FIELD: railway transport. ^ SUBSTANCE: proposed track machine has frame 3 made for movement under action of running mechanisms 2, endless chain 7 for loading ballast 10 made for displacement in height, device with belt conveyor 22 passing in longitudinal direction of machine and used to transport ballast 10 from chain 7 to ballast re-loading end 21 found on rear end 18 of machine, and other device with belt conveyor 25 for transportation of cleaned ballast 16 from loading end 24 on rear end 18 of machine to ballast unloading point 26 found after chain 7, viewing in working direction 5 of machine 1, and ballast loading end 19 on front end 14 of machine connected with its own device with belt conveyor 17. Ballast re-loading end 15 is found on front end 14 of machine and on rear end 18 of machine connected with its own device with belt conveyor 11 to transport ballast to car or from car for screening ballast material 29 which is connected alternately to one of two ends 14, 18 of machine. Distance in height between ballast re-loading end 15, 21 or loading end 19, 24 and rail track 6 is equal at each end 14, 18 of machine. ^ EFFECT: provision of removal of wastes formed et cleaning of ballast. ^ 2 cl, 2 dwg
