Think that dovetail should add the bellingham sub here in washington. there is some very pretty landscape, their is some mainline freight traffic along with amtrak (including amtrak cascades) and some switching for the local that goes to the anacortes refinery branch. Surely it would be a daunting task but would absolutely amazing to see in TSW2.
BNSF won‘t grant a license for worldwide use. Only US players could play a licensed BNSF route/loco while everyone else would have to get unbranded versions. DTG have made it clear that they will not develop content for TSW without a license which means that no BNSF route/loco will come to TSW until BNSF has a change of heart.
