With a train, you have to pick the correct train, and then leave

By interacting with people, you often can handle the most
complicated train ride, but yes, it might be more complicated with
train.
Complication that, in many cases, is severely complicated by being
tired, exhausted, and out of focus from a long flight.
It could be there are only two more generations be able to travel
extensively by jet airplanes. Perhaps zeppelin travel will return.
Trains are about 5 times more energy efficient that planes, and about
3 times that of autos. While there is little safety difference between
planes and trains, there is a significant difference between that of
autos. Dealing with trains is also much less common for those in
North America than from other locales. While I agree making sense of
train schedules, and at times even knowing which direction the train
should be heading to find the correct tracks, can be challenging.
Patrik is right. Sometimes you need to ask. :^)
