ABSTRACT:
A mobile track leveling machine comprises a pneumatic arrangement for introducing additional ballast into a gap between a track bed and a lifted track, which includes a storage container for the ballast, a vertically adjustable pipe arranged to receive ballast from the storage container and to be immersed in the track bed alongside a longitudinal edge of a respective track tie, the pipe having a tapered end for ready penetration into the track bed and a flattened side defining an outlet for the additional ballast facing the longitudinal tie edge. Compressed air is delivered into the pipe for moving the additional ballast therethrough and out of the outlet. A power drive vertically adjusts the pipe, a stop is arranged on the pipe for engagement with the lifted track to limit the immersion depth thereof, and a power-driven metering device is arranged between the storage container and the pipe for delivering a metered amount of the additional ballast from the container to the pipe, the additional ballast amount being metered by the device in response to the lifting stroke to fill the gap between the track bed and the lifted tie.
