Main Rail Occupation (60 hour window) was the only time the line was not operational in which weather events included temperatures above 42 degrees Celsius and rainfall. During this window, the existing bridge was removed, existing piers demolished, new bridge installed and new track installed, with trains re-commencing immediately after the window had expired.​
