Notice of approval of modification.
Summary
FRA is issuing this notice to explain its rationale for granting a modification to the previously-approved BNSF Railway Company (BNSF) Test Program designed to test track inspection technologies (i.e., an autonomous track geometry measurement system) and new operational approaches to track inspections. The previously-approved Test Program included a limited, temporary suspension of a substantive FRA rule that is necessary to facilitate the conduct of the Test Program.
