HO 12X28 foot exercise

While some folks suggest using fixed benchwork depths everywhere, _modulating_ benchwork depth can yield interesting results, as seen here. It all depends on what one wants to accomplish with their track plan. Inspired by this thread http://cs.trains.com/mrr/f/11/t/230412.aspx This 15 minute exercise is not at all a finished plan -- the yard area is not logically connected for example -- it's just an exploration of benchwork depth in a relatively narrow room.
