Trains were suspended in part of Kent this morning due to a shortage of signalling staff.
Southeastern were reporting major disruption on the Medway Valley line, with services being replaced with buses between Strood and Paddock Wood.
Trains were unable to run on any of the lines between the stations, but the line re-opened shortly before 7.20am.
Southeastern has apologised for any disruption and say the delays are likely to last until 8.30am.
