Abstract
A mobile arrangement for rehabilitating a ballast bed by installing a protective layer between a subgrade and layer of ballast at a construction site of the track includes an excavation unit for continuously removing old ballast from the ballast bed to expose the subgrade and a rock crusher unit which receives at least a portion of withdrawn old ballast for comminution thereof. Comminuted old ballast is then laid over the exposed subgrade for forming at least part of the protective layer.
