a Amtrak began operations in 1971. Data are reported for fiscal years.
NOTES
Average length of haul for freight is calculated by dividing ton-miles by estimates of tonnage from the various data sources. The calculation of average length of haul for passenger trips varies by mode: for air carrier it is calculated by dividing revenue passenger-miles by revenue passenger enplanements; for commuter rail and Amtrak it is calculated by dividing passenger-miles by number of passengers.
Eno Transportation Foundation has discontinued some data series years prior to 1990.
