Compared to MSTS/ORTS there's so few that have been done it seems:
Mojave Subdivision
Cajon Subdivision (a partial one that represents the main climb, plus an incomplete one on socaltrains, part of the mainlines connecting the Mojave Sub are missing too)
Hi-Line Subdivision (quite dated, but it's quite accurate terrain and trackwork wise)
Roseville Subdivision (one that's no longer available it seems)
Glidden Subdivision (a HORRIBLE one that was put on the DLS in 2015. I still remember it's thread)
Raton Subdivision (TS2 mobile exclusive)
Crawford Subdivision
Powder River Subdivision
Kearney Subdivision (an inaccurate one with ridiciulously sharp curves in some points of the yard, that is Fall Harvest Nebraska)
Keystone Subdivision
Cumberland Subdivision
Mountain Subdivision (CSXT)
Mountain Subdivision (CPKC)
Lurgan Subdivision
Pittsburgh Subdivision
Clovis Subdivision (no longer available)
Moffat Tunnel Subdivision (West from Denver)
Glenwood Springs Subdivision (West from Denver)
compare it to the ones that haven't been done:
Seligman Subdivision (DEM only)
Needles Subdivision (DEM only)
Kootenai River Subdivision (there's a WIP new version of Marias Pass from HP Trainz that'll have it represented as well)
Chillicothe Subdivision (DEM only)
