Well done that man! This is in my stock install for testing ideas.
Majormagee, I did not notice that MAW had the lines.
I am trying out things in the vectordatalinings.xml, just added "railroad" as a vector and used stock stone walls and power lines. For some reason I do not see the stone walls although I tried adding them to city landclasses only - my GTX770 was brought to its knees - 17FPS.
Wonder what else would be worth putting along stock vectors?
I could not find a list of what constitutes vectors in the SDK.
At a guess, shipping lanes might be vector data. Maybe mines could be sown around the place? Just riffing here..
