Hello upbb4884, you must let the rest of the WORLD catch up with your questions, we are not all on the same time difference, and some of us do have a day job as well....:hehe:
From memory, 2 snow-themed North American routes spring straight to mind, both on the DLS, Regional Passenger Transit 2005 by Euphod, KUID is 7592:1656604 and Albany Northern by NYOW2000, KUID is 57447:100109.
All of these are OK for TRS2004.
There was a Wyoming Coal layout created by John Keenan, a year or so ago, but it is on a 3rd party website, sorry, cannot remember which one it is now, maybe one of your fellow Americans might know where you can look.
Happy trainzing.
