AS 7509 - Rolling Stock - Dynamic Behaviour

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 document describes requirements for the structural strength of bogie structures and attached equipment.

The main purpose of the requirements is:

1. to maintain the structural integrity of bogie structures and attached equipment under normal operation; and
2. to minimize risks to passengers, personnel, train crew and members of the general public in the event of collisions or derailments.

The content of this Standard is intended to assist with the compliance assessment process detailed in AS 7501.

The purpose of this Standard is to set out the requirements for ensuring that the track structure is safe and fit for purpose.
