Thanks, I got the two mixed up. I guess I'll convert to the newer dummy knuckles! 'Sfunny, we had a bully in High School named Dummy Knuckles!

I, too, have a mixture of old and new Bachmann rolling stock, and the two types of couplers aren't compatible. Is the 'dummy' knuckle coupler the one that looks somewhat like a real nuckle coupler, and the newer couplers have a sloping front surface? Can the old ones be replaced with the new ones? I've been out of N scale for about 15 years, and I now have a grandson who's old enough to appreciate the art form! Guess what he's getting for Christmas? ANY help will be gratefully appreciated
