Trains were unable to run between Margate and Ramsgate for several hours last night (February 24) after road work signs were thrown on the track at Broadstairs.
The debris caused a power failure meaning passengers had to use bus services between the stations while the power supply was restored.
It is believed the road signs were thrown from the bridge on Ramsgate Road, by Broadstairs College, which is undergoing work to the footpath due to a crash last September.
Southeastern say: “Staff on site found debris thrown onto the track which caused damage to the power supply.”
A resident in the area also reported a group of youths who threw a traffic cone from the repair works site at her home.
