Each of the vibrational dampening mechanisms includes a support assembly and a biased wheel engaging assembly for engaging the passing wheels of the railway vehicles for dissipating the vibrational energy imparted to the vehicle wheels thereby preventing the production of wheel squealing or screeching noises.
