Re: SRA Detonators

["Robert Parnell" <rparnell@netspace.net.au>]

Detonators are used as an indication to drivers rather than as an audible
warning for workers on the running line. The protection of a work site these
days is slightly different to that in the past - a track possession is
preferred, rather than to keep trains running and slowing them down. The use
of dets is also an issue with noise pollution, so their use is avoided as
far as possible. Dets are still used, they just don't go off as much.
