If you're traveling throughout Poland, train is a great way to travel. The national train service has timetables and a route planner in English on its website, www.pkp.pl. You can purchase rail tickets when you're in Poland, or purchase a Eurail Poland Pass (Buy Direct) in advance. Express trains can take you from one end of the country to the other overnight or within a day. Trips between large cities may be only a couple of hours long.
