IOWA RAILROAD TRACK GEOMETRY RATINGS - JULY 1978

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 62.2% of all track in good condition, 37.6% in fair condition, and 0.2% in critical condition.
