A method for producing a beam for a travel way in a track vehicle system includes fabricating the beam at a production facility with dimensions corresponding to erected dimensions the beam will have at its construction site, or within a predetermined deviation from the erected dimensions. The beam is positioned in the position it will have in its erected state in the travel way at the construction site. Positions for connection points are measured and defined on the beam for appurtenances so that such appurtenances and functional surfaces will have a desired relative position on the beam in its erected state at the construction site. The connection points are reworked by adding or removing material as required so that upon mounting the appurtenances to the beam at the connection points, the appurtenances and functional surfaces will have the desired relative position on the beam at the construction site.
