So I'm here on this overpass in OSD. But I can't see that track under the bridge in the map on TSW 2&3&4. And this rusty track (near the east-south wye) is missing in the map, too. Why?
Oakville had a problem upon release. The map showed all tracks, but it turned out about half of them were inaccessible. You can sometimes see inaccessible tracks on different routes to illustrate further routes, but here, it caused a lot of problems and upset the community. Therefore, quite hastily, all inaccessible tracks were removed from the map instead of opening up the missing locations.
I remember someone posted a map with those tracks shown. Shot taken on TSW2 Rush Hour DLC, but forgot which thread/post.
