The National Transportation Safety Board (NTSB) said this week that it has released the accident docket on the Amtrak passenger-train derailment that happened on May 12 last year in Philadelphia.
The NTSB also released over 2,000 pages of documentation tied to the derailment.
Amtrak passenger train No. 188 derailed after attempting to round a curve traveling at 106 mph, where the speed limit is 50 mph. Eight passengers died, and over 200 others were hospitalized.
The docket contains only factual data on the derailment and doesn't draw any conclusions on what happened. Opening the docket signals that officials are shifting from fact finding to analyzing what happened.
The documents include letters, interview transcripts, factual reports and photos, and the NTSB said it is important that the public not use the docket to draw any conclusions as to how or why the derailment happened.
The NTSB will publish its analysis, recommendations and other findings later in the investigation.
