摘要

A mobile track renewal apparatus comprises a frame mounted on undercarriages for mobility on the replacement track in an operating direction during track renewal. Carrier arms extend forwardly and rearwardly from the mobile frame and respectively receive the new and old rails, the carrier arms being vertically and laterally adjustable in relation to the frame and fixable in a selected adjusted position. Similarly adjustable and fixable guides are mounted on the frame for guiding and laying the new rails.
