As in other new construction, the company uses as itsstandard a No. 0000 grooved trolley wire. The poles areof chestnut, 48 ft. long and spaced 100 ft. apart on tangenttrack, the spacing on curves reaching a minimum of 42 are set 7 ft. 6 in. away from the nearest construction is used throughout, and strain platesare employed in the trolley construction at the beginning.

Between Blandford and Huntington, a distance miles, a temporary route will be followed in which thealignment and grade will necessarily be less the line crosses the Berkshire Hills in their roughestportions, many heavy cuts and fills were necessary, andmuch reinforced concrete work has been used in connec-tion with bridge and culvert construction. The largestcut on the line, near Blandford, known as Tiffany cut, is Yz and end of every curve and at points 1000 ft. apart ontangent track. The brackets vary in length from ft., and the trolley lias a minimum clearance of18 ft. above the rail.
