Natural gas eyed as fuel for trains https://www.sfgate.com/business/article/Natural-gas-eyed-as-fuel-for-trains-3948140.php
"Railroad companies seem to believe natural gas prices are going to remain low and stable because of booming production of gas from shale plays, giving it a consistent price edge over diesel - which now sells for $1 to $2 more per gallon than an equivalent amount of natural gas.
With industry leaders Union Pacific and privately held BNSF Railway each consuming around 1 billion gallons of diesel annually, even a difference of a few cents per gallon can mean tens of millions of dollars in savings"
i wonder what they mean by an equivalent amount.- does not LPG have a more substantial cost advantage than that? ( vs diesel, BTU wise)
