Major freight railroads are rushing railcar inspections, reinforcing known safety concerns raised by unions for years, but at a House hearing Tuesday they'll present new evidence from federal inspectors that railcar checks are routinely less than two minutes per car. The unions have sounded the alarm often in recent years as the major railroads all adopted versions of the lean Precision Scheduled Railroading operating model and collectively cut roughly one-third of all their workers. Labor groups like the Transportation Communications Union, which represents the expert carmen who are supposed to inspect railcars, have said all the cuts have led to rushed inspections that miss problems and prompted railroads to rely on train crews too often to do limited inspections.

The disastrous Norfolk Southern derailment last year in East Palestine, Ohio, that prompted Tuesday's hearing was caused by an overheating bearing that wasn't caught in time by trackside sensors. The National Transportation Safety Board didn't speculate in its final report released last month whether an inspection in a railyard might have caught the failed bearing, but it did point out that the railroad never inspected the car after it picked it up in St. Louis even though it crossed through several railyards before the crash.

And more than 25% of the cars on that train had defects despite being inspected beforehand. The TCU union's National Legislative Director David Arouca says inspections are happening less oft.
