For some newer avenues that natural gas might find itself headed down, look no further than railway and marine transportation. Already, there has been public buy-in from some of the biggest companies in the United States. Earlier this year, Warren Buffett's Berkshire Hathaway (NYSE:BRK-A) made it well known that its portfolio company, BNSF, would begin testing the use of liquified natural gas as a substitute for diesel fuel in its locomotives. This could have huge positive implications for the natural gas industry and equally negative effects on the diesel fuel sector.

For more information on these two sectors, as well as Wesport Innovations' (NASDAQ: WPRT) foray into the use of natural gas in marine engines, tune in to the following video, where contributor Tyler Crowe teams up with analysts Joel South and Taylor Muckerman to give you all of the details.
