npub1x4ep49e7cdcvwtyhs27a6j5xlet703mqfag7l22fhjepuyceexvqeurfyr (npub1x4e…rfyr) I'm not a giant train expert, but isn't what you're describing already the case?

Afaik electric trains just have some batteries for switching tracks and other moments when they are temporarily not connected to the overhead lines, they can't really run long distances on batteries alone.
