Hi all, Since I last MRR'ed there is an amazing amout of new cool stuff to be had. These magnetic couplers? how do they work, and more importantly how do you uncouple cars, how are uncouplers installed on the layout?/ Oh yeah, switches,, electric or manual?? which is the way to go. I will be running DCC. I hope to run both Diesel and Steam, if my plan permits Thanks Tony.
