I have a DC Bachmann 0-6-0 switcher with a slope-tank tender. I can't figure out how to get the body off either the engine or the tender.  I've managed to remove enough screws so that the rear of the engine body is loose, but the front is still firmly attached to the frame, and I can't find any more screws. With the tender, it appears that I should be able to just pull the body off, but so far, spreading the plastic doesn't seem to work, and I can't pull a lot harder.  I'd appreciate any hints.  Thanks!
