The local community in a remote village, cut off by wintry conditions, has worked together to help a pregnant woman who went into labour.

Roads were blocked to Balgedie near Kinross. Nearby off-duty midwives offered to help and were assisted to the scene by local farmers, after an alert was sent out on social media.

Emma Niven whose husband Rob was one of the first to get involved with his tractor spoke to the John Beattie radio programme.

She said: "It's just been the most magical morning. An emergency message went out on Facebook looking for midwives for our neighbour who was in the late stages of labour and was stuck.

"We just couldn't get her out and nobody could get to her so we got the tractors out and negotiated a couple of midwives and brought them to her just in time at a critical stage where the baby's head was actually stuck.

"So all has turned out well but oh my goodness what a morning."

In a post on Facebook, the new mum said: "Wow! I am absolutely blown away by you all! What an incredible community we live in!!! Baby boy is here safe and sound after a terrifying home birth which was only possible thanks to you all!

"Thank you to our amazing neighbours, friends, midwives, ambulance and police services who walked, dug and ploughed their way to us!! And my clever sister for posting on here! Baby and I are now safely on our way to hospital! Pics, name & weight to follow. Thank you all x x x"

ScotRail say they have teams hard at work trying to clear tracks and get services moving again.

The Edinburgh bus driver who skillfully swerved to avoid a car in the treacherous weather conditions on Wednesday has been speaking to the BBC.

Charmaine Laurie told the Victoria Derbyshire programme she didn't have much time to react but managed to steer clear of a Mini which had skidded on the ice.

She said: "I just tapped the brake but my back end started to slide out so I had to take my foot off the brake and just try and glide it through the space that was there."

There were about 20 passengers on the bus at the time, including children.

Footage of the incident was filmed on a dashcam by van driver Gareth Smith.

Ms Laurie added: "A lot of it was just instinct but we are trained to be aware of these kind of situations.

Asked how passengers reacted, she said: "No-one really said anything afterwards.

"But one lady getting off the bus asked me how I was and said 'well done'."

Clear up operations continue across the country as public transport slowly starts to get back in action.

There are reports of people struggling to get the essentials like milk and bread as the weather hampers deliveries.

Pictures have been posted on social media showing empty supermarket and shop shelves.

One local shop owner in Glasgow has been telling BBC Radio Scotland's John Beattie programme: "We've had no deliveries at all for the last two days. No papers as well.

"Everyone's been looking for the milk and bread."

A Tesco delivery driver told the same programme supplies were now beginning to get through.

"The main roads are clear," he said.

"We are getting in to most of the stores now and they are replenishing their shelves."

Will we ever see a pavement ever again? The snow in Edinburgh is more than ankle deep.
