Let’s be realistic. I love long distance train journeys, but mainly for recreation. Being on a train for 3-5 days is pretty exhausting no matter how comfortable. I’ve done the 30 day Amtrak pass before and it was fantastic but I wouldn’t be looking forward to that if it was a work trip where I want to fly in and then get back to my family as fast as possible. There’s no way that can compare to a 5-6 hour flight+2 hours at the airport.
