Queensland Rail says the line between Brisbane and Cairns has reopened after floodwaters damaged large sections of track during Cyclone Ita in the state's far north.
Nearly 80 kilometres of track had to be replaced, mostly around the Proserpine area, north of Mackay.
North Queensland manager Michael Mitchell says he expects the repair bill to be in the hundreds of thousands of dollars.
"There was quite a lot of damage all the way from Mackay to Cairns but we saw most of the damage from around Mackay through to Bowen, in particular around Proserpine we had around 15 washouts," he said.
"Around about 78 kilometres of track was completely washed away had had to be rebuilt.
"Our priority at the moment was to get the track opened.
"We haven't done the numbers yet but it would have cost ... quite a few hundred thousand dollars to repair the track."
