Just before 2.30pm, Queensland Rail told commuters the problem had been resolved.

Earlier, a QR spokesman said electricians were on-site to fix “an overhead power line issue” affecting that segment of the Shorncliffe line.

Commuters were warned to expect delays up to 45 minutes when Queensland Rail announced the suspension about 1.40pm on Thursday.

“Customers can expect delays until our crews can rectify the issue. We are online and available to assist with your enquiries,” the spokesman said.
