According to my old 1953 book from Lionel, you can control block signals by using the "Non-derailing feature"... Normally, you would hook up three wires from the switch controller to the switch itself. So, in the case of a Lionel 153 block signal, it appears that you parallel the three signal terminals to the controller leads at the switch. Correct ?
But in the case of a Lionel 151 Semaphore, the sketch seems to indicate that lockon-provided track power goes to two of the semaphore's terminals and the third terminal goes to one of the three terminals on the switch. Right ? Could anyone expand on this a little bit ?
Yesterday I panicked because either a large ZW controller or the smaller lever next to it, would operate the same train. I knew I had a crossed wire somewhere. Gave up until this morning when I would be more "fresh" and not tired !
Found a wire going to a Lockon that should have gone to the nearby Lockon on the far side of the fiber pin. Corrected same. All is well !
