How to develop signaling circuit to control rail crossing gates, signals etc?

Hi Friends,

I know that its a difficult task to develop a signling circuit to control power in block on our own, but I am not much interested in spending too many bugs on cosly signaling circuits available in market.

Can any have a idea of simple circuit with use of LDR to detect train & controls rail crossing gates, signals etc?

Thanks,

Sanjeev

Google is your friend:

This guy has the circuit diagram out there for all to see, and will sell you the board and a bag of parts for what seems to me to be a pretty good price. When I get around to it, I’m going to order the parts from him and see how it works.

Mr. B:

I look forward to your review after you build one.

Have you tried “Logic Rail Technologies” I have some of their products that controls crossing signals and rail signals.
