  • Your BD8 Block Occupancy Detector is the latest in train detection systems.
  • It works with layouts using either Command Control or DC Control systems for operating trains.
  • In addition, for DC Control systems, the BD8 can report block status in either “OCCUPIED-VACANT” form, or it can report in “VACANT-STANDING-EAST-WEST” form.
  • With the OCCUPIED-VACANT form of output, your BD8 is all you need for two color signaling.
  • The VACANT-STANDING-EAST-WEST form of output is particularly helpful with hidden track.
  • By having two LED’s on your control panel, both will be on if the block is occupied and no cab is selected; when you select a cab, only one will turn on to indicate the direction the train will move.
  • Built in self-test functions to assist in installation and trouble shooting

  • The BD8 user's manual is now available for free download on our website
