CUSHIONED TRACK

Accomplishments throughout the years in the area of track cushioning provided by Butyl Rubber pads are summarized. Advantages in the use of track vibration damping are given as reduction of wear and tear imposed on the track for higher speeds and heavier tonnage. Other considerations include the reduction of rough riding, unsafe pumping of the track, and damage to equipment, ties, ballast, and subgrade of the rail. The relation between maintenance costs for track using the damping and those without cushioning is discussed. Extensive use of Butyl pads in curved rail sections and crossings is stressed as a major improvement in the service life of the track structure.
