A lack of markers warning of a close-clearance situation was the probable cause of a fatal accident involving a BNSF Railway conductor in La Mirada, Calif., on March 3, 2021, the National Transportation Safety Board said in a final accident report issued late last week.
The conductor was killed during a shoving move shortly after midnight at Buena Park Yard while riding the side ladder of a boxcar, when he became pinned between that car and a locomotive parked on an adjacent track [see “Digest: NTSB releases preliminary report …,” Trains News Wire, April 2, 2021].
