RAILWAY NOISE. NOISE ANNOYANCE FROM BRAKING AND NEGOTIATING SHARP CURVES; FUNDAMENTAL CONSIDERATIONS AND FIRST TEST RESULTS
This report describes chiefly the general principles for reducing noise annoyance, when negotiating sharp curves, by applying coatings to wheels and rails. A track installation with a 90 m curve and different types of vibration damped and normal rails is described; screech noise generated during the passage of four wagons, with and without damped wheelsets, was studied. A further section gives first results of measurements taken to investigate the influence due to the material composition of cast-iron brake blocks on noise generation during braking.
