From the top of the incline to meet-ings, the line consists of three rails, and the three rails joiningthe four rails at meetings by a V rail, obviate the necessity ofpoints, which would have been indispensable had there only beentwo rails on the top of the incline-meetings. From meetings, the four rails are continued to near the bottomof the incline, where there is a short length of single road fromthis point to the commencement of the full and empty roads(Figs. 3 and 4, Plate XXI.). The switches at the bottom of theincline are weighted, and are worked alternately by the loaded set Text Appearing After Image: Fig. 14.—Eastern Front of Drum-house. passing over them. At the bottom of the incline, there are alsofour sets of rails the full-wagon roads being on the low level andthe two empty-wagon roads adjoining each other on the highlevel. This is the reverse of the arrangement at the top of the-incline, but it is required in order that, in this case, the emptywagons may serve to the rope. All the sheaves are made of toughened steel, and the rollersbetween the rails are 9 inches in diameter by 10h inches wide(Figs. 5 and 6, Plate XXL), weigh 45 pounds, and run loose onthe spindle.
