UP spokesman Mark Davis told the Topeka Capital Journal the 135-car train was headed from Wyoming to Kentucky when the cars derailed west of Perry.

Crews were still working to determine the cause of the incident, which occurred at 11.40am local time Sunday.

One of the company’s two main tracks in the area was closed as a precaution, though Davis told the paper no damage was sustained to the closed portion.

The line was given the go-ahead to reopen at about 2pm on Sunday afternoon.

According to Davis, another 500ft area that did sustain damage was replaced late Sunday and opened for business at about 1am Monday morning.

In related UP news, the Associated Press reported the company was set to hold a community meeting in Illinois to discuss the July 4 coal train derailment that killed two.

Representatives from the Federal Railroad Administration will attend the gathering, along with the Illinois Commerce Commission and the Illinois Department of Transportation.

The group will discuss a 2009 derailment in the same proximity as the most recent incident and will also share preliminary findings and plans for temporary repairs and a permanent bridge replacement following this month’s fatal derailment.

The public will also have an opportunity to address UP during a question-and-answer session.

UP officials have reportedly pointed to the intense heat as a contributor to the incident, claiming in its preliminary findings that the temperatures caused a track defect.

Burton and Zorine Lindner were killed in their car, which was sitting under a bridge when part of a 138-car coal train derailed and fell from the overpass.

The weight of the train, which was going from Wyoming to Wisconsin, brought the bridge down with it.

The victims’ family members have reportedly filed a wrongful death lawsuit against UP.
