According to a headline I saw on the Wall Street Journal, BNSF is going to test using natural gas to power its locomotives. I will see if I can find a link.
Mr Moorman called LNG conversion “an extraordinarily interesting opportunity”. But he queried whether gas-powered locomotives would generate the power of diesels.
Mr Koraleski acknowledged it was undoubtedly possible to run a locomotive on natural gas, but he added: “The question is, can you do it economically, can you do it safely and can you do it on a consistently reliable basis?”
