Hi Pete:

Thanks for that suggestion. Is this the item you were referring to?

https://www.allelectronics.com...omotive-relay/1.html

If yes, please let me ask a few complete beginner's questions:

This is a 12V DC relay. What do you use as your power source? A DC transformer under the table? Something else?
I'm interested in using relays for an old-fashioned insulated rail-operated block system. What relays would be best for that application? Do those relays need to be AC relays since they will be activated by the wheel's of the train passing over the insulated track sections? Or would the 12V DC relay being discussed here be able to be used?

Thanks in advance for your help. I'm not an EE by any stretch.
