Rail Delays on Brisbane's Northside Rail passengers on Brisbane's northside are experiencing delays this morning. Photo: Michelle Smith Rail services have resumed in both directions between Bowen Hills and Northgate stations, after an earlier overhead powerline fault at Woolloowin caused length peak-hour delays. Thursday morning commuters on the Airport, Doomben, Caboolture, Ferny Grove and Shorncliffe lines had to wait up to 30 minutes, after trains were reduced to using two of the four tracks. Translink said all four tracks were back in operation, but there would be residual delays of up to 20 minutes across the network as services got back to normal.
