Notice of extension of comment period.
Summary
On April 28, 2025, FRA published a notice of availability and request for comments about the request for amendment (RFA) that the National Railroad Passenger Corporation (Amtrak) submitted on April 16, 2025. Amtrak's RFA requests authorization to temporarily disable one of its FRA-certified positive train control (PTC) systems for a period of one to two hours in support of the installation and testing of a new Back Office Subsystem environment upgrade. FRA is publishing this notice to extend the comment period, which would otherwise end on May 19, 2025, to May 30, 2025, due to a technical docket issue that occurred at the time of publication of the first notice.
