Here is my modified 77 crossing gate. I removed the solenoid and used a servo motor with two sets of IR detectors. The bulb is a screw in LED replacement similar to what I have used in passenger cars. I was surprised that it worked well at 5v DC. Now I do not have to be concerned about the solenoid getting hot if the gate is down for a long period of time. The gate can still be put back to original configuration if desired, no holes drilled or components changed. I used a solid copper wire with a short piece of elastic an the end for the actuating rod.
