North-east train services have been restored this morning after a signalling failure.
Journeys in and out of Aberdeen station were disrupted and engineers were called to address the issue.
CLEARED: Disruption caused by a fault with the signalling system at Aberdeen has now ended. Services are no longer affected by this problem.
