It's Sunday 25th June, and we're back down in Devon to pick up two awkward stations - Samford Courtenay and Okehampton. The line is only served by GWR/National Rail trains on summer Sundays ONLY, and at Okehampton, the Dartmoor Railway then runs services to nearby Melton Quarry/Viaduct. They sometimes run trains back to Sampford Courtenay too.
