I decided a few months back to make some major changes to my railroad. Tearing down a big piece to make things “better”. Up to yesterday things were going well then I ran into reversing loop issues that my brain just could not figure out! I have included a diagram of the overall railroad. Nothing to scale and a lot of stuff missing but the point is just to show reverse loops and my thoughts on power districts. A more detailed drawing is on the right side of the diagram to show how the “mains” meet into the staging area.

When I use my Withrottle it will not display the dual throttle mode.  That is the mode in which it displays 2 throttles on one screen.  It used to display dual throttles, but stopped doing it.  I can't find any setting for "dual throttle" display. How do I get it back?  I have googled the question to no avail.

One more nagging question I have as I start to get my basic wiring setup:

How do you make power supplies safe from accidental contact with 120 volt supply?

As seen in the picture the MeanWell power supplies which are supposed to be the best have no real protection from the high voltage connections. Ironically, the cheaper power supplies have a thick piece of plastic that snaps over the lugs once all are tight. 

I'm using a WiThrottle app connected to a DSC51 w LNWI.  The WiThrottle app and DSC51 keep fighting with each other.  When using the app it keeps getting interrupted by the DSC51 speed setting.   If the DSC51 has the brake on it will stop the app until I make an adjustment via the app.  If the brake is off whatever the speed the dsc51 is set to will interrupt the ap and change the speed.  Any ideas on how to fix?
