Kaimai Tunnel Kaimai Tunnel The Kaimai Tunnel is a railway tunnel through the Kaimai Range in the North Island of New Zealand. Since it was opened in 1978, it has held the title of longest tunnel, at 8.879 kilometres, in New Zealand, assuming this distinction from the previous title holder, the Rimutaka Tunnel. It is part of the Kaimai Deviation, which was constructed to bypass the old route of the East Coast Main Trunk Railway through the Karangahake Gorge (part of which has been preserved as the Goldfields Railway). The Kaimai Deviation is a 24 km line between Waharoa and Apata, including
Quitaque Railway Tunnel feet below its ridge of about 2,800 elevation. The tunnel was originally long. After a train wreck in the tunnel in 1973, the line was closed for eighteen months while the tunnel was shortened to its current length, and the rails were upgraded to handle heavier traffic. As of 1976, it was one of very few railway tunnels still in use in Texas. The line was abandoned in 1989. In 1993, the Texas Parks and Wildlife Department acquired the abandoned right-of-way, and the tunnel is now part of Caprock Canyons State Park and Trailway.
