Before I move on to the next railcar I beg your indulgence while I brag about getting a believable "look" to the rear running lights. The rear facing lenses are tinted red with the other three are tinted green. The light from the internal bulb is quasi collimated i.e. the lamps appear illuminated only if viewed close to on-axis with the lenses. I wheeled the caboose back into the dark factory to get a better view.
