New stations and tile info

[XeryusTC]

I am currently cleaning up the code of Red*Star's modern station set and I ran into a bit of trouble. I need to be able to change the sprite of certain tiles only if a certain tile is adjacent to it. This other tile is not even in the same class of stations (might not even end up in the same newgrf) so I was wondering if this is even technically possible or should I just switch sprites when there is just any station tile adjacent to it as I currently have?
With a quick look at the wiki I suspect that variable 68 could help me out here but I'm not entirely sure whether that is so.

On a different note I wonder if it is also possible to have two different callbacks for the same station tile. I want to be able to change the appearance of a tile and also enable/disable animation on it depending on its location. I have no clue if that is possible though. Should I possibly use station property 11 instead of callback 14 for changing the looks of the station and then use callbacks for the animation?

That will cause you problems, it appears. Keep the two station definitions in the same GRF, and var 68 should be useful.

You can't have callbacks for station tiles at all. Stations, yes, but not tiles.

Thank you, I will keep the station definitions in the same newgrf then.

Well, the same question applies for stations then.

Of course you can. Newgrf wouldn't be very useful if a given vehicle/station/whatnot could only use one callback.
