Span, with Middlebury Station in Background spiraled and protected by guard rails. Sheffield iron cattleguards arc in place at all crossings. The overhead line is carried by chestnut poles with topsat least 22 in. in circumference. Between Waterbury andthe substation there is an 11,000-volt transmission line ofNo. 4 solid copper wire on Crown No. 2 porcelain insu-lators disposed in an equilateral triangle 40 in. on a side,the top insulator being carried by a pin on a short cross-arm. The poles here are 40 ft. long, 1ml where there is no transmission line 35-ft. poles are used. The trolley is grooved wire with flexible bracket suspension and isfed every 1000 ft., the construction being the ConnecticutCompanys standard for new lines.
