"Mark's Addiction” is an ambitious new layout which occupies a 1,200 square foot area in a custom designed home. This O gauge model railroad is set in the mostly 1930 - 1950 era, however some modern motive power and rolling stock occasionally slip in. Trains which appear on this layout are from the New England States, the Pacific North West and Canada. This layout has been constructed over the past few years. This is an ongoing project that truly makes optimum use of the owner's hobby time.
