Playing all routes in 64-bit but there were some routes(Montana and some others)which were not working in 64-bits. Anyone who knows if there have been a fix for it or it will come a fix?
It is a fix it yourself situation. DTG moot as to when they will update. Several others, myself included, had successful installations and they now work in 64 bit. Link to patches: https://www.trainsimcommunity.com/mods/c1-train-sim-classic/c13-patches
Thanks for the link to this patch, rwaday ! It worked for me, also And I see they also have patches for Springfield - New Haven Route and Stevens Pass Route with the same 64-bit loading problems. So will also be applying those. Cheers!
