@PRKTRAINS thanks for the detailed post. Yes you are correct on your steps and that all works, but…… I am having to push the WPS button on each WTIU every time I start them up to run trains so they link up. Being that they are under the layout that’s a pain for my old back. Do you have this issue? Someone has suggested leaving the WTIUs powered up all the time and turning only track power off??? I really don't like leaving things on like that. Any suggestions on your experience with three units are welcome.
