old Con-Cor cars no longer derail!

I had about 20 old Con-Cor streamline smooth-side passenger cars from the 80s/90s. They were derailing on every switch, and I found in forums they are notorious for derailing. I tried these axles, and now they are running very nice! These axles are well worth the money to save these old cars, because new cars are expensive! I also used 10-702 couplers to upgrade the old Arnold couplers. Thanks to PlazaJapan, I did not have to throw away the cars I bought many years ago, and they are beautiful now!!
