 By late 2012, the new main hall of the railway station and its integrated underground bus station had become operational; during the summer of 2013, the entire complex, including the adjoining "Galeria Katowicka" mall on Szewczyk Square, was officially completed.During the 1960s, work began on the construction of a replacement station for the city's old terminus, Katowice historic train station, which dated back to the nineteenth century.The new complex was designed to serve as a high-profile example of modern architecture; the main railway hall of the building was designed as a collaborative effort between the Polish architects Wacław Kłyszewski, Jerzy Mokrzyński and Eugeniusz Wierzbicki, while the construction of the station was supervised by the noted civil engineer and designer Wacław Zalewski.
