Non linearity is the complicated problem for the dynamic modeling parameters solutions. The frequency and damping along with wavelength and particularly bogie wavelength are the fundamental terms to analyze the proper running of the railway vehicle wheelset on track. In this paper the brief dynamics of railway wheel contact is discussed and eigen values are generated and simulated to analyze difference depending upon both for higher and lower creep coefficient. Thus damping and frequency of wheelset is also simulated with relation to eigen values to observe their attitude. The wavelength is also compared with frequency and velocity of vehicle based upon both higher and lower creep coefficients along with eigen values. With the help of these wavelengths, a bogie wavelength relationship is developed and observed to detect the performance of railway vehicle wheelset.
