I posted some pics here a few months back of my "HO" scale Psycho Mansion interior in progress and like most hobbyists I like to have several things going at once. What I'm working on now might not be something your average railroader would include in their layout, but it is "O" scale and it is a scratchbuild. Just thought you folks might be interested.
