This photo from Sept. 14, 2013, which was provided by General Electric, shows an experimental natural gas locomotive in Erie, Pennsylvania. The diesel locomotives that became freight railroads’ workhorse after World War II could be replaced in the next few years by units like this that burn a mix of natural gas and diesel. The switch could likely reduce fuel costs and pollution significantly while allowing railroads to take advantage of abundant domestic supplies of natural gas. But many questions about using natural gas locomotives remain unanswered, and those could easily derail the idea. (AP Photo/General Electric, Mark Fainstein)
