From the Wall Street Journal on Tuesday:
Top U.S. railroad BNSF Railway Co, one of the largest users of diesel fuel in the United States, plans to test using natural gas to power its locomotives this year.
If successful, the experiment could weaken oil's dominance as a transportation fuel and provide a new outlet for the glut of cheap natural gas in North America, the paper said.
"This could be a transformational event for our railroad," BNSF Chief Executive Matt Rose told the Journal.
BNSF is the second-biggest user of diesel in the United States after the U.S. Navy.
