Doesn't work for all of us. I can peacefully fall asleep from the noise of a CFM on an Airbus. On a train, rickety being chucked around all the time and always too hot, nope.

I can do 10h on a plane fine. 3h on a train does me in every time.

I can't sleep in a seat, which rules out aircraft for any reasonable carbon or dollar price.

At least on trains I have a chance. Googling how the climate controlled worked before my previous trip helped, but that followed a hot journey.
