A train signal to control trains on a track.

Properties

aspect : Int

The aspect of the signal. The aspect shows if a train is allowed to pass (clear) or not and if it should dock. 0 = Unknown 1 = The track is clear and the train is allowed to pass. 2 = The next track is Occupied and the train should stop 3 = The train should dock.
