FIELD: railway transport.
SUBSTANCE: engineering machine comprises frame supported by running bogies and ballast compaction unit up/down drive. Machine frame incorporates supports to interact with rails that are furnished with rail grippers with drive to press the latter down against rails. Machine comprises at least one beam and at least one lever. Said beam is arranged across machine frame and is rigidly or pivot-jointed to ballast compaction unit frame elements. Aforesaid lever is pivoted on machine frame to be turned by the drive. Lever end is pivoted on the beam to allow it move across machine frame.
EFFECT: expanded performances, that is, machine straightens rack, compacts ballast and elevate track.
