we should also be aggressively be invested in electric/solar/hydrogen commercial airlines. Last I checked they have limited range and capacity but if we were putting as much money and time into as we were into the military, we'd already be there.

It absolutely will not for one giant obvious reason - land. If you think this is going to lead to people being ok with getting their land eminent domain'd to out in support for passenger rail, I have a bridge. And it isn't the fossil fuel lobby that runs the existing tracks. It's the rail lobby.

I wondered about that too. As the article points out (contra the headline) it's not that the short flights are popular. They have been subsidized as connections to longer flights, but the math is changing. Rather than raise prices on the shorter flights, lines are just slowly cutting them.

Greetings from Spain, which built the world's densest high-speed rail network in less than a generation (for scale: Spain is about the same size as Texas, with a population of 49 million). Since then, high-speed rail has almost entirely replaced short-haul flights. Rail is faster, cheaper & greener.

What it means in reality is air travel is going to stop in the immediate term and the barest possibility of a rail replacement would be a decade on the optimistic side. A solution for now needs to be discussed and not just railway pipe dreams.

It does exist. There are rail lines between all sorts of cities. They just have to be used. Yes, they will need to have investments made in them. From Chicago you should be able to take a train to: Green Bay, Madison, Rockford, Dubuque, Peoria, Rock Island, Evansville, Eau Claire, Appleton (1/2)

Muncie, Bloomington, IN, Cedar Rapids, Rochester, MN, Dayton, Lima, OH, Decatur, IL, Nashville, Louisville, Knoxville. Just off the top of my head. ALL Of those places have rail connections to Chicago. ALL OF THEM. Just use them.
