~5h is how long a train takes from Warsaw to Berlin, compared to ~1h by plane (~2-3h including getting to and from airport), and I know multiple people who still prefer the train - even when they are able to easily afford any mode of transportation.

With the train, you have way more freedom in choosing the time and the hour. You have multiple trains leaving during the day, and you can choose 30 min before needing to hop onto one. Also, if you miss one, you just wait for the next one.

Also, on the train you can work, relax and stretch your legs or eat freely. So it doesn't feel like lost time really. Planes often do, even if you travel business.
