This Standard specifies requirements for the design and manufacture of turnouts, switches and crossings, and their components.
This Standard does not cover management of turnouts, switches and crossings during other stages of the asset’s lifecycle such as installation and maintenance.
The objective of this Standard is to provide information and requirements for the design and manufacture of turnouts, switches and crossings, and their components.
Turnout switches and crossings are vital track components that allow and control the safe diversion of rail vehicles from one track to another or to cross other tracks.
This Standard is Part 21 of the AS 1085 (Railway track material) series. It also complements AS 7642 which applies to the management of turnouts, switches and crossings during other stages of the asset’s lifecycle such as installation and maintenance.
This Standard has been revised to include the different plate types applicable to each zone for resilient fastening systems.
