Works and planning

The Helidon to Calvert section of Inland Rail will be built predominantly within the existing rail corridor and the Department of Transport and Main Roads’ Gowrie to Grandchester protected rail corridor. A study area has been identified to consider refinements.

Work is expected to include building:

  • 47km of new dual gauge track
  • an 850-metre long tunnel (approximately)
  • 30 bridges, including:
    • 26 rail bridges (with 12 rail bridge crossing roads and 1 grade separated rail bridge crossing rail)
    • 3 road bridges crossing rail in Helidon and Gatton
    • 1 grade separated pedestrian bridge crossing rail in Gatton
  • crossing loops at Helidon, Gatton, Laidley and Calvert.
