The route editor was announced for TSW2 content only.Many people were exited that TSW2 would have editor for preserved content but it was announced that it wouldn't.We were promised editor but we never got it for TSW1.I hope there is a way to make TSW1 content with the route editor.This isn't an anti-DTG post this is just my opinion for TSW2
From what I gathered any DLC or routes from TSW1 will not updated further after TSW2 is out unless it's to update a major bug. Doubt they'd be working on TSW1 routes anymore and focusing in TSW2. Bit of a shame It is what it is
