Bachmann Trains E - Z Mate Mark II Magnetic Knuckle Couplers with Metal Coil Spring - Medium (12 Coupler pairs per card) - N Scale

I would just like double check that these are indeed n scale medium shank couplers?

Will these work with kato?

How to setup dcc?

I have an older set of n scale cars with rapido style couplers, but my new bachman locomotive has the new/smaller style. would these work? Replace?
