Re: Australia's most unreliable tramway dies yet again.
From: Tony Galloway

If the phone rings once and drops off that means their phone queueing system is overloaded - it happens with Centrelink all the time.

When I was working in signal construction we put in a lot of duplicated SCADA links to avoid this sort of problem. The A and B lines followed different routes so if one was knocked out by physical damage the other wasn’t damaged along with it. Why GCLR didn’t install this is a question of design competence - building in redundancy is a no-brainer.
