A machine for cleaning debris from railway roadbeds, particularly from between rails of a single track and the space between tracks in railroad yards, comprises an articulated tractor and scraper-loader, each preferably having only two wheels. The scraper-loader has a scraper blade which extends transversely to the track when the machine is in use and a notch which loosely fits over a rail. The blade has wings extending oppositely from the notch. One of the wings has a length which is substantially equal to, but no greater than, the distance between the rails of a track, and the other has a length equal to at least one-half of that distance. The blade has a shoe which overlies the notch and which rides on the surface of a rail to establish the depth of the blade relative to the rails. The shoe is adjustably mounted on the blade so that such depth can be varied in order to clean between the rails of tracks which have rails of different heigths above their ties. The scraper-loader has a storage compartment into which the debris is fed so that it can be re-used to fill low places in the roadbed or carried to a disposal site.
