Norfolk Southern Eliminated Key Maintenance Role in Derailment Region, Union Says
One union of rail workers has questioned declining maintenance standards following the Feb. 3 Norfolk Southern derailment in East Palestine, Ohio, which forced the evacuation of the 5,000-person town earlier this month.
A device that can play a role in preventing derailments is the wayside hot-box detector. It uses infrared sensors to detect bearings, axles or other components of a rail car that are overheating, then uses radio signals to flag rail crews of any overheated components.
The rail car that initiated the derailment had an overheated wheel bearing, according to a Tuesday report from the National Transportation Safety Board. The NTSB is still investigating the cause of the derailment and will publish a preliminary report in two weeks.
Wayside hot-box detectors — also called “hot boxes” — are typically placed every 25 miles along a railroad, according to a Federal Railroad Administration (FRA) report. Their use has contributed to a 59% decrease in train accidents caused by axle- and bearing-related factors since 1990, according to a 2017 Association of American Railroads study.
Declining head counts have led to these mechanisms receiving less preventative maintenance, according to an official from the Brotherhood of Railroad Signalmen union.
The FRA has no regulations requiring the use or maintenance of hot boxes.
A hot box in East Palestine notified the crew moments before the train derailed, according to the NTSB’s report.
It’s unclear if any hot box prior to East Palestine notified crews. A surveillance video shared on Facebook from an industrial facility in Salem, Ohio, about 20 miles from East Palestine, suggests the train’s axle was already on fire.
Norfolk Southern did not respond to a request for comment, and the FRA declined to comment on the record.
