The railway line between Aberdeen and Dundee was closed for over an hour due to a track defect.
ScotRail made the announcement of the closure on Twitter at 5.27pm.
Network Rail Scotland engineers responded to the reported defect by carrying out a safety inspection.
The inspection was carried out between Laurencekirk and Stonehaven.
It was expected to be finished at 8pm, but ScotRail announced the line had been reopened at 6.48pm.
