The steel structure rises to a height of 20 metres and spans the 150 metres length of the existing
Western Range, which separates the concourse from the main train shed.
Arriving passengers enter via a gap in the restored Western Range and from here they have
access to the original Victorian booking hall. There is also a mezzanine of retail outlets, which
shares the curved form of the Birmingham Selfridges and is similarly studded with round disks.
