Abstract (en)
[origin: WO2017158500A1] A machine (10) for repairing a ballast bed (12) comprises an undercutter (26) that defines a direction of movement (16) of the repairing machine (10), a distributor (28) for dividing a flow of ballast entering from the undercutter (26) into a rear flow of exiting ballast and a separate front flow of exiting ballast; at least one rear screening machine (36) positioned behind the undercutter (26) in the direction of movement and fed by the rear flow of exiting ballst; and at least one front screening machine (30) positioned in front of the undercutter (26) and fed by the front flow of exiting ballast, the distributor (28) having a variator for varying the ratio between the separate first and the second flows of exiting ballast.
