Picked up a Bachmann E-Z Mate under track uncoupling magnet to try with my Kato Unitrack. Had to shim it up to fit lush with the underside of the track. With a little practice and patients. I was actually able to get pretty good at it. This is the first time I have every tried uncoupling magnets on a layout and I think I am going to enjoy them. Now just have to order a few more.
