On Hiatus
Don't worry, I've got you covered (not an S-4, but still a 4-6-0).Northern Pacific S-4 #1364 being restored at the Northern Pacific Railway Museum in Toppenish, Wa.
It would be nice to have one of these in Trainz.

Available on my website along with a 2-8-2 and other Northwestern railroads such as GN and CB&Q.
