This was a couple of days ago, and is a minor thing compared to layout-construction progress reports, but it was very significant for me, for it led to being able to operate my DCS locomotives again after a problem that rendered all but one of them unable to run under command, a situation that I first became aware of in January 2021, and left my test-track loop out-of-service until a chance thought led me to swap polarity at the lockon..
Before this, none of my locos save for one that was already on the layout, could be found by my TIU. I never thought to check my wiring because the diesel that was on the layout was unaffected by the wiring error (and my loop is only able to accommodate one train at a time). The full sordid story can be found in the MTH DCS sub-forum here.
