A new arrival on the layout tonight.  A 16 channel block detection unit that will allow me to know what sections of track have a train on them.  Another step toward being able to automate some of the layout.  Also a little bit of preparation for the new signals to add power wires and fine tails to allow me to reprogram them later if required.  Extras have a couple of close up shots.  Lots of wiring under the layout will follow soon.
