Commuters heading into London face delays to rail journeys this morning.
Some trains heading to Waterloo East are being diverted to Cannon Street because of a "smouldering power cable" on one of the platforms.
Travellers were first warned of the disruption in a tweet by Southeastern more than an hour ago. Some passengers say they have been trapped on trains for two hours.
Rail staff and members of British Transport Police are now moving along carriages giving information.
The first tweet warned: "There may be some platform alterations for trains through #WaterlooEast for trains heading towards London Bridge due to safety inspections being carried out alongside platform B."
It then said: "A power isolation is being requested through Platform B at #WaterlooEast due to a smouldering power cable. All trains towards London Bridge will go through platform D."
Those diverted to other stations can use London Underground at no extra cost.
Southeastern told affected passengers to remain on their trains and listen to onboard announcements. It has apologised for the delays.
