Just tried it on both of the switches and still experiencing the rear truck hop.
I have however noticed something else with my flashlight, the trailing truck isn't resetting to center on the post it rotates on under the chassis. See the attached pictures here of the derailment. Its hard to tell but the trailing truck has no more room on the screw to swing as it is maxed out from the last turn it made and hasn't reset back to center. There is a grounding wiring one the trailing truck but it doesn't seem to impede movement of the truck at all. 
So with this being deduced I think now i have a good understanding as to whats going on. From the way I see it the engine goes around the turn just fine but the trailing truck is pushed to the end of its slot in the chassis. When the engine comes to the switch the flange on the trailing truck catches the plastic tabs used to actually throw the switch causing it to "hop" which in turn derails the locomotive. The question is how do I fix the trailing truck so it properly resets itself once the locomotive comes out of a turn onto a straight away?
