Broad Street subway is an Atlas Comet commuter car in disguise. Any of several roads they modeled will do. Sides are covered with Evergreen clear plastic sheets for windows and recovered with Evergreen corrugated strips below the window line to simulate fluted stainless steel streamlined panels. Add downloaded pictures from prototypical photos (including those peculiar destination signs) and M.V. colored lenses and you have something resembling those colorful orange cars. Have used same technique for long modern cars from Baltimore, Boston, Cleveland, and Toronto. Takes a bit of time and patience, however.
