Railroad travelers can compare rail rates using the AmSnag Web service. While Amtrak provides Web users with timetables, train schedules and ticketing information, AmSnag automates the process of comparing rail rates throughout the United States.
Travelers who wish to use AmSnag to compare rail rates between two U.S. train stations must use Amtrak's three-letter codes to refer to the intended origins and destinations. Examples of Amtrak codes include the code NYP for New York Penn Station and LAX for Los Angeles Grand Central Station; Amtrak provides a comprehensive list of codes through the Find a Station tab on its official website.
To use AmSnag, simply enter your intended origin and destination station codes, a date of departure and a range of days for which you would like rail information. The AmSnag engine automatically compares rail rates within the range of dates specified and produces a list that begins with the lowest available fare.
AmSnag users who have successfully compared rail rates and wish to purchase tickets must do so on Amtrak's website, as of 2015. Anyone can purchase tickets from Amtrak online, and tickets are deliverable by post or email, or from the Quik Trak self-service machines available to the public in every Amtrak train station.
