Have you checked the traction tires on the problem engines. since the problem seems to be power, perhaps the traction tires and spacing of the trucks is causing the issue. perhaps the trucks are loosing contact with the switch which will cause a power loss.
The problem with older Atlas switches is they used a very fine wire to connect the different center rails, and one overcurrent episode would burn out the wire and leave that rail unpowered. The fix was to run a more robust jumper. We had to do a lot of those on our club layout.
The TMCC N&W J stalled & blinking lights, at the spot just passed where I replaced the Atlas switch with a straight. Sounds like there is a signal issue in that spot that does not affect the PE Berkshire. I think I'm going to try to jumper wire the switch I removed as per Johns suggestion, and place it back where it was. But jump from where to where?

I love mine. No tool box should be without one.

I ordered my Mianne benchwork at an October York Meet ... it was delivered 2.5 months later. The time did cross the Holiday Season which, I'm sure, made a difference.
In any case, it was worth the wait.
