Three Track Bridge Block Signal

Volpin,  This is two Lionel 450 double light bridges.  I cut them both and took a piece out of one and used plastruck beams and joined the center piece, left and right legs together.  This made it wide enough to cross 3 tracks.

I used 4 of the Lionel 2 aspect lights on each side and cut a WeHonest 2 aspect light for the center.  Now I have lights on the front and back side of the bridge. That's a total of 6 lights.

I used 22 gauge wire and strung it along the lines of the bridge and down the legs.  Then placed one WeHonest control card, with an infrared detector under the center track.  Next was to place 2 MTH infrared detectors for the out side tract, both with the detector looking at the outside track.

Finally, I wired everything to the detectors and amazingly enough it worked.   I use 12v DC for all of my lights and accessories. My layout has 2 200w DC transformers. 

Click on this pic when open and zoom into the center, that is how it was lengthened.  The second picture shows test wiring and all three controllers.  The third picture is the WeHonest 2 aspect signal which I cut the bottom off and mounted the top, to the top of the bridge.
