Amtrak is using automated maritime telecom system spectrum, the bureau said. The order requires Amtrak to protect nearby broadcast stations, using channels 10 and 13, from interference.

Some have said a deadly crash outside of Philadelphia could have been prevented had PTC been deployed on the section of track where the accident occurred (see 1506100037). Congress required Amtrak, and many commuter and freight railroads, to deploy interoperable PTC systems as part of the Rail Safety Improvement Act of 2008.
