Not long after this photo was taken this 1890s line was totally rebuilt from Boston, MA to Albany, NY with cedar poles, hard-drawn copper wire (replacing the former iron wire) and with three or four 10-pin crossarms per pole. A lot of the "new" insulators during the upgrade predominantly were CD 145 "B" beehives, CD 152 Brookfields and Hemingrays. Double petticoat insulators notably CD 145 CREB Brookfields were re-used as well as some line hardware particularly metal pins (with wood cobs) and crossarm braces. This line always has been a busy one, extending west from Boston. The latter pole line stood until it was totally removed in the late 1980s. Several CD 134 Diamond-P insulators were found along it by the late Richard Gay of Worcester, MA from walking the approximate 50-mile stretch between his hometown and Palmer while the pole line was still standing. The railway extended across the upper hillside section of his backyard and he was totally fascinated by finding a half of a Diamond-P around 1977 near the tracks. This discovery kindled his fascination for Diamond-Ps and insulator collecting. At least another collector or two found a few more Diamond-Ps along this line through the 70s and 80s, all still in service (upon signal/code wires). Albeit widely scattered, two were located on the same pole. A number of CD 162 skirt embossed Brookfields in varying shade of purple were located in 1970 upon the code and signal circuits along a short stretch of this line in Framingham, MA near the General Electric Clock Works Factory.
