This was a main route for both the telegraph and railroad lines between Boston, MA and Albany, NY. This telegraph line was built in the 1890s (replacing one using two and four pin crossarms). During the teens through the early 1920s it was again rebuilt, using 10-pin crossarms, hard drawn copper wire (replacing the former iron wire) and for the most part cedar poles also were set. Additional and replacement insulators on the new line principally were CD 152s and 154s (from my finds along it and observations).

The bottom crossarm likely carried signaling and/or communications circuits and were separate, belonging to the railroad. A lot of "signal" style insulators were used upon it. Numerous CD 134 Diamond P insulators have been located along the forementioned RR-owned lines, from a few miles out of Boston through the center of the state. They were very widely scattered.
