Abstract
It is now admitted by civil engineers and other railway experts, that our American system of track which has done so well in the past, owing to its strength, elasticity. and economy of first cost and maintenance, is now in a bad way, and must be modified in some manner to meet the ever-increasing weight of cars and engines. This has grown during the last fifteen years from 5 tons on a locomotive driver to 9½ tons; and 3 tons per car wheel to 5½ tons; and the encl is not yet. Our track is giving out at all points. Joints which did well under lighter loads, now sink and allow rail ends to be battered down. Steel rails are not hard enough. Their heads crush, or the material itself flows under the heavy wheel loads.
