IOWA RAILROAD TRACK GEOMETRY RATINGS

Comprehensive test results from the use of a track geometry car by the Iowa Department of Transportation are given, along with the explanation of the method of rating track. The track geometry rating is calculated for each one-mile segment of track in the state. The final rating is a composite of separate calculations for track gage and cross level, with equal weight being given each. Details for rating of 6,550 miles of Iowa track are given; an additional 960 miles have not been rated for various reasons. Inspectors rated 58.4 percent of all track in good condition, 34.1 percent in fair condition and 7.5 percent in critical condition.
