Larry- Glad they guided you thru the slow way to get the trucks loose.
I discovered a much faster way a couple weeks ago. set the engine on the track next to the edge of the layout where it is convenient to reach. Reach out and hook the cuff of your shirt sleeve on the headlight, then immediately pull your arm back to your chest in one smooth powerfull motion. When the engine hits the floor, the trucks become disassembled.
Depending on the gravity to height ratio, other parts dispurse to the far corners of the room.
Gathering up the many parts takes more time than taking it apart the slow way. Hope you can learn from my experience.
