An update to the NTSB docket involving the investigation of the February 3 train derailment in East Palestine reveals the conversation taking place within the train between the conductor, the engineer, and a conductor trainee on board, and when they knew of an issue with Norfolk Southern 32N.

The conversation was captured by the onboard image recorder.

The audio shows a critical alert was first received at 8:53 pm, followed by the engineer on board saying, "All we go."

The report shows the initial confusion on what caused the alarm from the crew and the speculation of what triggered the emergency braking on the train, including the more than 6 minutes before the trainee said, "We went apart— we went apart."

According to the report, the train was traveling at approximately 21 mph as it headed into East Palestine at 8:50 pm. The locomotive passed over the alerting hot box detector in East Palestine at approximately 8:52:47 pm, and the critical alarm sounded at 8:53:15 pm. The train slowly decelerated over the next minute, followed by several alarms sounding in the cab at 8:54:22 pm.

The train then quickly decelerated, stopping at 8:55:04 pm, but it was too late; the train had already derailed.

Read the actual transcript as the crew discussed the issues they saw and communicated with dispatch. The NTSB Vehicle Recorder Division received a total of 63 video files from five camera sources, with three of these sources onboard the lead locomotive from which this transcript was created.

The conversation starts off with the conductor commenting, "They still have us at (Conway) at midnight.”

At times are eastern, p.m., and the conversation is transcribed as heard from the recordings. 'Undetermined voice' means not being able to determine who was speaking.
