Situation: I have one set of my Tortoise relays powering the turnout frog. The 2nd Tortoise relay I am using for position lights (9V LED). I'd like to remove the lights and have the 2nd set of Tortoise contacts driving a multiple device relay/contactor set that can handle switching of several functions/devices. Essentially, expanding the Tortoise 2nd relay set to a multiple relay set. The added relay/contactor should of course be electronic. My first layout back in the day had small mechanical relays and the my train room sounded like an old elevator controller every time I threw a switch. Anyone ever tackle this? What electronic relays did you use?
