Southeastern are advising the public not to travel today, as Storm Ciara continues to cause severe disruption.
Fallen debris has caused blockages on a number of lines, and a blanket speed restriction of 50mph for trains is in place.
Passengers have been warned that significant delay is likely with any journey.
A spokesperson said: "As Storm Ciara heads to the UK this weekend, Southeastern strongly advise their passengers NOT to travel today
"If you do decide to travel, there is a high risk of significant disruption and you may not be able to complete your journey.
"If routes become blocked due to fallen trees or other debris being blown on to the line, rail replacement transport is unlikely to be available.
"Exceptionally high winds from Storm Ciara are forecast across the South East area today and in the early hours of tomorrow.
"For safety reasons, Network Rail have implemented a blanket speed restriction of 50mph across all our lines (except the High Speed lines between St Pancras and Ashford) all day today. To mitigate the effects of this, we will be running a revised timetable today."
