We need bullet trains, not more passenger jets.
I wonder if research into sonic boom physics could translate over to high speed aerodynamics generally, to include the useful models for high speed trains.
Interesting thought; I'd hope so. Maybe some material physics/chemistry research that makes some stuff cheaper for trains (I'm not an engineer so totally out of my depth here).
Efficient High-speed rails are already possible and have been since the 70s, it's not a lack of science that stops them from being a thing, it's a lack of desire from government officials being paid by private interests to do things less efficiently because people are getting paid.
