Reversing loops dilemma

[ggerrells]

I want to add two reversing loops to my existing layout. One of the loops will be simply a return loop. The other will surround a busy classification yard. I do not want to reverse the "polarity" of the loop that surrounds the yard because that would require reversing the entire yard. I would like to reverse the sections between the loops and the existing layout. I believe that as long as my maximum train length is less than A-B and C-D, reversing the center sections will work. My concern is what will happen if two locomotives cross A and B, or C and D at the same time. Will this fry my reversing modules? Would a PSX-AR recognize this as a short and simply shut down until the short is cleared? Is there a better way to do this? (Sorry for the terrible picture - my scanner didn't want to cooperate) I am using NCE's PowerCab DCC system. Thanks

I believe if two locos enter the reverse section from both ends at the same time you will fry the controller, depending on which way it is set for. If the current is not reversed there should be no problem, you'll just have to time things very carefully.
Wiring an LED between the gaps in the rails to the rest of the layout will show if it's safe to enter or not.

Crossing the two ends of a reversing section at the same time will not fry anything, it will cause a short and either the PSX-AR or the main DCC boster will shutdown until it is cleared
