Hello KRM.........
I am REALLY impressed with your work and JARK's work too. I wondered if it possible to make a Lionel 600 series NW-2 with double motors, metal gears, 4 axle mag-n-traction ? I would love to have one using a # 634 switcher as a starting point. The # 634 is my first switcher I had in 1965.
