​ On September 17, 2023, about 3:24 a.m. local time, a member of a CSX Transportation (CSX) mechanical department crew (the accident carman) was struck and killed by a pair of remote-control locomotives during switching operations in a remote-control zone on the Walbridge Yard lead track in Walbridge, Ohio. At the time of the accident, the accident carman was walking across multiple tracks to line and lock a switch to prepare for railcar inspections. As the accident carman began crossing the lead track to access the switch, he was struck by the locomotives.

We determined that the probable cause of the CSX employee fatality that occurred on September 17, 2023, was the failure of the accident carman to comply with the CSX operating rule that required an employee to stop and look both ways before fouling a track. Contributing to this accident was the failure of the accident carman to conduct a thorough job briefing as prescribed by CSX operating rules before the accident. ​​
