A FREIGHT train derailment in the Blue Mountains has put a freight line out of action.

The train derailed on Wednesday last week (14 December) between Lawson and Linden.

Repair works will involve removing cracked rails and smashed sleepers, according to a social media post from Blue Mountains MP Trish Doyle.

Minister for regional transport and roads Sam Farraway said maintenance crews are undertaking inspections onsite to assess damage to a 10-kilometre section of track.

“This line is a vital component of our supply chain and the NSW government will work closely with industry as crews work hard to get it repaired and reopened,” Mr Farraway said.

“The track in both directions is impacted. It is expected more than 15,000 sleepers will need to be replaced, 120 broken rails fixed, and electrical work undertaken to restore signalling along the entire section of damaged track.

“The adjacent undamaged track will remain open to diesel trains until Sunday morning, which will keep goods and commodities moving while final repair plans are being established, and to allow freight operators time to find alternative paths.

“We will continue to provide regular updates to the rail freight industry and passengers on progress of the repairs.”
