I do not know if is possible, but I gustari add a function that allows players to connect the rails or power lines without relying on the public service.
If you can do with careteras, why not with the others ?.
I would like to use this on the maps divided into regions (http://forum.simutrans.com/index.php?topic=15388.msg151671#msg151671).

How do the regions work? Surely allowing an overlap with building of 1-2 tiles (the boarder) between regions would work?
The borders are shared between the two players.
What if one was to force everything in the board to be owned by public service (change ownership on construction)?
The public service has access to all regions currently.
What I am saying is, what is stopping everything that is built on the 2 tile wide boarder from automatically becoming owned by the public service provider so people can connect to it?
It is possible, but the idea is not dependent on the public service for this.
