The big freeze continued to bring Britain to a standstill as further snowfall overnight forced the cancellation of over 2,000 flights and hundreds of trains, the closure of two airports and chaos on the roads.
Some 300 passengers were forced to spend the night attempt on a stuck Southern train in West Sussex after heavy snow caused a series of line failures.
And forecasters say there could be another eight inches across the east of England today as blizzards are forecast across the South East.
Transport Secretary Philip Hammond said a review of how transport operators had coped with the weather conditions was under way.
Southern Trains were telling commuters this morning “Sorry there are no trains at all until at least 10am”.
Tens of thousands of passengers due to fly out of Gatwick and Edinburgh today saw their travel plans in tatters as the airports closed for a second day.
A Gatwick spokesman said: “We are doing everything we can to resume operations, however conditions have deteriorated considerably,” he said.
“Our teams are working around the clock to make the runway safe for aircraft to use and get our airlines and passengers flying again.”
More than 4,000 schools were closed in England on Thursday.
One of the worst-affected areas of England is South Yorkshire, where snowfall of up to 30cm (12in) brought parts of the county to a standstill.
Overnight, temperatures hit lows of -11 in County Tyrone, Northern Ireland, and -14 in the north-western Highlands.
There could be up to 30cm of snow in southern England by the end of Thursday.
There will also be more snow showers in north-east England, he said.
