Laying track for Bombay tramways in a narrow street.

Original description: "Track Bracket Pole Construction in a Narrow Street. Rails are of grooved section weighing either 90 lb. or 96 lb. per yard. They are connected by continuous rail joints except on curves. The joints are double bonded with concealed No. 0000 flexible, pin-type bonds 12 in. long. The same bonds are used for cross bonding every 120 ft. between both rails and between the two lines of track. The ties are of principally Indian teak wood 7 ft. 6 in. long by 6 in. x 4 in. spaced 2 ft. 6 in. center to center. In laying the tracks a foundation consisting of a 6-in. layer of rubble stone was first deposited in the trench and well compacted by rolling. The ties were laid on this foundation with an intervening layer of sharp stone screen."
