neither solve the issues air travel does. the amount of rail needed to funnel the same amount of traffic one of the larger airports generate would be phenomenal let alone where could you even put it down? then of course comes the small problem of how many miles cross ocean which puts rail right out of the equation.

Seriously, look at an airport. get the number of flights and where they come from and their frequency, now imagine trying to build a sufficient number of rail lines to do the same.

air travel saves time that no rail line could except in short hop scenarios where extra time to process through an airport might tip a balance. let alone you can have nearly an number of planes in flight between two points

London Victoria rail station averages ~207k passengers per day. London Heathrow airport average ~211k. Doesn't feel that unfeasible.

Victoria is the second busiest station in London - Waterloo is busiest, at about 258 passengers a day

Does London Victoria have trains going to Canada, Hong Kong, Moscow? I am pretty sure most Heathrow flights aren’t to Leeds.

The point is: take airplanes where it makes sense (long distance > 600km), and a well-meshed train network for everything else.

Howrah railway station in India handles over 2 million passengers per day.

The number of seats in a long distance train in India with about 24 coaches is about 1780 not including those without seats.

A fully loaded ICE 4 high speed train can pack 830 people, an A380 615.

The answer is multimodal transport and connections. With airplanes, transit takes time and effort - with trains, next to zero. Take, for example, a traveller from New York (USA) to Gaimersheim (DE, Bavaria): airplane connects New York to Munich. Then you travel with the S-Bahn regional train to Munich Central train station, take an ICE high-speed train to Ingolstadt, and switch to the regional train which takes you to Gaimersheim.

you're comparing status quo (super cheap flights, arguably borderline too cheap to be economically sustainable even without factoring in carbon and water vapor externalities) with something that doesn't even exist and then proclaim it's out of the equation. change prices and the equation may surprise you.

Chiming in from Hamburg, Germany with its main station at 550.000 pax per day in 2018. About crossing the oceans: What about floating submerged pipes, maybe going to artificial island hubs in international waters with blackjack and hookers? Has the hype left the loop? Where is your VISION?

Air traffic is a luxury that's not really warranted or necessary. It has a huge environmental cost. I never said rail is faster and better, it's just necessary to prevent climate change that will kill billions of people.

If in the future some modes of transportation are banned, everybody will feel sorry to not have enough railroad and nuclear energy.
