I was wondering if anybody knows where I could find some Melbourne Trams, specifically D1 or D2 Combino, C1 Citadis or E Class for Trainz Simulator (on a Mac).

I'll really appreciate if there are ones without the generic Trainz tram sound, this seems to be the case with the Combinos on the Download Station. So far after some research, I have only been able to find Combino trams with a generic tram sound (I have seen the ones on Ptram and other similar sites).
