Willie,
Is that you ?
Seriously, CSX’s numbers are lacking one essential dimension - the pounds being carried.
2009:
Schedule 750, Fuel consumed (freight + switching) = 446,999,921 gallons
Schedule 755, line 110, Revenue Ton-Miles = 209,248,946,000 RTM
RTM per gallon = (209,248,946,000 RTM / 446,999,921 gals) = 468 RTM/gal
