The final round of changes were completed by 2007. It included refurbishment of the building roof and concourse foundations, an upgrade of platform 10 with escalators and a lift replacing the ramp, the relocation of all ticket booking offices to the main entrance under the main dome and new LCD passenger information displays installed on the platforms, subways and concourse. In March 2009 an escalator replaced the lift to platform 12 and 13, with platform 13 also extended west into daylight along the alignment of the former platform 11.
