Yes you can...
We didn't have a forum for requests till the TRS06 forum came along. Or atleast not that I know of.
As on Railpage, there is a Geelong line for TRS04 (Will work in TRS06, although there may be faulty dependencies), although not with DEM based terrain, not prototypical track work, but it is still a nice layout.
I have got a set of diagrams for the V/Locity, but it's not a top priority at the moment.
