The railway's proposers envisaged direct links from Penzance and Falmouth to Waterloo by avoiding the change of gauge. The projected line would have gone across open country, populated only by villages, with Camelford being the single significant town. But much was made of the minerals and mines that could have been served. Having traced the alignment on a map, I reckon that it would have crossed Davidstow Moor, later the site of the airfield. In an uncanny reflection of today's debate, the prospectus makes much of the benefits of avoiding the South Devon line with its gradients and curves, by boasting that it could connect with London "..at a saving of 30 miles and with improved gradients".
I have established that the Central Cornwall Railway Act was passed in 1867, but the project was abandoned by the Board of Trade on 16 March 1870. Only later, on 18 August 1882, was the North Cornwall Railway Act passed, but it could be argued that the later railway was even more remote, opening between Halwill Junction and Launceston on 21 July 1886, with Wadebridge to Padstow not opening until 27 March 1899. Interestingly, the Engineer for the North Cornwall line was WR Galbraith, who had been intended as the engineer for the Central Cornwall. As we know, the Withered Arm closed to Wadebridge on 3 October 1966, with the link to Padstow closing on 30 Jan 1967.
It is interested to read the optimistic forecasts for the railway in the prospectus and one can only wonder how many people were prepared to commit to buying £2 share in the endeavour. Clearly not enough !
I hope this is of interest.
Very best wishes,
