The three new stations are designed to operate in a similar manner to existing RailCorp stations. They comprise entry structures, an unpaid passenger concourse, a paid passenger concourse, rail platforms and a "back of house" area for station staff and administration functions. These three stations have the same basic configuration with differences in the orientation of entrances and concourse configuration.rnEach of the new underground stations incorporates two "service buildings", one at each end of the station. The service buildings contain: railway signalling/communications equipment, electrical power distribution equipment, traction power substations and sectioning switches; maintenance rooms; tunnel ventilation system axial fans and dampers; tunnel emergency exit stairways.
