0 in the screenshots are for showing the texture and how it looks in game. It is not for to show a proper Runway. "0" it is for using other single digit numbers if you prefer to use them (US and EU may be different).

luke12805 is right, there is no runway 0. the 0 is only used in combination with another digit.

@luke12805 it doesnt work like that in this addon. If your runway is 10, you download this and 1. Then place both in game :)

There is no 0 runway marking. It's 36

U need to use anarchy addon to use them

How do you add numbers to the runway (i have the runway numbers installed it just wont let me put them on)

Would you upload an all in one pack version of the letters and numbers?

These markings have no bussines with that mod. They are just cosmetic. Created by creator for in game airports and custom airport roads. So i dont think it is nothing about these markings.

There is a mod that makes it possible to choose if a transport building like an airport is vanilla or for local traffic only while pressing ALT when placing it.

Really dont understand what you mean. When i last played 2-3 weeks ago they were working normally. Cannot check "local traffic" atm. Could you please be more specific?

Why all these markings say they only allow local traffic when placed without pressing ALT ?
