The invention relates to a transfer car (100) for sleepers designed to outfit a railway vehicle of the type comprising equipment for laying down new sleepers (21) and/or removing worn sleepers (22), the transfer car (100) comprising an undercarriage (110) supported by at least one running gear (112), the transfer car (100) being characterized in that it comprises at least one traverser (50) supported by an armature (60), the armature (60) being supported by the undercarriage (110) and fixed in relation to the undercarriage (110), the traverser (50) being configured to move the sleepers from at least one receiving zone (Z1, Z2) to at least one conveying platform (P2).

An installation for cleaning ballast of a track includes a plurality of vehicles having machine frames supported on on-track undercarriages. Two shoulder clearing chains, positioned opposite one another relative to a transverse direction of the track, take up ballast located in a shoulder area adjoining sleeper ends, an endless clearing chain follows the shoulder clearing chains relative to a working direction of the installation and is to be guided around the track for taking up ballast underneath the track. A screening installation, conveying devices for transporting ballast, and a ballast introduction device are also provided. A first conveying device transporting ballast to the screening installation is associated with the shoulder clearing chains. A second conveying device transporting ballast to a processing unit is associated with the endless clearing chain. A third conveying device transporting ballast to the screening installation is associated with the processing unit.

A system (10) for sieving ballast comprises a first sieve (26) and a second sieve (28) which is located behind the first sieve (26) in a first direction (100). A discharge collection conveyor (32.1) is located directly under a first discarded ballast outlet (42) of the first sieve (26) in order to collect a flow of discarded ballast which comes from the first sieve (26) and to convey it in a second direction (200) counter to the first direction (100). A rerouting collection conveyor directly collects the flow being discharged from a clean ballast outlet of the second sieve in order to convey it in the first direction (100). The rerouting collection conveyor extends under the first sieve (26) at a lower height than the discharge collection conveyor.
