Urgent Safety Recommendation

摘要

The National Transportation Safety Board is an independent Federal agency charged by Congress with investigating transportation accidents, determining their probable cause, and making recommendations to prevent similar accidents from occurring. The urgent safety recommendation in this letter is derived from the Safety Board's investigation of the two derailments that occurred on the Northeast Illinois Regional Commuter Railroad Corporation (Metra) property at West 47th Street in Chicago, Illinois; one on October 12, 2003, and the most recent on September 17, 2005. The Board would appreciate a response from you within 30 days addressing the actions you have taken or intend to take to implement our recommendation.
