NOTES

BTS is developing more comprehensive and reliable estimates of tonne-kilometers for the air, truck, rail, water, and pipeline modes than are presented in table 1-46a. These improved estimates are not comparable to data in table 1-46a. Improved estimates for 1960-1989, which will allow more comprehensive and reliable data for the entire period from 1960 to present, are still under development and will be reported when they are completed.

Numbers may not add to totals due to rounding.

1.459972 tonne-kilometers = 1 ton mile.
