WELDED RAIL IN THE U.S.A.
The elimination of rail-joint maintenance is claimed to be more than covering the additional cost of welding, transporting the welded strings to site, and handling them. In general, few troubles have been experienced. Expansion and contraction at the ends of welded strings has been little more than normal, and has been restrained by increasing the number of rail anchors applied over the last six lengths of rail (234 ft) at the end of each string. Given proper anchorage, no trouble is experienced with buckling, but that considerable care has to be exercised as to the temperatures at which continuously-welded rail is surfaced.
