I am using a Logic Rail Grade Crossing Pro. It is a full function grade crossing circuit that can handle flashing crossing lights, motor control for gates, and a bell circuit. The user has to provide the lights, gates, motors and bells. In addition, if using LEDs, the user has to provide the appropriate resistors.

circuit to the benchwork
Even though I was only using the crossing lights, there were still 14 different wires that had to be attached to the circuit and run to different spots on the layout. I made a wooden chassis with a terminal strip to try to help keep all the wires organized. I engraved letters on the wooden chassis for each connection. The large letters are easier to read when the circuit is mounted on the layout upside down. I also built harnesses for the wires that I ran to each signal and photocell. I used heat shrink tubing to make the harnesses. Unfortunately the magnet wires that came with the signals were fragile - two broke in the harnesses and two others shorted inside the tube. So I replaced all the magnet wires in the model signals with 32 gauge stranded wire.
If I turn off the room lights the grade crossings will trigger if their power is on. So I have to make sure that switch is also off when quitting for the night.
Here is a video showing its operation.
