Hi John, I started to change over to kadees about 2 months back, easy to do when stock is new and has the pockets to allow quick coupling swap and height check. Old stock of various manufacturers has slowed things down somewhat and of course, for me , budget also to consider. Have been using a converted wagons at either end of fixed rakes to let me try, and practice uncoupling and shunting. Results are mixed. Wagons moving too freely to allow positive opening of couplings,but one of the experienced op's on forum posted a tip for fitting a pad to bottom of chassis to create some friction to axle, thus elliminating sloppy rake,and it helped a lot. However layout season has come to an end, and brown trout season for me starts in the next couple of weeks, depending on fly hatches etc. gear to be prepped, and that's after the garden work. 😀 Please keeped us informed as to your progress and your thoughts, as I still follow threads in forum throughout year. Hugh.
