Main roads across Kent are all open after the county's gritters spent the night clearing them of snow and ice.
Heavy snow followed by freezing temperatures caused chaos on Saturday, with drivers gridlocked for several hours and others stranded.
Motorists are being warned to take extra care on minor routes across the county as many remain treacherous.
Southern and Southeastern are running normal Sunday rail services, but with some cancellations.
Sarah Boundy, from Southeastern, said: "There will still be disruption because you can't have a day like yesterday and it not affect the next day's service.
"We do really try overnight to get trains to the right depots - they need maintenance, they need to be cleaned.
"Ice can cause damage to the undercarriages of our trains as well so what that will mean today is some trains that are usually eight carriages long, might be running as six or four," she said.
Eurostar said its services were being delayed by up to one hour due to the weather, and it advised customers to only come to stations if they had a confirmed booking for Sunday.
