A computer system and computer implemented method of predicting track quality of a section of railway track is described. The method accesses sets of track geometry quality data values that comprise data channels. Standard deviation values are calculated for the channels channel and then degradation rates based on a difference value between two of the standard deviation values over a time period are calculated. The method identifies if any of the degradation rates is a tamped degradation rate indicative an occurrence of tamping of the section of railway track. Then a quality estimate for the section of railway track is determined. This quality estimate is based on at least two selected said calculated degradation rates and a spaced time interval between dates associated with the selected calculated degradation rates.
