This specification applies to public road level crossings and pedestrian level crossings. It is applicable to the construction of new crossings and the upgrading and maintenance of existing level crossings. This specification does not cover the requirements for passive level crossing protection although some aspects of the active pedestrian crossings will be applicable to both. Passive protection requirements are included in CRN CS 520. This document is to be read in conjunction with CRN Specifications:- - - CRN SD XXX series Signalling Design Principles which defines the operating parameters for level crossings, - CRN SE 038 Manufacture and Assembly of Level Crossing Equipment - CRN SC 021 Construction of Cable Route and Associated Civil Works which defines post foundations, - CRN SC 015 Specification Installation of Trackside Equipment which defines installation requirements for associated works. Level crossings represent a significant safety risk to passengers, train crews, pedestrians and motorists. The design of level crossing and protection equipment utilised, is to be undertaken only after the safety risk and all other factors have been fully assessed and resolved and is to be based on relevant Australian Standards and Codes of Practice and requirements specified in this document. Level crossings are installed to provide a safe track crossing, at grade, for road, pedestrian and stock traffic. Level crossings may also provide access points
