Just a bit off of the subject, but I am just completing the wiring of a 30' x 20' HOn3 layout using Micro Engineering flex track and turnouts.   NCE power for DCC with PSX cbs and PSX-AR auto reversers for loops.    Everything is running pretty well, but on occasion my Blackstone locomotives will stall on a random turnout, especially when moving slowly.  And often will start moving again on their own after a brief stall.  I don’t think it’s a short even though it acts like it might be.   Frog polarity is correct, in conjunction with the tortoise, and works fine 95% of the time. 

Any ideas what my issue might be?  Or is this just the nature of the beast? 

Thanks!
