I'm looking for a grade crossing detection unit which will activate lights, bell and gates. I had a very old unit made by Roanoke Electronics which worked great but they have been out of business for years. Any suggestions. Optical detection would be great.
Does anyone know of any under the track electro-uncoupling magnets that are available or can be made? I have tried to modify a Kadee Electric with heavy steel washers but without great luck.
I would prefer to have nothing visible. Any help is appreciated.
