Hi Garry.
There is not many Steel Mill modellers over in West Australia BUT believe it or not there are a couple more in sadly (for me) HO scale. I am a member of the NMRA steel group only joined a few months ago can you get back copies of their journal ?
Your layout and website is impressive very nice and of course your layout is wonderful, there is a HO section at OGR where you can post, I have only one place on the internet where I post about my Railroad and that's here on the OGR forum so if you want to keep informed on what I get up to look here and the structures threads. In O scale you have to scratch build almost everything for a Steel Mill which is not that hard just time consuming as we run the layout every week so I work in between building and operating and of course keeping the layout in good shape. Take care. Roo.
