One of the trains involved in the June 28 head-on collision between two BNSF intermodal trains outside of Panhandle, Texas passed a red signal before the accident.
This comes from the National Transportation Safety Board's (NTSB) preliminary report of the incident, which was published July 13.
The report reads, "The signal system was lined to route the westbound train into the Panhandle control point siding at milepost 526.1 while holding the eastbound train on the main track before the east end of the siding.
"Preliminary review of signal event recorder data and tests of the signal system indicate the last signal the eastbound train passed before the collision was a stop (red) signal. The previous signal the eastbound train passed was an approach (yellow) signal.
"A preliminary review of locomotive event recorder data revealed that the eastbound train was traveling about 62 mph when it went by the approach signal at the west end of the Panhandle siding and about 65 mph when it went by the stop signal at the east end of the Panhandle siding.
"Investigators completed sight distance tests of the signal system for the operation of both trains into the collision point, and the results are being analyzed. Investigators also shipped event and video recorders to the NTSB recorders laboratory in Washington, D.C., for further analysis."
Weather does not appear to be a factor as it was clear and 74 degrees at the time of the accident. The collision caused the derailment of the locomotives and several cars from both trains and a significant fire occurred. Three crew members died in the accident—the engineer and conductor on the eastbound train and the conductor on the westbound train. The engineer of the westbound train jumped from the train before impact and survived with injuries.
Train movements in the area of the accident are governed by signal indications of a traffic control system. A positive train control system is scheduled to be implemented by the BNSF in this area by the end of 2016. The BNSF estimated damages of $16 million.
NTSB said the investigation is ongoing and it will supplement or correct information during the course of its investigation. Full report HERE.
