Cut and Slide
Conversion of bolted rail to Continuous Welded Rail (CWR) by the removal of joints in-track is a cost-effective method of making track smoother and thus a more maintenance-friendly infrastructure. When cutting out the sections of rail with bolt holes, sliding the remaining rail ahead, and making flash-butt welds at the resulting joints, the finished rail becomes CWR without the expense of installing new CWR and removal of existing sticks of bolted rail.
