5 ANALYSIS OF MAJOR DEFICIENCIES
Below is a description of the major track deficiencies, along with contributing factors, where appropriate.
In addition, these deficiencies are referenced to the remedial actions (as described in chapter 4) that are
designed to correct them.
Inadequate Lateral and Longitudinal Track Stability
The track at the installation has, at best, a surface layer of crushed rock ballast. Most stretches have a
low density mix of fine crushed volcanic material and earth filling in the spaces between and around the
ties. This material does not provide adequate lateral or longitudinal track support. And as a result, track
alignment is generally fair or poor, and many ties have shifted position and become skewed (not
perpendicular to the rails).
To both restore and keep proper track line and surface and maintain proper tie position, a sufficient
amount of good quality ballast material must be added to the track. In addition, anchors must be correctly
re-applied and added where needed. Remedial Actions 2,6,8,9,12, and 13 (as listed on page 16) are
designed to establish adequate lateral and longitudinal track stability.
About 25 percent of the asphalt crossings are in poor condition, and likewise, so is the track in them; ties
have deteriorated, track support is mushy, and joints have loosened - in some cases allowing track gage
to widen to an unsafe distance.
