It is also possible the 6-pin pole line was for telegraph service along this railroad right-of-way with the 10-pin crossarm circuits for telephone use. Although, commencing around 1910 Western Union and other telegraph companies (at least here in the northeast) were upgrading their old 6-pin lines to 10-pin construction. This provided for new poles, hard-drawn copper wire (replacing the old iron stuff) and crossarms with "updated" insulators; overall with more efficiency and additional circuits. The "updated" insulators were double petticoat ones replacing any single-skirted ones from the previous line. CD 145s and any other petticoat insulators generally were carried over to the new line if in usable condition.
