An update on the electrical “Gremlin” situation that led to this thread on the forum.
Because, we only run on this layout on the first on the first Saturday of the month, we have had time to fix the problem after our run day on Feb 5th…. The run time on Feb 5th went quite well and we were able to run conventional, DCS with the handheld and using the WIU with smart phones. As you can imagine, the smart phones were smarter than some of the older users, but the 4 year old visitors who used the phones showed “the old guys” how to do it, so we were OK. 
Using the suggested fixes from members of the forum, the trouble shooting crew “attacked” the problems yesterday and all the issues were fixed. We found that one of the connections on the ground side of one section of track had been bent to the point of not making contact. We fixed that. Then, we rewired the blocks to the SPST toggle switches to break the “hot” leads at each end of the block and everything worked just fine.
It’s most interesting that all this started by wiring according to the diagram on page 14 for the O31 turnout manual, which didn’t work for us….
Now, when we run conventional locomotives, either or both tracks can be powered or not. When running DCS, all tracks are powered and the controllers (DCS hand held and/or WiFi) will operate the trains.
Thanks again. We are most grateful for all the help.
