A temporary track will help move a derailed Victorian train that collided with a truck and injured 19 people, as experts warn legal action is likely.
Two cranes have been brought in to move the carriages away from the Phalps Road, Pirron Yallock level crossing on the Warrnambool line.
The level crossing was one of three that was "fast-tracked" for completion 17 months ago, but now isn't expected to be upgraded until the end of the year.
"The question needs to be asked, should works have happened sooner?" Shine Lawyers transport accident law expert Cameron Cowan told AAP.
"There's little doubt that infrastructure improvements may have prevented this tragedy from occurring and we need to examine whether works in this area should have been expedited.
"In light of the nature of this terrible accident, it is likely that legal action will result."
The 41-year-old truck driver is in Royal Melbourne Hospital in a stable condition, while 18 others were taken to hospital with cuts, bruises and broken bones.
Trains have been replaced by buses along the route since Wednesday, while investigators collect evidence and the train carriages are shifted.
A V/Line spokeswoman said the company will need to repair the track after the area is cleared and will start looking at whether the carriages can be salvaged.
The level crossing is categorised as a "passive crossing", with no boom gates and flashing lights, but stop signs and train crossing warning signs are in place.
Construction works at the level crossing were delayed as there was an issue getting power to the site.
The government says boom gates and signals will be installed by the end of the year.
Two near misses have been recorded at the site - in June 2011 and February 2012.
Passenger Cheryl Scully was on the train returning home to Warrnambool and remembers seeing the truck driver on the ground.
"I saw the driver laying just down below the window near the cattle grid there and that frightened the life out of me," she told Nine News on Thursday.
The Australian Transport Safety Bureau estimates an investigation will be completed within 12 months.
