The 1937 built, former London and North Eastern Railway A4 pacific locomotive “Sir Nigel Gresley” makes its way at the head of the “Tynesider” charter service from Newcastle, northern England to London’s Kings Cross station, through a snow covered scene near York, following heavy snowfalls across the region, Saturday Nov. 27, 2010. Severe weather warnings for almost all of the United Kingdom were in place Saturday with heavy snow, widespread icy roads and bitter temperatures forecast. Some 10 inches (25 cm) of snow is expected to fall over higher ground, while parts of the Midlands and London will not escape a dusting. Overnight temperatures across the UK plunged well below zero again, after a day when much of the country was badly disrupted by the earliest widespread snow for 17 years. (AP Photo/PA, John Giles)
