Still not sure about the Pensy Flyer.
However, I think that I have found the issues with the Berkshire Locomotive.
Derailing at entering the turnout switch: When going into the entrance of the turnout switch, that front truck seems to hit the tip of the switching point rail, and rides up, over, and falls down on the other side, and heads into the turnout. This of course tries to take the loco that way, causing it to derail.
Derailing at entering the back side straight of the switch: I have found that in one of the 90 degree corners, leading into that switch, the loco lifts a bit, and the back drive wheel slips up and over, and to the outside of the rail. It always slips over and to the inside of the turn, so I put a shim under the inside edge of that turn, at the point where this happens, and the problem went away.
This only happens at the one turn. See the pic with the piece of wood under the track.
