The existing C3 contract involves the construction of two underground railway stations, the redevelopment of an existing station and the tunnels connecting them.

Contract C5 will include track alignment in multiple stages with associated overhead line and signalling plant and equipment relocations, extending the platform at the existing station including egress footbridges and building two new public pedestrian footbridges and a new road bridge, heavy retaining structures and earthworks associated with the grade-separated tracks.
