wow, i tried to remove the screws from the bottom of the car, to lift the shell off. i will look at the end caps and try it. thanks, really helpful tip.
It should work but the sliding out and back in is tedious. If the car has lighting, you also have to check that the wire from the trucks to the light board is detached; it is usually close to one of the end caps. (Lionel's 21" ABS cars are an advance over the old construction because they are meant to unscrew and lift off relatively easily - provided that the double-sided tape they use to affix windows has not been put between the shell and frame as well.)
