An investigation is under way to determine how six wagons of an empty grain train derailed while shunting near the main street Wagin just after 6pm on Sunday, as workers scramble to reopen the line on Friday. The accident happened near the corner of Tudor and Unit Streets in Wagin, just 500m from the main street, and caused quite a spectacle for residents — many of whom ran down to the site to take pictures and video. A spokeswoman for rail lessee Arc Infrastructure said its teams were on-site and would perform “required track repairs” once the derailed wagons — which belong to CBH Group — were cleared by rail operator Aurizon. She said the cause of the derailment was yet to be determined and an investigation had been launched. The train was travelling at low speed within Wagin station limits, when the wagons derailed. No one was injured. The track between Wagin and Woodanilling is closed to rail traffic while the repairs take place. Arc hopes the line will be back in action on Friday. WA’s 2000km-plus network of grain rail lines are owned by the State Government but leased by Arc Infrastructure, with trains owned by both CBH Group and rail operator Aurizon travelling along the network of tracks. The derailment could not have come for a worse time for Australia’s biggest grain exporter CBH Group, which is in the middle of its biggest grain exporting program in history. A CBH spokeswoman said the company would work with Arc to inspect and re-open the line “as soon as possible”. The co-operative has been trying to shift grain to port as quickly as possible after receiving a record 21.3 million tonnes of grain last harvest, to make the most of high grain prices before the northern hemisphere crop comes onto the global market in a matter of weeks. The line stretches from Newdegate in the east to Wagin in the west, and is used to cart grain from bins dotted along the line before connecting with the Albany to Avon line, before it is carted from Avon to Kwinana for export. Arc declined to comment on when the most recent derailment occurred on its network. The Moora to Millendon Junction section of Arc Infrastructure’s Midland railway line was closed for three weeks after a CBH train driven by a Watco driver derailed in March 2020. The derailment occurred near Noland Avenue in the Upper Swan, and 12 wagons towards the back of the CBH train were affected. Separately, the West Toodyay to Miling Line was reopened in late January after nearly nine months of closure after a bridge crossing the Avon River at West Toodyay was damaged by floods in February last year. Arc reopened the line at the tail end of WA’s record harvest in late January after 10 weeks of repairs which were stalled by the Department of Planning, Lands and Heritage’s lengthy approvals process.
