Well gentlemen, I have failed in my efforts. I have been able to hook up the #415 Lionel signal bridge using 14vac and a MTR-12T relay from Scott's Odds & Ends. It works perfectly. But of course as soon as the train leaves the isolated track section the lights change back. Starting over - can either of you describe a circuit that will allow me to delay the light switch back for even a few more seconds after the train exits the block? I can only assume that I have hooked up the capacitor and the small initial resistor the wrong way. But now I'm stumped.
