"Method for calculating a skidding or lifting of a railway track during a tamping-skidding-lifting by a tamper, suitable tamper" Method for calculating a skidding RA or a lifting RLA of a track railway by a tamping machine (1) comprising a tamping-skidding-lifting wagon (2) at the front and a downstream measuring wagon (3) at the rear, a programmable computer calculating RA from measurements of reference track-line deviations and deflection determinations defined by bases, the tamping-shifting-lifting wagon (2) defining a first base AD and allowing the computer to determine during shifting an arrow Fc at point C of the base AD from deviation measurements at points A, C and D, the measuring wagon (3) defining a second base A'D 'and allowing the computer to determine following the shifting an arrow Fc' at point C 'of the base A'D 'from deviation measurements at points A', C 'and D', and calculate RA using the determinations of the arrows es Fc and Fc ’at points C and C’ while the tamper is advancing (1). In particular, we perform a transposition of arrows FC "base A'D" in arrow FCat at point C of base AD. Figure 1
