BBC weather reporter Susan Powell said: "Even where the conditions become comparatively quieter, do bear in mind that, thanks to the cold, there is a risk of icy stretches just about anywhere.
'Significant and disruptive'
"The wind is playing a big part in making the situation worse - there is drifting snow across the north east of England.
"By the end of the night we have to switch our focus south-westwards because it looks like we could see a weather feature... that could bring some significant and disruptive snow."
East Midlands Trains, First Capital Connect, Greater Anglia, London Midland, London Overground, Southeastern and Southern were among the rail operators reporting major delays.

London Midland said trains between Lichfield Trent Valley, Four Oaks and Redditch could be cancelled or delayed at short notice.
Greater Anglia said services could be cancelled and its trains were running a reduced speeds meaning delays of up to half an hour were possible.
First Capital Connect said trains between Brighton and Bedford were being delayed by up to 60 minutes.
Meanwhile trains between London Paddington and Reading were being delayed by up to an hour by a signalling problem.

Snow forced the closure of the A66 in Durham and Cumbria. The A628 in South Yorkshire was also closed for several hours on Monday while Highways Agency contractors cleared the drifting snow.
Many other roads were also affected - a lorry toppled over on the M40 early on Monday leading to the closure of the southbound carriageway between the M42 junction and junction 15 at Warwick.
The Highways Agency advised drivers to plan their journeys or consider delaying their plans if the weather becomes severe.
A spokesman said: "Our roads will be treated whenever there is a risk of ice or snow, and our winter fleet works around the clock, but we need road users to give them the space they need to do their job.
"We advise drivers to pay particular care at locations where local conditions such as road gradients, bends or overhanging trees mean that there may be an increased risk of ice.
"There is still a need to drive with care, even after road surfaces have been treated."
The East of England Ambulance Service issued a warning after reports of at least a dozen sledging-related injuries.

"The fun really isn't worth it if you wind up with a painful injury in A&E."

Birmingham Airport was also affected, with some departures and arrivals cancelled and delays reported.
Gatwick Airport also experienced delays.
Heathrow Airport said disruption was being caused by low visibility. A spokesman said: "When there is low visibility, more space has to be left between aircraft.
"Many airports have plenty of spare runway capacity so aircraft can be spaced out more during low visibility without causing delays and cancellations.
"Because Heathrow operates at almost full capacity, there is simply no room to reschedule the delayed flights."
Catterick Racecourse in North Yorkshire announced Wednesday's racing would be cancelled because snow and freezing ground made the track unusable.
