[locomotivebreath]

Which the railroads would never figure out . It’s normal for locomotives to be away from service facilities and yards for weeks at a time . Not all yards , even large ones have refueling capability as is . Railroads also don’t like to invest or especially maintain infrastructure lol . The technology might be able to be used in some circumstances l like long haul intermodal trains out west , where they can move a 10k ft container trainer 400 miles in a day from terminal to terminal . I’d say this is more of an experiment to make the federal govt happy . Like when the big railroads experimented with ultra low emission gen set locos for light switching in yards . Looked good on paper , state and federal agencies where excited . Did they work ? They would move lol but not much weight , it would take 2-3 of them together to perform the same task ! The railroads just quietly scrapped them over the years .
