FIELD: railway transport; track maintenance. SUBSTANCE: proposed machine 1 has frame made for movement along rail track 10 by means of travel motion mechanisms 8 and consisting of three parts 3, 4, 5 interconnected by hinge joints 6, 7. Middle part 5 of frame is connected with two crawler running mechanisms 12 spaced crosswise in direction of machine movement and made with possibility of re-adjustment in height by means of drives 13. crawler running mechanisms 12 rest on ground bed making it possible to elongate rail track section 17 under reconstruction at reconstruction of ballast bed. EFFECT: enlarged operating capabilities. 5 cl, 3 dwg
