Dozens of train passengers have been rescued from a snowdrift and thousands of homes remain without power after heavy snow hit parts of the UK. More than one hundred people were stuck on the Edinburgh to Inverness train for six hours after it got stuck near Aviemore. <br/><br/>Some thirty thousand homes in Northern Ireland still have no power, but the number has dropped to about 4,500 in Scotland. Forecasters say the worst of the snowfall may be over but warned that ice could prove treacherous on roads.
