No. For a destination where I am going this summer a train trip is 12h with a stopover and if I want a sleeper cabin, the whole trip is 300€. Plane takes 1.5h and costs 50€.
Also as I'm in the middle of one of those routes, if I were to return home by train, I'd need to get off at 3am.
Here's my solution: tax the living hell out of aviation please, use this money to subsidize trains. There will be more supply and more demand on the rails. We will suddenly have frequent and convenient connections. And we all will be co2-neutral.
Your case is very clear cut, but for some journeys where travel times are closer together, e.g. 1 hour flight versus 4 hour train people do tend to forget that there is extra time wasted going to the airport, checking luggage, boarding, whereas the train is "just there". Depending on your location going to the train station may also be faster than going to the airport, maybe even cheaper!
That said, the price of each journey most likely will always favour flying at the moment.
I have never had a train journey where something hasn’t gone horribly wrong like missed connections, cancelled trains, trains overcrowded with drunk football fans, etc.
Having to look for hotel at night in middle of nowhere or having to sleep in the station because the next train is going tomorrow can ruin the whole trip.
Planes can be cancelled too but it’s not a guaranteed thing like with trains.
The probability of a smooth plane journey feels like 90% while for trains its like 1%
