KEY: RPM = revenue passenger-mile.
NOTES: Amtrak data are not available prior to 1993. Revenue includes revenue from concessions and other passenger services in addition to passenger fares. A revenue passenger-mile is the number of revenue passengers multiplied by the number of miles traveled by each passenger.
Current dollar amounts were converted to chained 2000 dollars by the Bureau of Transportation Statistics to eliminate the effects of inflation over time.
