I would like to know what everyone uses to uncoupler cars during a typical car setting operation. Is there a particular tool used to uncouple Kadee couplers at the location you want to set the car at. Surely you don't place uncoupler magnets everywhere on the layout. Secondly, do you use switch machines on all of your turnouts or do you manually switch them? I am building a basement around the walls 12 X 20 foot layout and would appreciate any suggestions to my questions. I am really "out in the sticks" where I live and my town doesn't support any hobby shops.
