All Cleveland trains were suspended for almost seven four hours as crews worked to repair a fallen overhead power line at Manly in Brisbane's east.

According to TransLink, services were suspended at 4.40am on Thursday to allow repair crews to access the area once the power was shut off.

Buses began replacing trains between Cleveland and Lindum stations from about 5.40am.

Queensland Rail asked affected commuters to allow extra travel time, with delays varying from station to station along the line.

The line was fixed and services had returned to normal by 11.30am.
