Train by Ben-UK
The main train station is in the centre of the city, next to the local bus station. There are frequent trains to Krakow (78km), Wroclaw (180km),Oswiecim (for Auschwitz)(33km),Warsaw (303km).
International trains to Berlin, Prague, Vienna.
Unfortunately, the rickety old concrete bridge from the station down to ul. 3 Maja, does not give you a very good first impression of Katowice.
