This page provides information about radio communication channels and frequencies used by Amtrak on the Sunset Limited Route. (Note: many of these frequencies may be inaccurate, as the Union Pacific Railroad has restructed and changed many of their frequencies over the last few years, since the SP merger. If you know of any errors on this or any other frequency page, please e-mail matt@trainweb.com. Thank you.)
