Hi Jim,

I'm Mike the groups owner. Because the locomotives are so long and
noisy, crews had troubles hearing the detonators going off to warn
them of workers on the track ahead. Here in New South Wales, to warn
workers and train crews that there was people on the track, a flagman
would set 2 detonators on the track to warn both. 3 "dets" on the
track means danger and halts any train from proceeding further into
danger. If you look at pictures of the 60 class, the sound tubes lead
down to the leading wheel on the right side on both ends. I hope that
this helps?

Mike P
