Nearly 60 passengers have left Cairns on the first long-distance rail service to be run in almost a fortnight.
Flooding caused by ex-tropical cyclone Oswald had closed sections of the North Coast Line.
A Queensland Rail spokeswoman says a special service left Cairns bound for Rockhampton this morning and it is due to arrive just before 5:00am (AEST) tomorrow.
She says a northbound service will leave Rockhampton tomorrow night.
No transport can be provided south of Rockhampton due to road and rail closures from flooding.
