These ties weigh about 125 SUPPORTS OF THE RAIL 97 pounds, and cost $ The ties are apparently giving excellent service. Theaxle load on this road, however, is not heavy on the light grades, and on themountain grades, where axle loads as high as 50,000 pounds are employed, the3 slow. 4- -O HALF LENGTH OF TIE. _ PLAN. Fig. 64. — Mexican Railway Steel Tie. (Am. Ry. Eng. Assn.) Buhrer Concrete Tie. — (Fig. 65.) About 600 of these ties were used onthe Pennsylvania Lines west of Pittsburg during 1903 and 1904 in stone 500 were subjected to heavy and high-speed traffic and the balance tomedium traffic. The ties failed under traffic, the concrete breaking and crumb-ling off from the reenforcement. The ties were removed from time to time andby December, 1906, all had been removed on account of breaking. STEEL RAILS ■a - D \ 1
