By sheer chance, quantum pairing, or harmonic convergence if you like, some years ago I was fortunate enough to receive a 1928 reprint Ordnance Survey “Contoured Road Map”, one inch to the mile, number 137, linen-backed, as a present. Very nice.
This covers an area bound by Launceston – pronounced, “Lanson” – and Callington, Cornwall, and Okehampton and Tavistock, Devon, the very epicentre of the legendary, and somewhat ethereal Boltorr branch.
It turns out this includes the very focus of the railway which exists only in my mind’s eye.
If you’d care to examine the entire map – click on the image for a larger version – you’ll find the location of the Boltorr branch somewhere along the Tavy, by-passing Okehampton, on its way from Tavistock to Moretonhampstead and, eventually, Exeter.
