SRA Detonators

The following item posted by Eikkert got no responses on the Australian
Transport Discussion Board. I think it is more likely to get a response
here.

'Why aren't detonators ever used anymore? I never hear them. I know there
was a big furore about them a few years back but from what I've seen SRA use
ppl with flags and whistles now. And from experience they truly aren't
effective if a train is going the other way at the same time. A crew nearly
got hit at Hurstville station because they didn't hear the whistle as
another train was standing on the platform beside where they were working. A
detonator would have worked well there. They must save more lives than they
take.'
