Notice of approval.
Summary
FRA is issuing this notice to explain its rationale for approving a Norfolk Southern Railway Company (NS) petition for a Test Program designed to test track inspection technologies (i.e., an autonomous locomotive-mounted geometry measurement system and an automated optical system) and new operational approaches to track inspections and its rationale for granting a limited, temporary suspension of a substantive FRA rule that is necessary to facilitate the conduct of the Test Program.
