Nice review. I have a set of these in SP colors....just because....and since I got them they went back to Lionel for over a month for being defective out of the box and then a smoke fan motor failed which I since replaced.
I really like them since much of my layout is O36 Fastrack. I do have one question on the Kaydee couplers. Could you show what you did to install them and do they still allow O36 operations?
Thanks again for a nice video!
