On Thursday 15 October 1998, at about 1407 hours, Train 9282, comprising 4 English Electric multiple unit cars running from Wellington to Johnsonville, derailed while negotiating the turnout from the up main to the down main at the south end of Wadestown.
The 2 leading cars were derailed. There were no injuries. A worn switch rail on the turnout which permitted 2 bogies to be directed to the up main as the remainder of the train followed the intended route to the down main caused the derailment. A safety issue identified was the failure of the Tranz Rail inspection regime to detect and correct the worn switch before it reached derailment condition.
