I just bought a Kato corrugated passenger car set. They have the molded couplers installed, but came with Kato’s replacement knuckle coupler. The molded coupler will be replaced either by the new Kato couplers or MTs. Has anyone had any experience with these new Kato couplers. Magnetic operation is not an issue (I use a bamboo skewer), as long as they will stay coupled and can be uncoupled without derailing is fine with me. I bought some MT couplers at the same time and have converted other Kato passenger cars.
