EZ-Mate magnetic couplers

[Swampcrawler]

Are the EZ-Mate magnetic couplers compatible with the  EZ-Mate Mark II couplers?

They're really the same thing. The only difference is what keeps the knuckle closed. The mark I's use a small plastic whisker while the Mark II's use a small metal spring to apply pressure to the knuckle and keep it closed.

Good Morning,

       As mentioned,  the EZ Mate Mark I has a plastic whisker to keep the knuckle closed.   That is why you stay away from the Mark I.   That plastic whisker can and will fail.  If you want to use any of the Bachmann plastic knuckle couplers use only the Mark II with the coiled spring on the knuckle.
