Fly with us through the CRL tunnel

Come fly with us!
We sent a drone through the City Rail Link tunnel so you can get the feel of your future train journey underground from the redeveloped Maungawhau Stations to the familiar downtown Waitematā (Britomart).
It's a 3.4km journey.
The first of those two 3.45-kilometre-long tracks for Auckland’s newest railway line - the City Rail Link - has now been laid connecting, underground, Waitematā (Britomart) and Maungawhau Stations.
That newly laid track will carry trains south from Waitematā Station (Britomart). Installation of the first track began in August 2022. Work started just as CRL’s tunnel boring machine, Dame Whina Cooper, was nearing the end of its tunnel excavating drive.
CRL Ltd’s main contractor, Link Alliance, and railway infrastructure company, Martinus New Zealand, installed the track on what is one of the steepest sections of railway in New Zealand. From Waitematā, which sits below sea level, the track climbs around 70 metres to Maungawhau. At its deepest point, the track runs 42 metres underneath Auckland’s busy Karanga-a-Hape.
