Matt Baker and Julia Bradbury are in the Yorkshire Dales, to see how one of the world's greatest railways is keeping communities together. They also re-home some travelling cave spiders and explore a remote location which inspired one of the finalists in the Countryfile Photographic Competition. On his Cotswold farm, Adam calls in a horse whisperer to help him move some stubborn Exmoor ponies. Meanwhile John Craven investigates the demise of our dairy farms and asks whether there is any way to make money out of milk.
