An interim report from the Transport Accident Investigation Commission (TAIC) has detailed the sequence of events leading to a June 6 train crash at Khandallah Station. A two-car Matangi electric train passed a red signal and was diverted onto a runaway line, eventually striking a concrete stop block at 33kph. The collision resulted in injuries to six people, including two crew members who were hospitalised and four passengers who sustained minor injuries.
The signalling issues began at approximately 6.50pm when the system registered a "dropped track" condition while the train was travelling north towards Johnsonville. This caused the system to incorrectly interpret the track as being occupied, triggering a visual error message on the train controller's screen. However, this warning did not produce an audible alarm and disappeared after 25 seconds.
At approximately 7.06pm, the train passed a red signal and was diverted onto a runaway line. Although emergency brakes were activated, the train's trip lever failed to engage a trackside safety device designed to automatically apply brakes. The train lost power after its pantograph disconnected from the overhead wires and then struck the concrete block.
Train controllers in Hutt Valley received no automatic alerts following the collision. Instead, emergency services were alerted by passengers and members of the public from nearby homes.
