Great initiative, but, really, wouldn't this list be better placed in the Trainz Wiki. Sooner or later this blog post is going to disappear from the radar and so people will never find it, unless they already know it's there. A Wiki entry might be easier to spot for newcomers.

Cheers, Nickie
I will look into that, but from what I've noticed, most users come to the forums/blogs first,rather than the Wiki.

It's always going to be available through other methods, including my tutorial website.

How about adding:
TRS - Trainz Railroad/Railway Simulator, a number after indicates version
TS#- Trainz Simulator, a number after indicates version
UTC - Ultimate Trainz Collection
Pre-SP3 - 1st version of Trainz
SP# - Service Pack, a number after indicates version
TC# - Train Classics, a number after indicates version
OP - Opening Post (general forum abbreviation, not limited to TRS)
RW - Railworks (Trainz Competitor)
RS - Rail Simulator (Trainz Competitor)
MSTS - Microsoft Train Simulator (Trainz Competitor)

Hi Peter,

I have now added the abbreviations above, with small modifications to keep within character limits.

I've also corrected an error with the Ultimate Trainz Collection entry.
