What a bunch of nuts! This makes even less sense than the Biden administration's suspension of new permits to build LNG plants, which would help substitute natural gas for coal. As you know, natural gas produces less CO2 than coal for equivalent energy.
New contributor CreatedInSpace, who Lucas McCain suspects is LustyLad come back from the dead, had some interesting things to say about this in another thread. See posts 33, 23 and 29:

CreatedInSpace believes real "0 carbon emission" electric trains will only make sense with a build out of nuclear power plants. Do you think that's going to happen in California? And he notes that "it’s still always most efficient to use the source power as close to, and converted as few times as possible, to its final mechanical output." Meaning diesel locomotives make more sense than electric trains. And that's before considering you have to create the infrastructure from scratch and replace the diesel locomotives with electric ones. Or that California's probably going to fall flat on its ass in trying to generate adequate base load electricity without fossil fuels or new nuclear.
I wonder if the end result will be that long haul diesel trucks end up substituting for long haul diesel locomotives. So carbon emissions are higher than they would be otherwise. Or maybe the railroads have to swap locomotives when they cross into the PRC (Peoples’ Republic of California.) This doesn’t seem very efficient.

And, absent something like that, we barely have enough baseload power to keep what we have today supplied without the grid creaking and rolling brownouts affecting many areas of the country when temperatures reach extremes. Besides that, demand for powering data centers and AI is skyrocketing.
Further, even if we had vastly more baseload power from nuclear or other sources, getting it to rolling locomotives in remote areas would be staggeringly expensive. You'd either have to build third-rail electrified tracks like some short distance trams and commuter trains use, or some sort of overhead line system like the old streetcars and electric buses used in some cities. And it would have to extend for many hundreds (or even thousand) of miles. It seems to me that would be grotesquely cost-prohibitive.
I suppose you could power electric locomotives with railcar-sized Li-ion battery packs, but how much would that cost? Maybe in a decade or two we'll have batteries that are much less expensive and about an order of magnitude more energy-dense, but until that time this just doesn't seem remotely feasible.
Moving passengers over relatively short distance via light rail is one thing; transporting massively heavy railcars over long distances is an altogether different ballgame.
