It didn't look like that Facebook page has been updated in over a year unless I missed something.
The site has been down for close to a month now I guess. The last I heard was it was going under for a site rebuild and was having issues with spam. That was several weeks ago though so any news would be nice. I had to do a complete re installation of Trainz after a botched SP1 installation and lost all of my USLW stuff and I'm sorely missing it, especially the offset hoppers, GP30s, and some of the scenery dependencies for the Reading and Northern route.
