(Francisco Kjolseth | The Salt Lake Tribune) A diesel-powered train bound for the Dallas area nears shipment at Stadler Rail's plant in Salt Lake City on Friday, Jan. 5, 2024. The diesel train's engine compartment is designed so it can be converted to a battery-powered system in the future. Stadler is building a battery-powered version of this train in a project with Utah State University's ASPIRE center to demonstrate that it's possible to run a commuter rail line on batteries.
