We are honored by the opportunity DART has given us to develop the new station infrastructure that will support one of America's largest CNG transit bus fleets." Based in Dallas, Texas, DART deploys buses on 135 fixed and express routes, serving the communities of Addison, Carrollton, Cockrell Hill, Dallas, Farmers Branch, Garland, Glenn Heights, Highland Park, Irving, Richardson, Rowlett, Plano and University Park, Texas. In fiscal year 2010, passenger boardings of DART buses totaled more than 38 million. Costing less than diesel, natural gas fuel produces up to 23%-percent lower greenhouse gas emissions in medium to heavy-duty vehicles. US Department of Energy reports estimate that 98% of the natural gas consumed in the US is sourced in the US and Canada. Using natural gas fuel can prevent tons of emissions from entering the atmosphere throughout the operating life of a typical bus fleet, while also lowering a transit agency's operating costs significantly.
