UPDATE 8AM JULY 6: Ground under the Blue Mountains rail line was continuing to shift following a landslip near Mount Victoria, NSW Minister for Regional Transport and Roads Sam Farraway updated on Tuesday night (July 5).
"Crews are mobilised to begin initial repair work and will get started once it is safe to do so. There's a big job ahead of us but I'll keep the community and freight industry updated along the way as we get the line back online for passenger services and our state's supply chain," the minister posted on Facebook.
Blue Mountains MP Trish Doyle said on July 6 that the latest disruptions have highlighted the need for long-term solutions to bolster the Blue Mountains rail line.
"Whilst I acknowledge that recent weather events are beyond our control, they have once again highlighted the fragility of our rail network and the need for long-term solutions to counteract the challenges faced by the Blue Mountains line," she said.
"The NSW Government must treat this as a matter of priority. Our public transport trains and services have been neglected for far too long under the current government and that needs to stop, now.
"Our community deserves a fully functioning transport network that can withstand these extreme weather events. If the NSW Government insists on labelling us as part of Greater Sydney then treat us as such and give us reliable, resilient trains and services that meet our community's needs," she said.
"The State Government has assured us that they're working around the clock to rectify the issues that have arisen in the past week however we may still see reduced passenger and freight services in the Upper Mountains for weeks, possibly longer. Meanwhile communities like Mount Victoria, after an incredibly tough few years, find themselves once again facing impacts on local businesses, tourism and access to key services."
UPDATE 1.30PM JULY 5: NSW Minister for Regional Transport and Roads Sam Farraway has warned rail travel in the Blue Mountains will be affected for the "next few weeks" following a landslip near Mt Victoria.
Mr Farraway has uploaded photos of a large sinkhole caused by the wet weather.
"There is a large 40 metre long, 20 metre wide and 60 metres deep sinkhole at Mount Victoria next to the Main Western Line," he posted on social media.
"This will impact freight operations and passenger services over the next few weeks. I'm working with freight industry to assist them in finding viable alternatives to move goods and supplies.
"Crews are onsite, including technical engineers, to understand the full impacts.
"Maintenance crews will work actively around the clock to restore full access to the line, undertaking track and other infrastructure repairs once it's safe to do so."
