How to travel around Poland?

It seems that the most convenient  and often also the fastest way to travel around Poland is by train. The best connections are among Kraków (Cracow), Warsaw and Gdańsk, as well as on the route Warsaw - Poznań. However, the whole country has a very dense network of railway connections, which can be used  to reach almost every corner of the country.
