Hello, all:

This thread on the evolution from semaphore to
position light (PL) to color position light (CPL)
signals has been interesting.  I am wondering if the
installation of PL signals on the Hagerstown District
was much earlier than the conversion elsewhere on the
system.  The reason I suggest this is that photo

understood to be a 1921 picture.  By this time, the
block limit signals on the train order mast have been

If anyone can't find the photo I'm referring to
easily, please send me a message at f_scheer at yahoo.com
and I'll attach it.  All information is welcome, since

with restoration of a CPL signal, train order signal,
or crossing flasher to be erected behind Boyce
station, I'd welcome hearing from you.

Best wishes,
