Believe it or not, the Smithsonian Institution actually has a Magnetic
Signal Company wigwag on display! This one stands inside "Railroad Hall"
on the first floor of the museum in Washington D.C. It's an immaculate
example of a Southern Pacific "style" wigwag. The plaque behind it simply
reads "highway crossing signal 1917". No further information is given on
where it originally served. Notice the wire that is holding the banner
in a "swinging" position. I'm guessing that this one is not operational.
It is said that this wigwag came from Pleasanton, Ca.
