So at menards today I came across some 4.5 volt crossing signals, dc powered with a transformer ...scale-ish...problem is they are on all the time.
Does anybody know of a setup that will activate/deactivate 120 volt ac so the transformer power can be turned on/shut off by a passing train?
These are inexpensive little devices...just need a device to control the power so they can be made to operate similar to the real thing...
Any ideas?
