HARRIS TRACK LAYING MACHINE. continuous tramway or track (about eight feet sixinch gauge) laid and spiked firmly upon the topof a constiiTction train of platform cars. Uponthis tram track runs a small automatic car, de-signed for canying ties. Cast-iron rollers areplaced in the center of all cars that are used forcaiTying rails. In fitting up cars for the machinefive ties (ten and one-half feet long) are fastenedfirmly across each car. Rails are then selectedfrom those to be laid in the permanent track, andspiked to the ties, thus making a track (eightfeet six inch gauge) thirty feet long on each carof the train; short adjustable pieces of rails areplaced between each pair of cars to connect thepermanent rails, and which permit of theu easyremoval after the train has been unloaded, andtheir ready replacement again when the nexttrain comes to the front. The front or pioneercar has a frame work or extension permanentlyfastened to it, which extends th
