Train services between the Sunshine Coast and Brisbane are cut after a gum tree fell across the tracks north of Caboolture.

Passengers were warned to expect delays of up to an hour between Caboolture and Landsborough on Tuesday morning after the tree took out power lines.

A TransLink spokesman said the tree was found just after 3am and the delays would likely be less than an hour.

Buses were replacing trains between Caboolture and Landsborough as a shuttle train ran between Nambour and Landsborough, causing delays of up to half an hour.

Translink technicians were on site assessing the problem.
