Design changes for City Rail Link- with video

railimpression_620x310Auckland Transport (AT) has decided to redevelop the existing Mt Eden Station and connect it to the CRL rather than build a new underground station at Newton.

Since the CRL’s concept design was developed two years ago, there has been concerted effort to optimise the design and drive value for money.  The on-going design improvement process included a comprehensive review of all project elements by an international “challenge team” of experts.

The improved design will connect passengers at Mt Eden Station to the CRL which previously bypassed them and improve operational reliability through the provision of a separated east-west junction so train lines won’t need to cross over each other.
