Abstract
This disclosure relates to a railway trackway having a pair of running rails and including a plurality of vibrational dampening mechanisms disposed at selected intervals along the running rails of the trackway. 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.
