MOBILE TRACK RENEWAL MACHINE ABSTRACT OF THE DISCLOSURE A mobile machine for continuously renewing a track by replacing the rails and ties of the existing track by new rails and ties has an elongated, two-part, bridge-like machine frame supported on the track by a front and a rear undercarriage. The facing ends of the machine frame parts are pivotally coupled together at lower ends thereof, and hydraulic pivoting and blocking drives interconnect these facing ends and are effective to spread the facing machine frame part ends apart at upper ends thereof in a horizontal direction whereby the lower ends of the facing machine frame part ends are raised in a vertical direction, and the raised facing machine frame part ends are blocked in their raised position. An intermediate undercarriage supports the facing machine frame part ends on the track and is raised off the track with the lower ends of the facing machine frame part ends. The machine frame carries devices for lifting and spreading the old rails off the ballast bed rails, for lifting the old ties off the ballast bed whereby residual mounts of ballast remain on the ballast bed between areas thereof where the lifted ties were embedded in the ballast bed, a ballast excavating and planing chain arranged to excavate the residual ballast mounts and to smooth the ballast bed, devices for laying the new ties on the smooth ballast bed and for spreading and laying the new rails on the new ties. A ballast conveyor is mounted on the rear machine frame part for receiving the excavated ballast from the chain.
