 N SN EN 15839

Annotation

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);
