This procedure describes how to change the transport level for a given region, for a game underway. Here we will manipulate the HOST file.
Open the HST file of your game.
Seek the text {GlobalRegionData}. You are then placed at the start of the data describing regions.
Seek the UID of the region you want to edit, the UID of each region is in the tooltip when you mouse over them.
In patch 1.04, the rail have been removed in regions:
464 - Boone, WV
465 - Kanawha, WV
471 - Mercer, WV
472 - Crawford, WV
474 - Greenbrier, WV
553 - Wayne, KY
554 - Pulaski, KY
566 - Overton, TN
567 - Fentress, TN
568 - Scott, TN
587 - Smith, TN
588 - Cannon, TN
589 - Putnam, TN
So seek first 464 here.
Then in the record, change the value of
TransportLvl=
to something else. The legit values are:
0: nothing
1: track
2: road
3: railroad
4: double railroad (not used in AACW)
131: destroyed railroad
132: destroyed double railroad
Once done, save the file. This will apply when the turn is hosted.
