Machine Avoidance and the RMAD
At KiwiRail, we are researching ways in which to work nearer our overhead wires on our traction systems to increase productivity in the maintenance space. This is for work under or near the overhead (e.g. using diggers, track machinery etc.) and not work on the overhead – for that we require a full isolation.
We use ECP34 to define our MADs and RMADs, currently we can work up to 2m from the live overhead for plant and people using the RMAD with our current set of controls. We are investigating using new technology such as machine avoidance and remote switching to reduce this RMAD further to work under an isolated but not earthed line. This is all with the aim of increasing our maintenance access windows.
Whilst we often look overseas for similar practices used in other rail networks, I am seeking any NZ distribution companies that may be exploring similar options using this technology (if it is even applicable), or those who already use it. Would be great to hear from anyone.

Hi Hugh.
Appreciate you posting on the forums.
Im assuming youre referencing table 6 of ECP34?I would suggest as those numbers are legislated that these are the numbers that you should work to.
If youre looking at technology that can assist you with identifying when youre at those limits then Glen (Cookie) Cook is a great resource to tap in to. Glen.Cook@energyq.com.au
Happy to chat if you want to reach out.
