I have just started to re-wire signals on a newly designed layout. The collection of signals and sensors however come from quite a few different manufacturers ? Lionel, MTH, Atlas O, Custom Signals, Z-Stuff etc. Each manufacturer has their own method of connection and signal detection. Since I was mixing signals and detectors I decided to put together a series of schematics showing how a signal is wired to a particular detector. The URL below will guide you to the PDF document.
While there is a lot of different signals and detectors shown the list is no where near complete i.e. MTH ITADs, New Jersey signals etc. So if anyone would like to post connection diagrams for signals/detectors not shown please respond. I will add to the PDF document as we go. Hopefully this PDF file will become a living document on this and the OGRR forum for all to use and enjoy.
