The PRR's position light signals came in a small size too, known as a dwarf signals. These were usually placed for better visibility by crews at sidings and some yard tracks. High signals as seen in the background are actually aimed at a higher elevation so that the light will strike an engineman's eyes. I always wanted to get a dwarf signal for our back yard, but it never came about. [July 1976, Hudson OH Nikkormat FTn, Plus X]
