      Brian called it correctly...a piece of track normally furnished with
      roundhouses and engine sheds to keep locos from ramming into the back wall.

      Diodes conduct DC power in one direction, but not both. When the last power
      pickup wheel of a loco crosses over the gap in the rail, the loco will stop.
      However, if the polarity of the power pack is reversed, the diode will
      conduct, and the train will be able to reverse its direction and move again.

      I might be useful close to the end of a siding...to keep locos from running
      off the end of the track. Check to see that the diode is pointed in the
      "desired" direction of travel before you fasten the track down to the layout.
