摘要： A method and apparatus for laying a railroad track includes laying, in tandem, a series of pre-cast concrete slabs on a prepared track bed, the slabs being isolated from the bed, and from each other, by rubber isolation pads, and the slabs having cavities formed on the top faces. The rails are held above the slabs, in their proper location, by removable gauge beams having adjustment means to exactly locate the rails. Before filling the cavities with concrete the shoulder-pins, used to secure the rails, are located with their pin portions in the cavities by being removably secured to templates. The templates are held suspended above the slabs by being removably attached to a rail. The rails are used as guides after setting their exact gauge (separation), elevation and cant (angle of inclination) on the gauge beams, to determine the positions of the templates and shoulder-pins. The cavities are filled to the level of the templates with concrete and, after the concrete hardens, the rails are lifted, the templates are removed and rails are lowered into place.
