Energy Intensity of Amtrak Services

(Loss-adjusted conversion factors)

Dataset Excel: 
Notes: 

Energy intensity (Btu/revenue passenger-mile) is calculated by the source and may differ from direct calculations.

The heat equivalent factors used in Btu conversion are: 

  Diesel = 138,700 Btu/gallon.

  Electric = 10,399 Btu/kWh. The electric conversion factor takes into account losses associated with the generation, transmission and distribution of electricity, and thus it is more than three times the value of the factor that is used in table 4-26.

Description: 

KEY:  Btu = British thermal unit; kWh = kilowatt hour; R = revised.

a Revenue passenger-miles data prior to 2001 are fiscal year data; 2001 data and more recent data are calendar year data.

b Includes electric power generation and distribution losses.

cElectric usage and diesel usage data are calendar year data.
