The UK is being warned to brace for a further cold snap with “disruptive snow” set to sweep in across parts of the country as temperatures plummet.
The Met Office has issued three new yellow weather alerts for snow and ice.
One of the warnings covers the Midlands and a part of northern England and is in place until 11am today.
The second warning is in place across a large part of Northern Ireland until 10am today, while the third is in place in the northern tip of Scotland until 10am on Wednesday.
The Met Office has warned up to 20cm of snow may accumulate in the worst affected areas as the country experiences its “first taste of winter”.
National Rail warned the cold climate would impact various routes on the Northern Rail until at least 2pm on Tuesday.
Impacted areas included the Bradford Interchange and Huddersfield, and also between Halifax and Hebden Bridge and Hull.
Mersey Rail issued an alert warning passengers that due to the potential of snow and ice covering tracks, the first service on each line in north west England would run without customers to ensure conditions could be checked.
Travellers were advised to check their local rail app or social media and plan their journeys ahead.

Motorists were also put on high alert, with the National Highways issuing an amber severe snow alert for roads across the North East and North West of the country. Road users were advised to take extra care and avoid the area if possible.
Impacted roads included the M26 between J21-J23, the M1 at Leeds and Sheffield and the M56 at Manchester.
It comes as the first amber cold health alerts of the season have been issued by the UK Health Security Agency (UKHSA) covering all of England, except the South, until 6pm on Saturday.
An amber warning is issued when the weather is likely to “cause significant impacts across health and social care services”, according to the UKHSA.
That includes the potential for a rise in deaths, particularly among older people or those with health conditions.
Dr Agostinho Sousa, head of extreme events and health protection at the UKHSA, said: “It is vital to check in on vulnerable friends, family and neighbours to ensure they are well prepared for the onset of cold weather. Particularly if they are elderly or otherwise at increased risk.”
Meanwhile yellow health alerts – the second lowest alert level – are in place for the South East, South West and London.
Temperatures dropped to -7.8C (18F) in Tulloch Bridge in the Scottish Highlands in the early hours of Monday, which is the lowest temperature the UK has seen since last winter.
Snow dusted grounds across Aberdeenshire, including at Glenshee Ski Centre and at Corgarff, as well as alongside the A939 near The Lecht in the Cairngorms.
Snow also blanketed the mountain of Ingleborough, while there was a sprinkling of frost near Clapham, in the Yorkshire Dales.
More expected in coming days
Met Office spokesperson Nicola Maxey said snow has mostly fallen on hilltops so far, with 2cm falling in Lerwick, Shetland.
But more snow and ice are expected over the coming days, with temperatures plunging to below average levels for the time of year.
“It is going to be quite a widely cold week,” Ms Maxey said. “A few degrees below average both day and night for most of the country.”
