Since trainsets are stored overnight at numerous terminals, the infrastructure needed to charge up many sets of batteries at all of these locations will be substantial, including the transportation of electricity to the overnight storage locations.
As to the comments of increased renewable energy, my electric provider offers the option of having my home supplied with renewable energy. Funny thing, though, it costs more, even though some of the renewable energy sources (wind, solar) are subsidized.
This doesn't even delve into the environmental issues of deriving the materials needed for battery construction and for disposition. And then there are the environmental issues for manufacturing and constructing alternative power sources, as well as their disposition. Where I live, wind power generation is popular, but there is a prohibition on windmills within 3 miles of the Lake Huron shore because of bird and bat deaths. And there is ground contamination from leakage of lubricants from wind turbines. The cost of conventional power includes disposition of residue, such as ash. We have yet to see the cost of the disposal of alternative generation equipment as it wears out. I fear that much will be dumped into landfills.
