Monthly data, not seasonally adjusted
The National Railroad Passenger Corporation (Amtrak) officially began service in May 1971. Amtrak serves more than 500 stations in 46 states and operates over a network of more than 21,000 route miles. Ridership is highly seasonal, with July and August being the highest volume months. In 2000, Amtrak introduced high-speed rail service in the northeast U.S., which helped increase ridership.
|Percent change from same month previous year||+ 3.3%||- 4.0%|
NOTES: The current value is compared to the value from the same period in the previous year to account for seasonality.
Starting with October 2013, Amtrak began counting actual lifted ridership for multi-ride tickets, rather than estimating multi-ride ridership. One result is that adjusted ridership for earlier periods is generally two to three percent lower than under the new standard. More information is available in Amtrak's Monthly Performance Reports, available at http://www.amtrak.com.
