NZR'S KAIMAI TUNNEL NEARS COMPLETION ON MAJOR CUT-OFF

A new cutoff on the North Island of New Zealand involves a tunnel 8.85 km long constructed through a mountain ridge generally volcanic in origin. The Kaimai tunnel has been constructed through difficult geological conditions by a combination of bored and manual methods. Substantial water inflow made it necessary to provide a large central invert drain which precluded use of conventional ballasted track. The tunnel is being equipped with the first paved concrete trackbed in New Zealand.
