3)
Anchors not replaced after tie installation, or applied to only one rail (one side of the tie).
4)
Track on grades. Portions of the track are on grades steep enough to encourage longitudinal rail
movement, and thus also, tie movement.
5)
Spikes driven in the slots in angle bar type joint bars. This is no longer considered good practice.
As joints are usually staggered, rarely does a tie ever have a joint on both rails. Driving spikes
into the joint bar base slots will then have the same effect as anchoring only one side of a tie.
6)
Ties with incorrect spiking pattern, present in some of the older ties. (While this incorrect pattern
does not actually cause tie skewing, it does encourage it).
7)
Some ties appeared to have been installed crooked.
Remedial Action 7 provides for repositioning skewed and misspaced ties, and Remedial Action 10 will
help prevent future tie movement.
Loose or Missing Track Fastenings
Numerous rail joints have loose or missing bolts, and several joints (at least 12 noted during the
inspection) have both bolts in one rail missing. Remedial Action 8 calls for tightening all joints and
replacing defective bolts and joint bars.
Vegetation In or Near the Track
Scattered locations along primary routes and loading sidings have thick brush growing close to the track,
and in some cases, in the ballast section. This vegetation must be removed before any track work can be
performed.
