ABDW euipment has another reservior on each vehicle. This provides a
quick release and a local emergency application feature. Propogation
times are much less than with the "Australianised" equipment. 1500
metres is about the practical limit (except on flattish terrain) for
the Oz stuff. Longer trains will require some new equipment. I hope
that ARA make sure that there is a new Australian Standard before
companies start going their own way.
