Pennsylvania Railroad Signal

The Union Switch & Signal Company of Swissvale, Pennsylvania just outside of Pittsburgh, made these signals. They were unique to the Pennsylvania Railroad.  A design feature of this signal is the use of yellow lenses for the display of all aspects. They elected to use yellow because the lights would show up better in low visibility conditions such as fog.
