope of this document to gauges other than 1 435 mm.
NOTE 5   For wagons with centre couplers, a need for assessment of derailment risk due to Longitudinal Forces on other gauges (1 524 mm, 1 600 mm, 1 668 mm) has been expressed. The influence on railway systems using other gauges is not sufficiently understood. This document only introduces some notions to assess it independently from the gauge.
