The central hall of Budapest's Nyugati railway station will be closed to the public starting on Friday due to renovation work on the landmark building's roof, a state secretary of the innovation and technology ministry said on Tuesday. Laszlo Mosoczi added that the renovation project will take seven months to complete. National railway MAV's chief, Robert Homolya, said the 9 billion forint (EUR 25.6m) project involves the reconstruction of 8,200 square metres of roofing, the replacement of electrical wiring and the passenger information system.
