There has been a profound improvement to air quality in all U.S. cities in recent weeks thanks in large part to the grounding of most commercial aviation. It's an irrefutable argument for a robust national rail system powered by renewable electric sources.

Jets can still do the cross-country trips but we need to get rid of all of the short flights. High quality rail not only gets jets out of the air, it gets cars off the interstates.
