AS 7644 Rail Corridor Access

The objective of this Standard is to provide technical requirements to enable a rail infrastructure manager (RIM) to design, supply, install and maintain ballastless track systems. The Standard outlines minimum requirements for ballastless track systems. RIMs may accept alternative independently certified products, materials, construction procedures or testing regimes which meet or exceed these requirements. Responsibility for ensuring the minimum requirements are met remains with the parties undertaking the works.
This Standard is intended to be used by rail authority’s, RIM, projects, and specifiers of ballastless track systems and for reference and development by suppliers and construction contractors.

This Standard provides requirements for the structural strength of infrastructure maintenance rollingstock.  The main purpose of the requirements is to:

• prescribe the minimum structural integrity level of the vehicle body to ensure safe performance under normal operating conditions and extreme operating conditions;
• minimize risks to train crew and members of the public in the event of collisions or derailments.

This Standard specifies requirements for as-rolled and hardened steel rails made from continuously cast blooms and profiles for asymmetric switch rails and elevated guardrails for railway purposes.
