ABSTRACT OF THE DISCLOSURE A mobile ballast cleaning machine comprises a frame mounted on two undercarriages for mobility along a track supported on the ballast resting on a subgrade. A bal- last excavator is mounted on the frame between the track to expose the subgrade and a ballast screen is arranged on the frame to receive the removed ballast from the bal- last excavator and to discharge cleaned ballast and waste. Conveyor bands carry away the waste and redistribute the cleaned ballast, the ballast redistributing conveyor band having a discharge end and an exposed subgrade zone being defined between the ballast excavator and the discharge end for laying a succession of rigid foam plates on the exposed subgrade. Apparatus for handling the rigid foam plates in- cludes a plate receiving and transfer station, an elongated plate conveying path extending from the station to the ex- posed subgrade zone for conveying successive ones of the plates in a direction substantially parallel to the track, and a plate turning and laying mechanism in this zone re- ceiving successive rigid foam plates from the conveying path, for turning the plates and for laying the turned plates suc- cessively in the zone under the track in a position extend- ing transversely to the track.
