1. A method comprising:
performing correction work providing track position improvement using a track-movable track-tamping machine with a three-point work measurement system having three measurement carriages and a cord stretched therebetween, a tamping unit, and a lifting and straightening unit for tracks; and
recording an actual position of the track after the correction work of the track-tamping machine using the measurement system;
calculating using a computer a difference between a predetermined desired track position and the actual position recorded by the measurement system, as a residual error; and
continuously adjusting a detected position of a rear cord end on a rear measurement carriage of the measurement carriages of the track-tamping machine of the three-point work measurement system so that an adjusted detected position the rear cord end on the rear measurement carriage is guided on the desired track position; and
calculating with the computer a correction of a position the track to a desired track position using the adjusted detected position of the rear cord end in the three-point measurement system; and
correcting the position of the track with the track-movable track-tamping machine so as to place said track into a position defined by said calculated correction.
