Researchers show economic, environmental and grid-resilience benefits of converting diesel trains to battery-electric

Green Car Congress

In the US, diesel freight trains emit 35 million metric tons of CO 2 annually and produce air pollution that leads to $6.5 Accounting for reduced criteria air pollutants and CO 2 emissions, switching to battery-electric propulsion would save the US freight rail sector US$94?billion billion over 20?years. —Popovich et al.
