I dug this up, maybe its irrelevant but it does give good detail as to dimensions of flanges etc if you are having derailments it may help;

Thanks Trev.

Some small but interesting differences between your dimensions & the U.S.' NMRA.

Your tightening of track gauge min/max at V and K crossings (not always shown in other track spec tables) is a good idea in my opinion. I haven't built much track but that is exactly what I do; I'm sure it improves tracking.

A page to use to compare the Australian standards to both normal NMRA HO, and Proto:87 HO, http://www.proto87.org/d/?q=node/3
