An original mile marker watches over the Sunnyside Ave grade crossing.
Since the time of this photo it has been painted white.
I've been pondering the design of these stones. When you stand
edge on and observe them, you see Baltimore engraved on the left, and
Washington on the right. That makes sense since the cities are in
When viewed from a moving train, however, most of the time only one
engraved side is in view at any given moment. The view from a
Washington-bound train is much like that in this picture. Under
such circumstances, the stones are confusing. This one gives the
impression that Baltimore is 28 miles ahead, whereas in reality it
is 28 miles behind.
Of course in 1835 the engravers did not have for reference established
standards like interstate highway signs. Another possibility is the
railroad relocated this stone from the other side of the tracks.
