Meet the team working on the “Big Four”- the four City Rail Link tunnels as they detail the construction of this complex tunnel system. You’ll see how the two CRL tunnels branch out into four tunnels at Maungawhau Station
This video lets you look inside the two CRL tunnels, four civils constructed tunnels, and the Newton Junction box. Learn about the different construction methodologies used that will later serve the City Rail Link with trains running in four directions from four tunnels.
