Just to make sure, are these the correct locations for the J1 - 1a and 1b leads to connect and do I need insulated rail joiners where indicated?
Though technically the answer is yes, you don't have to limit the size of the isolated section to the size of just one piece of track. You can add another section of track and then place an insulated rail joiner on that piece of track. You can make that isolated section of track as long as you want. A longer section of isolated track will limit how often the circuit board relay trips. If you just have a short section of isolated track, the relay trips every time a new truck passes onto that isolated section.
Great - I got it to work. Just need to determine the optimal length of the isolation sections! Thanks everyone who helped shorten my learning curve :-)
