Call for Development Group Members – AS 7481 Train braking rates

The Rail Industry Safety and Standards Board (RISSB) is seeking nominations from people to join a Development Group to create a new Australian Standard® – AS 7481 Train braking rates. 

The Standard will:
• Provide a common method for calculating, field testing and determining the braking rates of trains under ideal and non-ideal conditions.
• Document requirements for managing slip-slide events for fixed-block and moving-block signalling systems, to ensure safe separation of trains and safe arrivals at terminating stations.
• Identify the need for harmonious braking rates, so that future purchases of trains can be interoperable with infrastructure already equipped with ATP (or similar) technology, by ensuring new rolling stock has appropriate braking performance.
• Document current practice or braking performance of current train fleet. This could be beneficial to other railways who may be more or less conservative in their signalling systems design based on their braking performance of trains.
• Cover braking enhancement systems and adhesions enhancement systems.
• Provide alternative treatments where braking performance is poor or below standard due to adhesion conditions, to allow ATP technologies to integrate with train braking systems.

How to contribute
Stakeholders and interested parties are invited to submit nominations for subject matter experts to join this Development Group to contribute to the overall depth and quality of the Standard.

Development Group membership is voluntary and requires the support of your organisation to attend and contribute.

There will be 4 meetings over the development period (2 x face-to-face & 2 x teleconferences) over the next 12 or so months.

All nominations and enquiries are to be submitted to iroutcliffe@rissb.com.au

As part of your nomination, can you please provide a brief detailing your contact details, your interest in this development (materially affected party, subject matter expert, etc.), and any other information which might support your participation.

Your information will assist us in ensuring a balanced representation from all major interest categories in the development of this document.

Closing date for nominations is COB Monday, 30 March 2020
