SYSTEM AND METHOD FOR REPLACEMENT OF TRACK BED BALLAST FOR RAILROAD

摘要

A working train (51) of a one-line unit system includes hopper cars (53a to 53e) with new ballast (NB) loaded thereon and a ballast working car (52). The ballast working car (52) has out-conveyors (57a, 57b) for allowing already laid ballast (B) to be scraped up and the scraped-up ballast to be conveyed onto a rearmost hopper car (53e) and an unloading conveyor (58) configured to unload the new ballast (NB) into a dug-up site (21) where the ballast B has been scraped up. The hopper car (53a, ..., 53e) has a first belt conveyor (61) which conveys the ballast (B) onto a forwardmost hopper car (53a) and second and third belt conveyors (62, 63) which convey the new ballast (NB) onto the unloading conveyor (58).
