Inclusion of a Holland MobileWelder® in rail installation projects enables rail to be de-stressed as it is initially laid, thus eliminating the expense of unfastening rail posts to thermally adjust it to its proper neutral temperature. Time, manpower, and needless temporary anchor / spike / fastener removal are eliminated, making rail installation to correct NRT a one-step process. Utilizing a Holland MobileWelder® and 160 ton rail puller, we tension the rail - compressive forces are minimized by cutting the rail section and then stretching the rail section to neutral forces. A Holland flash-butt weld is then made; once cooling of the weld occurs, rail pulling ceases and the rail is re-anchored.
