The cars nearestthe machine carry the ties and the rail cars are back of these. The rails and ties aie moved forward to the machine cai asfollows: The construction train consists of ordinary flat cars, eachequipped with two flanged rollers, one on each side, 7 ft. center lOcenter, equidistant from each end of the car. The rails are fedto these rollers from the rear cars by a hoist, and are connectedtosethcr by inserting one bolt in each end of their angle continuous line of rails thus formed on either side, from therail cars over the tie cars and to the machine, are utilized as tieconveyors. The tie cars arc provided with a crossing plank onwhich the ties are loaded so as to permit the rails to pass over therollers and freely under the ties. On each side of the machine car, 7
