Not sure if this helps you, but I have yet to receive mine and ordered in September 2012. Finally got a confirmation of my order in December 2012. I provided my updated details in March this year at the same time as ordering the PL carriages (which I got last Thursday).
I rang Austrains on 5 August, and I was told my PL cars had been sent on Monday and I did get them 12 August. At the time I was told my G Class and NQR Candy 81 Class details were verified and he would need to hit the Bank Account for them the next Thursday (14 August). He said by then he should be finished posting all the verified pre-ordered PL's. He is very keen to sell at the two Exhibitions next weekend, after delivering all pre-orders. My loco order has not arrived as of yesterdays mail.
Don't forget if you attend Caulfield, Austrains reminded me, their is secret model being released. It is a VR model and the only clue is they are no longer in service but 80's and earlier modellers are going to love them. They ran main and branch lines and were very useful things indeed. When I suggested a ZL he said, No, not a ZL. Wish somebody would do ZL's
