Geography:
Hilly in town to mountainous outside of town to both the east and west
The Scoop:
This page covers signals which you don't see much any more.
Not railroad signals, but signals for vehicular (auto) traffic.
Years ago, some towns used to install "semaphore" lenses into their signals,
The idea behind this was to make it easy for color blind people to tell what "color" the signal was,
Obviously, the idea was inspired by railroad semaphores,
This signal was made by Eagle.
I don't know of any left in the Baltimore MD area where I live,
The last ones I know of were taken out-of-service around 1990 - they were on
Charles St in Towson near the School Sisters of Notre Dame.
I found two signals in Hagerstown MD, at Mulberry and East.
Another signal across the intersection only had two semaphore lenses in it.
An elderly woman came out of her row house and asked if red-light cameras were going in as I was taking pix,
She said they were badly needed at this intersection.
Looking at the Google Streetview pictures taken in 2015, the whole intersection has been reconfigured, so
the lenses are probably in someone's personal collection! :-)
