Randy, I am looking at Stan's picture posted from the manual and it only shows 4X which break the outside outer rail connections. If you follow the inside outer rail from the main line (which is powered when that lock on is in the position shown), through the switches to the A line there are no X on that inside rail. The outer Rails show the X but that is the insulated non-derailing section.
Do you have a Voltmeter. If so place one probe on the switch inside outer rail (the section that doesn't show an X and then touch the inside outer rail from the curve piece attached to it. If there is continuity the train will have black line common available. (test both switches) Since center rail is powered the train will have power. Since the lock on light of the A line is on the other outside rail it will remain unlit until a train goes in and the wheels bridge both outer rails. At that point the lock on lights even though your switch is on the B line. G
