ABSTRACT OF THE DISCLOSURE A mobile ballast cleaning machine mounted on a track for movement in an operating direction incorporates apparatus for continuously measuring parameters indicating the track position and any changes therein with respect to a reference system caused by ballast excavation, and for recording the measured parameters. This apparatus comprises hydrostatic level measuring devices mounted in the region of the front and rear undercarriages at the laterally extending sides of the machine frame, two further hydrostatic level measuring devices transversely spaced apart and mounted on the lateral courses near the laterally outermost regions of the endless ballast excavating chain, an additional hydrostatic level measuring device mounted in the region of a track sensing element arranged on the frame forwardly of the front undercarriage, and a conduit connected to the hydrostatic level measuring devices for delivering a liquid thereto. The devices comprise emitters of electrical output signals corresponding to the measured parameters whereby the apparatus is capable of providing a reference base for the parameters superelevation, inclination and lowering of the track level. 0147E
