CEN/TC 256/SC 1/WG 46 - Ballastless track

This document specifies the implementation of ballastless track system designs and the criteria for the acceptance of works concerning construction of ballastless track systems. It does not include any criteria for inspecting, maintaining, repairing and replacing ballastless track systems during operation.

This part of FprEN 16432 specifies system and subsystem design and component configuration for ballastless track system.
The system and subsystem design requirements are assigned from the general requirements of FprEN 16432-1:2016. Where applicable, existing subsystem or component requirements from other standards are to be referenced.

This European Standard defines the general requirements concerning the design of ballastless track systems.
It does not include any requirements for inspecting, maintaining, repairing and replacing ballastless track systems during operation.
This European Standard is applicable to all railway applications up to 250 kN axle load.
The requirements of this standard apply to:
-   plain line track, switches and crossings and rail expansion joints;
-   various substructures like embankments and cuttings, tunnels, bridges or similar, with or without floating slabs;
-   transitions between different substructures;
-   transitions between different ballastless track systems;
-   transitions between ballasted and ballastless track systems.
NOTE   Requirements for characterization of the substructures listed above are included in this standard. Design of the substructures is covered by other European Standards, e.g. EN 1992–2, EN 1997–1, etc..

This European Standard defines the general requirements concerning the design and acceptance of ballastless track systems.
It does not include any requirements for inspecting, maintaining, repairing and replacing ballastless track systems during operation.
This European Standard is applicable for high speed and conventional railway applications up to 250 kN axle load. This standard applies to ballastless track systems including:
—   booted systems;
—   embedded rail systems;
—   other fastening systems.
The requirements of this standard apply to ballastless track systems including:
—   plain line track as well as switches and crossings and rail expansion joints;
—   various substructures like embankments and cuttings, tunnels, bridges or similar, with or without floating slabs;
—   transitions between different substructures;
—   transitions between different ballastless track systems;
—   transitions between ballasted and ballastless track systems.
