Constructor & Destructor Documentation

◆ Station()

Station::Station ( TileIndex  tile = INVALID_TILE)

Definition at line 63 of file station.cpp.

◆ ~Station()

Station::~Station ( )

Clean up a station by clearing vehicle orders, invalidating windows and removing link stats.

Aircraft-Hangar orders need special treatment here, as the hangars are actually part of a station (tiletype is STATION), but the order type is OT_GOTO_DEPOT.
