Amtrak IG Audit – Safety and Security – Progress Made Implementing Positive Train Control, but Significant Challenges Remain, 06/19/2015. OIG-A-2015-013

“The tragic derailment of Amtrak Train 188 in Philadelphia on May 12, 2015, continues to raise many questions, ranging from causation to safety systems that could have mitigated the excessive speed. In view of the current interest in the company’s progress implementing PTC, we are issuing this interim report on the results of our work to date. Our reporting objective is to provide a point in time assessment of the company’s progress implementing its FRA-approved plan, with a specific emphasis on the Northeast Corridor (NEC). We also generally discuss implementation progress on routes off the NEC and overall program management issues. We are continuing our work and plan to issue a final report at a later date.”
