MSO7906 - Simonsbath to Porlock Railway (Monument)
Please read the caveat document.
Type and Period (1)
The Exmoor and Porlock Railway was proposed to transport iron ore from Simonsbath (SS 77 39) to Porlock Weir (SS 86 47) for shipment to South Wales. An agreement to construct the line was signed in 1855, but mining activity on Exmoor ceased shortly after. Construction contracts were let out in 1860 and substantial diggings were made before the project was abandoned. Sections of the line can still be detected. There is some evidence to suggest that a plan existed to build a standard gauge railway along the same lines about 1826 to open up access to Exmoor. The 'Pinkery Canal' (MSO6847) was possibly linked to this scheme to work inclines down to Simonsbath and Cornham (SS 74 39). [1-3, 21] The track bed of the Simonsbath to Porlock Weir railways survives as an intermittent earthwork in the RCHME East Exmoor Project area. A length of track bed follows the contour (at approximately 425 metres) from the Forest boundary at SS 8331 4360, around the headwaters of Weir Water, to the Porlock-Exford road at SS 8445 4404. On the eastern side of the road, the earthwork is well-preserved. It runs from SS 8460 4420 to SS 8455 4514. The earthwork comprises a levelled portion 6 metres wide, with a bank 1 metre wide and 0.7 metres high on its eastern edge. A further length of track bed runs from SS 8440 4583 to just above the A39 at SS 8495 4629. This part of the line was surveyed using differential GPS as part of the RCHME East Exmoor project.  A plan of part of the proposed route shows three inclines to take the railway down to Porlock Weir.  Part of the western most of these three inclines was excavated between Westcott and the Toll Road. This was noted by M. Jones as visible between SS 8506 4655 and SS 8508 4667.  A well preserved section of the track bed, from SS 8272 4212 to SS 8221 4161, was recorded at 1:2500 scale using differential GPS as part of an archaeological survey of the Larkbarrow area.  The route of the Simonsbath-Porlock railway is clearly visible as an earthwork on aerial photographs, running from approximately SS 8496 4629 (SS 84 NW) to SS 7676 4160 (SS 74 SE). Some sections are better preserved than others, and the track appears to fade from view east of Blackpitts Farm, Exmoor. [9-16] The description of the route differs from that shown on the aerial photographs and the Ordnanace Survey Archaeology Division 6 inch maps. [18-21] Gradiometer Survey picked up a linear anomaly at approximately SS 843 457 which is post-medieval in date.  The earthworks forming the trackbed of the railway were created, but the track was never laid due to the iron resources in the area having been found to be too poor. Much of the railway commissioned by Frederic Knight can be traced still (in 2013).  A small part of this feature was covered by one of the geophysical survey areas of the Dig Porlock project in 2013, using earth resistance and gradiometer survey equipment. Following assessment of the results of the surveys, it was recommended by Carey Consulting that further work to compare the geophysical results to the earthworks would be of value.  Part of this feature was present in the survey area for a measured field survey in 2013, undertaken as part of the Dig Porlock project, run by the Exmoor Moorland Landscape Partnership Scheme.  Similarly, as part of Dig Porlock volunteers and students of the University of Leicester undertook resistivity and magnetometry survey over part of the railway.  The railway was intended to transport lime to the reclaimed moorland, to neutralise the acidic soils, and to move iron ore from Exmoor to the coast.  The railway was included as part of Cornwall Council's survey of Porlock Allotment as the bailing area for the proposed Mires restoration on Alderman's Barrow Allotment.
