Abstract

A track renewal machine includes an mobile machine frame having a ballast chute on a machine end. A tie laying device for laying new ties and a tie lifting device for picking up old ties are mounted on the machine frame, and a ballast clearing device for taking up ballast is arranged following the tie lifting device in an operating direction. A first conveyor transports ballast to the machine end and is disposed behind the ballast clearing device, and a ballast planing device is mounted on the machine frame immediately ahead of the tie laying device. A second conveyor extends on the machine frame in longitudinal direction thereof and has a receiving end positioned at the machine end and a discharge end arranged above the ballast planing apparatus. Cleaned ballast can thus be received from either a screening car or from a storage wagon coupled to the machine.
