Domestic and international trains connect at the station to most major cities in Europe; these are operated primarily by Polskie Koleje Państwowe.

During July 2009, it was announced that the Polish government had signed an agreement with the Spanish construction firm Neinver for the latter to build a new integrated transportation hub and commercial center in the middle of Katowice, including the redevelopment of the existing railway station.

Around the start of the twenty-first century, it is believed that, on average, around 520 trains per day were stopping at Katowice Railway Station, while the facility was also being used by roughly 12 million passengers annually.

[1] Through the station, Katowice is connected to major cities including Vienna, Budapest, Kiev, Berlin, Ostrava, Prague, Bratislava, Zilina, Hamburg, Moscow and Minsk.

[1][3] As planned, the redeveloped railway station is not to be entirely newly built; instead, it is intended to retain several existing elements of the building, albeit renovated and modernised where deemed to be suitable or necessary.

[1] The problematic cup-shaped pillars are one such element, being reinforced rather than removed; a grand new entrance into the main hall of the station is to be developed between the two cups.

A glazed structure which connects between the railway station and the new retail and office facilities shall be constructed; the shopping and office complex are to be located upon a newly built elevation, composed primarily of perforated steel structures, these are reportedly intended to provide an aesthetically pleasing lighting effect via their highly reflective characteristics.

[1] The first phase of construction was focused on the main station building itself, which is features a one-story hall featuring multiple ticketing counters and information desks, along with 31 retail outlets and trade points, a spacious waiting area for passengers, and compressive closed-circuit television coverage across the complex.

[1] The entire complex, including the adjoining Galeria Katowicka mall on Szewczyk Square, was completed by the summer of 2013, with the new main hall and its integrated (underground) bus station having entered operation by late 2012.
