Going underground

A look at the City Rail Link route beneath the earth

Britomart Station 11m below ground

Becomes a through station, enabling more frequent trains with many services more direct.

Aotea Station 13m

Expected to be NZ’s busiest train station with entrances near Wellesley and Victoria Streets.

Karangahape Station 33m

Coming to Mercury Lane. The underground platforms will go as far as Bereford Square where there could be another entrance in the future.

MtEden Station In open trench

Will be expanded and re- developed to cover both the existing Kingsland to Grafton line and new CRL Mt Eden to Karangahape Line.

$ 168.8m spent buying land and buildings for the project.

$ 155.5m spent on 51 surface land titles and buildings.

$ 13.3m on 58 underground land tracts at an average of $ 229,310 each. CRLL still needs to buy more underground land.

$ 4.419b to be spent in total on the project.

3.45km twin tunnels due to be completed in 2024.

Transport authorities estimate CRL stations will need to cope with 54,000 passengers an hour during peak periods by 2035.
