      <title>NONFRICTION BRAKING METHODS FOR RAILWAY VEHICLES</title>
      <link>https://trid.trb.org/View/10931</link>
      <description><![CDATA[Performance potential and approximate cost estimates are presented for three nonfriction braking systems: air retarder, hydraulic retarder, and aerodynamic braking.  It is shown that the air and the hydraulic retarders have potential to develop full braking deceleration in a speed range from 250 to 25 mph.  Because of the air retarder's potential advantages in system weight, simplicity and cost, prototype development of the retarder is indicated. Aerodynamic braking deceleration is highly dependent on the cumulative effect of longitudinally spaced braking surfaces.  Further wind tunnel testing is required for complete evaluation.]]></description>
