This was a vital North-South Western Union telegraph connection from Boston to points north (Maine and Canada) and south (Providence, New York City and further connections). This line was built with 6-pin construction as you can see. It likely was constructed in the 1890s and had double petticoat glass insulators and iron wire upon it. An extensive line rebuild with new (cedar) poles, 10-pin crossarms and hard-drawn copper wire around 1912 superceded this important circuit with plenty of CD 152 and CD 145 insulators. Some hardware and insulators were re-used, the latter as long as the glass was of the double-petticoat styles (existing or former double-petticoat WU styles).

The teen's Western Union pole line stood in place until the early 1960s when the copper lines were removed. Some of the poles remain standing, long-forgotten along distant right-of-way without any purpose in places in suburban towns and with crossarms, deviod of insulators (along this Amtrak right-of-way).
