Hello Stan,
Thanks for the next level of detail and yes i do understand operation, I am studying operation of the relay, but in general I get it. As for track power, i would be using phased ZWs. Steve Horvath has spec'd the signal system, and he suggests you contact him for signal operation/wiring details. His email is shorvath@atlasrr.com or phone 908-687-0880 x7142.
Whatever labor you guys want to work out is fine. I do appreciate your help. I have attached the block and signal schematic for your information. feel free to contact me as well, should you have additional questions.
