QR electric coal trains near Rockhampton[QLD]

["James C" <noemail@emailsux.com>]

I wish to take photos of QR's electric loco haul coal trains while at
Rockhampton. If I stand near the junction (Rockland?) of North Coast line
and line from Emerald near Rockhampton, how often will I see a coal train?
(say during weekdays) and what's the busiest time of the day for this
junction during weekdays?

Cheers
James
