-Wagons in general:
- Players can only place/destroy wagons if they have train_operator
-Wagon driving controls:
- The former seat_access tables are unnecessary, instead there is a whitelist for the driving stands
- on player trying to access a driver stand:
- if is owner or is on whitelist:
- allow
- else:

-Wagon coupling:
- Derived from the privileges for driving stands. The whitelist is shared (and also settable on non-driverstand wagons)
- for each of the two bordering wagons:
- if is owner or is on whitelist:
- allow

-*"protected from" means the player is not allowed to do things, while "protected by" means that the player is (one of) the owner(s) of this area

-### Advtrains Privilege Guide
-All privileges are automatically granted to singleplayer, but for
-multiplayer servers this might be interesting.
-There are 3 groups of privileges introduced by advtrains:
-
-## Trains
-For a player to build his own trains and driving them, the player needs
-the 'train_operator' privilege. This privilege no longer allows him to
-control any train, only the ones that he owns or that he is whitelisted on.
-The owner of a wagon can write a whitelist which players are allowed to
-operate his wagon using the wagon properties dialog.
-Players having the 'train_admin' privilege can always drive, build and
-destroy any train.
-
-## Tracks*
-The area 1 node around and 4 nodes up from each track node is protected.
-Players that don't have the 'track_builder' privilege can not build or
-dig (or modify) anything inside this area.
-If any player tries to modify anything that is in the area of a track
-node and this track node is protected from him, he also can not do this.
-(that said, while checking protection, the area around a track is
-treated as the track node itself)
-
-## Turnouts and Signals*
-Players without the 'railway_operator' privilege can not operate signals
-and turnouts.
-
-* If the configuration option 'advtrains_allow_build_to_owner' is set,
-an exception applies to players missing the required privileges when
-they are in a protected area that they have access to. Whether the
-area is protected from others is checked by checking for protection
-against a dummy player called '*dummy*'
