In July, Lockheed Martin completed the build of NASA’s X-59 test aircraft, which is designed to turn sonic booms into mere thumps, in the hope of making overland supersonic flight a possibility. Ground tests and a first test flight are planned for later in the year. NASA aims to have enough data to hand over to US regulators in 2027.

Price per km of track goes up exponentialy the faster you want to go, which means they will either have expensive tickets or will be unprofitable.

The rail network should be a service not a for profit organisation

Still, someone has to finance it. In the worst case you have a high speed rail network with high operationg costs that nobody uses, but taxpayers still need to maintain.

If it’s there (and not terrible), people will use it. Will it break even on the costs? Maybe. Maybe not. Still worth it, however.

Spain and china managed just fine. Rail costs way less than 20 lane highways.
