The local railway infrastructure was also extensively changed, a total of 20 new high speed and high capacity tracks were laid in the station area, along with improvements to security systems and miscellaneous passenger-facing service infrastructure. The adjacent squares located at either side of the entrances to the station were intentionally developed to accommodate various new areas, including a railway office, a new metro line, a bus terminal, a shopping centre, offices and parking spaces; reportedly, in excess of 100,000 parking spaces were added along with various private access roads. By December 2010, the northern tracks and rail yard had been fully constructed and associated control equipment installed in a centralised traffic control center.
