Thank you anyway, I decided to go with pre-built airports. For those of you still wanting to build one that works, here is an excellent youtube to learn how:

Sorry mate, I haven't had this game installed for three years now, and I don't plan to anytime in the forseeable future. Nevertheless, good luck!

Hi, when I load map with this asset, it gives me this message:

Broken assets:

Custom Assets: 796007336.Joak's Int'l Airport (Rail)_Data: NetInfo missing [BrokenAssetException]

Details:
No details

Which mod do I need in order to use this asset? Is there a Rail-data mod? I have one for trams installed for custom rail tram stations, which works, perhaps, that is the exact issue here? Thank you for your reply.

@dgascoine1 Thx for the info. My game was broke after the new update, and I probably won't update this anymore. I might do one with vanilla/AD airport sometime in the future.
