Yes I'm still around, but only have limited time for Trainz at the moment.
We have had this conversation before though. I do not want to back date my assets to TRS2004 and have them hosted externally. Even if I was interested, I've never had TRS2004 and I have no way of knowing if they will work correctly. You would be far better referencing a built-in espec from that time. There was a big change in especs from TC3/TS2009 which is where I came on board, content creation wise. This especially applies to multiple unit stock - I suggest you try using the VR EMU stock which I think dates from back then.
