Thanks for the suggestions, emails, and Bill at the Atlas service department. An additional issue was discovered with the Atlas CZ cars. Some of the uncoupler lever buttons hang way to low and only have a 1/64 clearance. The steam and air hoses also seem to be too low and catch on switches. The steam hose comes off easy, the brake line not so easy. It actually needs to be bent up. The whole coupler needed to be raised. I did try to use nail polish to insulate it from shorting, it wasn't sufficient. I found that several of the couplers had to have the whole adjusting bar removed to tighten the mounting screw that allow rotation along with changing the height adjusting screws to a higher position. Running better.
Again thanks.
