Abstract
Apparatus for aligning and setting the gap between two rail-ends prior to joining these two ends by fish plating or welding and possibly dressing the weld, comprises a rigid horizontal frame of open structure overlapping the two rails and providing an access area around the two ends to be joined. Two main presses and two end presses are mounted in line on the frame and arranged so that the two main presses are located between the end presses. Each combination of a main press and an end press serves to grip one of the two rails to be joined. The gap setting means can be locked on the two rails and has rams for moving the rails together or apart. Weld dressing means for eliminating the weld bead formed after a weld joining operation comprises a dressing tool movable by the aforesaid rams. The apparatus is especially for use in laying or reconditioning railway lines.
