Go to Morandoo and Port Waratah. If you are at Morandoo by about 1300 you can usually catch a shot of the Brisbane - Wollongong steel train (*BW4) arriving into the yard (usually between 1300-1400). Good places to photgraph it are:
Scholey Street bridge - go down Mayfield back streets
Industrial Drive bridge - GOOD SPOT - Either on top of the bridge or under it with a stepladder or something to look over the security fencing.
The same train will shunt and attach/detach traffic and then depart between 1530 - 1630 (tabled @ 1630).
You can also go to Carrington and view shunting from the overhead footbridge which takes you to the harbour side.
Have fun
Cheers,
Steamy
