Definitions

  • Numerous machines for repairing railroad tracks and chiefly for clearing away the ballast provide simultaneously said clearing and the renewal of the railroad and it is consequently essential to set the various implements, chiefly the levelling blade and the ramming means which ensure the levelling of the new railroad bed, at a location which is perfectly defined in relationship with a reference surface, which is generally constituted by the prior bed, before its clearing and over which the front axle or the front section of the machine is caused to progress.
