FIELD: process engineering.
SUBSTANCE: prior to starting the works, base penetration of tamping pick is set with the help of control unit setting device to calculate penetration at every point of repaired track, depending upon rail height and tie sizes. Track section to be straightened can consist of two and more sections with different structural characteristics, for example, size "B" and "B1" of rails 3, 4. Then, in changing from one track to another, said base magnitude is varied by tamping pick penetration into ballast. Said base magnitude of tamping pick penetration in ballast may be preset and switched automatically by track straightening programme.
EFFECT: stable density of ballast.
