NZ Rail Workers Survive Train Crash, Spark Safety Overhaul

A maintenance worker jumped from his vehicle just seconds before a 1,554-tonne freight train collided with it near the Kaimai Tunnel on April 6, 2025. His quick thinking meant everyone walked away without a scratch.

Two rail workers had been performing routine maintenance inside New Zealand's longest railway tunnel when a communication breakdown left them unprotected on the tracks. Train Control had no idea they were there.

As the workers drove out of the tunnel's eastern exit shortly after 12:40 pm, a 716-metre freight train was approaching from the opposite direction. The locomotive engineer rounded a bend, spotted the vehicles, and immediately hit the emergency brake.

The lead vehicle's driver looked up to see the train barreling toward him. He threw open the door and jumped ten seconds before impact.

The train, slowed from 33.5 km/h but still moving at 19.3 km/h, struck the vehicle and pushed it nearly 28 metres back toward the tunnel. The second worker reversed about 40 metres and escaped collision entirely.

The Transport Accident Investigation Commission discovered the near-disaster stemmed from contradictory procedures and poor radio coverage. Workers believed protection had been arranged, while the protection officer thought they'd finished for the day.

The Bright Side

KiwiRail didn't wait for recommendations to gather dust. The company has already upgraded radio coverage around the Kaimai Tunnel, ensuring workers can communicate clearly in what was previously a dead zone.

Two more safety improvements are coming in January 2027. New procedures will clarify when workers must contact Train Control before entering tunnels, and enhanced communication protocols will govern how safety-critical information gets shared via mobile phones.

The commission noted that timing saved lives that day. The workers had just finished their maintenance and exited the tunnel moments before the train arrived inside, where the outcome would have been catastrophic.

KiwiRail accepted both official recommendations without hesitation, turning a close call into a catalyst for protecting every worker who maintains New Zealand's rail network.
