Also I have to say that these cars are the most built into a corner of any toy train item I have ever experienced. I can't imagine how they got the screw under the one truck into the thing with the truck attached. At the least, you would have to remove the other three screws and then remove the last one under the truck while removing the frame of the car so the screw can stay under the truck as it comes out. And go back the same way.
The trucks do not attach from the outside, there is a retaining clip on the inside to secure the truck. I managed to destroy the truck on the SF cam caboose (by pulling the mounting collar out of the truck...which does not seem to be swaged back in without a new unswaged collar) just to see how the heck the thing is put together. It would be nice to just remove the cupola, but the retaining arms are prevented of being pushed aside by the LED lighting strip.
I ended up removing the camera assembly from the SF car which I actually had planned to do, and decide what car/engine I can put it into the front of so I can see everything going down the track. The camera assembly consists of a 5 volt regulator card, a switch, pushbutton, camera on a long flat cable and the camera microchip and antenna bundle. It would take some room...the most convenient would be a box car or some such with pickups on the trucks. Be nice to get it onto an engine, but not very likely unless ugliness is acceptable.
