Unrivalled rail expertise

QuadR’s original scope on the project involved brownfield works including earthworks and drainage, signalling and AutoHaul® operations for the entire 165km of new rail. We were subsequently engaged to provide critical rail expertise to the client delivery team.

Calibre QuadR took delivery ownership for:

  • All permanent way elements
  • Critical west earthworks package (ACJV)
  • Rail over rail (Gudai-Darri over Christmas Creek) bridge
  • Road over rail (Great Northern Highway) bridge
