Network Rail said in a tweet: "Rail services into and out of most major London stations are now - or in the process of being - suspended.
"Travelling conditions are extremely dangerous, caused by fallen trees and debris blocking tracks or debris entangled in overhead power equipment."
Met Office Chief Meteorologist Paul Gundersen said: “After the impacts from Storm Dudley for many on Wednesday, Storm Eunice will bring damaging gusts in what could be one of the most impactful storms to affect southern and central parts of the UK for a few years.”
Other forms of travel are expected to be disrupted by Storm Eunice.
National Highways Head of Road Safety, Jeremy Phillips, said: “We’re encouraging drivers to check the latest weather and travel conditions before setting off on journeys and consider if their journey is necessary and can be delayed until conditions improve.
"If you do intend to travel, then plan your trip and take extra care, allowing more time for your journey.
“In high winds, there’s a particular risk to lorries, caravans and motorbikes so we’d advise drivers of these vehicles to slow down.
“Drivers of other vehicles should be aware of sudden gusts of wind which can affect handling and braking, and give high-sided vehicles, caravans, and motorbikes plenty of space.
"In the event of persistent high winds we may need to close bridges to traffic for a period, so please be alert for warnings of closures and follow signed diversion routes.”
