How well build is the train network in your country? Do you use it regularly? Why or why not?
Personally I travel by train a lot and just couldn’t do a lot of stuff if I could go by train. For example I recently moved for university and I would have a huge problem visiting my hometown if not by train.
Sadly, no. Trains in the US are generally not a viable form of transportation except for local travel in a few large cities.
A few years ago I made a three hour trip by train. The arrangements were inconvenient, the travel was slow, the facilities were in poor condition, and it was relatively expensive. I would not do that again unless most of those things change.
