Then the March 13, 1909.] ELECTRIC RAILWAY JOURNAL. 457 surfacing gang made the first lift and brought the railspractically up to their final height. The second ballasting operation was similar to the first,with the exception that a piece of 4-in. plank 4 ft. 6 was bolted below the push board and between therails. In pushing back over the second layer of ballastthis lower board cleared the space between the rails. This. Joplin & Pittsburg—Stringing Wires on Trolley Pole Line made it unnecessary for the workmen to shovel any ma-terial off the top of the ties. With practice the men coulddump just a sufficient amount to properly ballast thetrack, leaving material for the i-ft. slope on each end ofthe ties. A train of eight cars could be dumped in from20 to 25 minutes. In ballast hauling three 80-ton, 10-wheel locomotives were used. The older line from Pitts-burg to Columbus is ballasted with smelter cinders, whichafford a very solid roadbed. OVERHEAD CONSTRUCTION The pole line for the support of the catenary and feeder
