Railroad rail profile
View Patent ↗A profile for the composition of a railroad rail with the provision for at least one pair of webs in each profile of the rail, in addition to being provided with a set of cutouts of a plurality of geometric shapes that allow the crossing of wires and cables for several purposes.
