The California Northern Railroad, which operates in the Napa Valley, has converted its entire fleet to environmentally friendly locomotives with the addition of four new N-ViroMotive Gen-Set locomotives.
The purchase of the ultra-low emitting, low-noise, fuel-efficient locomotives from National Railway Equipment Company was made possible by California’s Carl Moyer Memorial Air Quality Standards Attainment Program, which covered 85 percent of the cost.
The new locomotives, which will be in service by mid-January, are certified by the Environmental Protection Agency and meet its three-tier emission standard.
Compared to previous locomotive emissions, they reduce nitrous-oxide and particulate-matter emissions by 85 to 90 percent, providing a substantial reduction in CFNR’s carbon footprint.
“Now that all five of California Northern Railroad’s locomotives are ultra-low emitting and more fuel-efficient, having an average fuel savings of 20 to 30 percent, we are able to further reduce our carbon footprint while continuing to provide customers with efficient means of freight transportation,” said CFNR General Manager Don Seil.
