Relays for o scale railroad crossings

Several companies make and have made relays suitable for your application - if you can post a picture of your relay one of us should be able to identify it for you.

The relay was not made by a company or anything. It was made by a guy I met. I was wondering if there was a company that is very reliable and I don't have to worry about it breaking.

If you're using the insulated outer-rail method to trigger the relay, I recommend this relay module designed by OGR's prolific contributor Gunrunnerjohn:

Have a look at these controllers by Azatrax.  They have intelligent logic controllers.

I've used these with good success. They are AC relays and the bases for them are shown at the bottom of the linked page.

Here's a diagram of how I connected use them in conjunction with a traditional block signal and an insulated rail section.

And they are foolproof, bulletproof. Work first time every time.

Ditto on azatrax. Have several and they work great.
