We have developed a new method for repairing railway track irregulari-
ties with heavy mechanical machines.
Levelling and lining operations in
these machines are based on the so called 3-point measurement system with
asymmetric chord spacing.
To repair effectively track irregularities over the
wide-range of wavelength, an absolute reference frame method is excellent
but it requires the measurement of the actual track geometry before the
In our new method such an extra measurement is not required.
the waveform restored or reconstructed by the inverse operation from the
usual versine data is used.
But a restoration is only able to be carried out
in the limited range of wavelength and so not equal to the actual track ge-
Therefore the effectiveness...
