Queensland Rail says it is likely the train line between Rockhampton, in the state's central region, and Cairns, in the far north, will be closed for another couple of days.
North Queensland network manager Shane Hinchcliff says repair crews are assessing unconfirmed reports of damage between Proserpine and Bowen after Tropical Cyclone Ita.
"It's unlikely to be buckling but we may have lost some ballast out of the track structure ... we've got guys on the track at the moment," he said.
"So we'll probably get our guys across that ... to make a full assessment."
Mr Hinchcliff says parts of the line may be open sooner than others.
"We'll open up sections as it is safe to do so," he said.
"It's likely that Rocky to Mackay will be the first section open.
"Then after that it'll be a case of as we get the recovery work complete we'll open up those corridors."
