G'day Scott....I met a couple from California a few years ago in our local museum...they were visiting our State , Tasmania , as part of a three month trip to Australia and New Zealand...Really nice people and we talked for about half an hour , I'm a pretty good talker ....I'd only just started building my first HO layout after deciding to switch from N Scale and I love the American rail system , diversity , so many options , and due to that a great choice of models...Our systems in Australia , apart from the huge mining unit trains in Western Australia (WA) and Queensland like BHP Billiton , Pilbara Rail , and Rio Tinto are run by state governments , including our own TasRail..So to have the great competition in the private sector rail like yours must lead to competitive trading and better shipping prices...I'm modelling mostly BNSF but also transition period ATSF/BN stuff , run SD40-2s , SD70 ACe s A couple of GE 8-40 CWs , same with GE 9-44 CWs and more recently some nice ES44 ACs...and doing double stack mostly.Just curious...what era are you likely to model?...No matter what you choose , you'll find some genuine experts to help you via this fantastic forum...people who REALLY know their stuff...I've been helped several times already...and may have added a tiny bit back once or twice...By the way , the California couple who weren't rail fans did know of Cajon Pass...I said it like Cage On Pass but was politely corrected to say it more like Cahone Pass...only seen it on You Tube til then...Great to talk to you...Enjoy the forum...Cheers Rod...
