Extinction Rebellion was also involved in the action. Hundreds of other demonstrators in and around the airport’s main hall carried signs saying “Restrict aviation” and “More trains”.
Don't care about your trains (seriously, what is it with big government types and trains?). If we can get more blimps for air travel though I'd be OK with that because I think blimps are cool.
In actuality, no. In terms of passenger-mile-gallons diesel electrics sip fuel compared to turbofans. The diesel cycle is just so much more efficient than the brayton cycle that there's no meaningful comparison between the two.
Like, that's not even controversial. It's how commuter rail can remain economical against buses.
The problem with nationwide rail is:
Atrophy of the established 19th century rail base.
Failure to develop routes to match population trends since the Eisenhower Administration.
The overall size of the country, which was always going to make coast to coast flights economical.
Extremely low average population density and long distances between the top 25 population centers.
The balance falls somewhere between the two. To achieve European or Japan like efficiency you need equivalent population. "Trains" don't replace cars... subways do. But to get to the point of subways you need incredibly high population density.
The high speed city-to-city routes continued to develop after the war because the Asian and European post war economies couldn't afford mass car ownership until the 70's or 80's.
Meanwhile the US was flying high with a postwar economy that saw basically the top 75 population centers get jet service with 707's.
To make high speed work in the US, you have to make it work between Los Angeles and San Francisco, and between Boston and Philadelphia. Until that works, there's nothing to build off of.

Trains are way worse for the environment than air travel. Airports just need a few hundred acres of land for planes to land.
Train tracks require thousands of miles of track that has to constantly be maintained. Trains are also less efficient and run on the dreaded diesel.

The problem with nationwide rail is:
The nemesis of trains in America never was air transportation. It was always highways and interstates. THIS IS HOW MANY SHINKANSEN-SPEED TRAINS YOU'D NEED TO MAKE IT ALL WORK IN THE US. The cost would be in the trillions.
You need significantly more trains to compete with cars and air? Meaning they're less efficient?
Thanks, we agree. Efficient doesn't just mean fuel efficiency.
Don't shift goalposts like a leftist.
