Wallan derailment

On 3 February 2020 a vehicle had struck overhead wiring at Wallan,[2] leading to a fire in a signalling hut which caused extensive damage to wiring and affecting signalling on the North East line between Donnybrook and Kilmore East. Trains were signalled through the affected section using Caution Orders. On 6 February, this was changed to using Train Orders,[2][3][4] a manual safe-working system.[5] The points at the Wallan Loop were set to the straight ahead position and locked. No speed restriction was put in place.[2] V/Line services in the Wallan area had been delayed in the weeks leading up to the accident due to the ongoing faults.[5] On 20 February, trains were routed through the Wallan Loop for rail cleaning purposes. A speed limit of 15 kilometres per hour (9.3 mph) entering the loop and 35 kilometres per hour (22 mph) exiting the loop was put in place. Two V/Line trains passed through the loop before the XPT.[2]

The accident occurred at 19:43, when NSW TrainLink's 07:40 Sydney-to-Melbourne service operated by an XPT set entered a turnout near Wallan, about 45 kilometres (28 mi) north of Melbourne, and derailed. The train, comprising power car XP2018 (leading), five carriages and power car XP2000,[6] was carrying 155 passengers and seven crew members.[2][7] The train was running about two hours behind schedule at the time of the accident.[8] As the train passed through the turnout, leading power car XP2018 and the first four carriages derailed, with one carriage and rear power car XP2000 remaining on the track.[9] The train had entered the loop at a speed of between 114 and 127 kilometres per hour (71 and 79 mph).[2]

The first 000 call was made at 19:45.[2] Two people were killed: the train's driver and the pilot.[5] Emergency services confirmed that 12 people had been taken to hospital.[8] The injured were taken to the Kilmore Hospital, Kilmore and The Northern Hospital, Epping;[8] one person was airlifted to the Royal Melbourne Hospital.

The derailment caused the closure of the North East line and the adjacent broad gauge line, impacting freight services and V/Line services to Seymour, Shepparton and Albury.[10] On 23 February, the Australian Rail Track Corporation commenced removal of the train from the rail corridor.[11] Seymour and Shepparton V/Line services resumed on 1 March, followed by Albury services on 2 March.[12] Major speed restrictions were in turn enforced on the North East line, with NSW TrainLink temporarily terminating services at Albury.[13] Passengers reported that the train had been gaining speed at the time of the accident, after being stopped due to a signalling issue.[8]

In the days preceding the accident, trains were scheduled to pass through the turnout in the straight ahead position. On that day, trains were instead diverted into a passing loop while work was carried out on the adjacent track. The Victorian branch of the Australian Rail Tram and Bus Industry Union reported that V/Line drivers were refusing to traverse through the section of track that the XPT service derailed on.[14]

Regularly scheduled XPT services between Sydney and Melbourne resumed on 4 June. Of the two power cars, XP2000 was returned to service while XP2018 remained in store as at May 2021 at Maintrain, Auburn pending the completion of investigations.[9]

On 24 February 2023 after being rebuilt and rail tested XP2019 (formerly XP2018) returned to revenue service operating a Sydney-to-Dubbo service. The renumbering of the power car occurred as it was involved in a fatal accident with rail tradition to never use the same number after a fatal incident. Its return to service followed a rebuild and rail trial of XP2019.
