A Study on the Evaluation of Track Support Stiffness on the Various Track Type in Urban Transit [PDF]
Journal of the Korean Society for Railway, 2011 Track support stiffness which affected track maintenance and riding comfort had a big effect on the track and train. Also, track support stiffness of the track design which was based on theory differs from track support stiffness of the track generated on the field.

Evaluating railway track support stiffness from trackside measurements in the absence of wheel load data [PDF]
Canadian Geotechnical Journal, 2016 It is generally accepted that track support stiffness is a major factor controlling rates of track geometry deterioration, particularly where the track support stiffness changes abruptly. There is, therefore, considerable potential benefit in being able to quantify and detect changes in the track support stiffness.

Quantification of Dynamic Track Stiffness Using Machine Learning
IEEE Access, 2022 Railway track stiffness is an essential factor influencing the track conditions and long-term deterioration. However, the traditional ways to measure the track stiffness are based on inverse computations using multi-body simulations and/or finite element
