History
The Plymouth, Devonport and Exeter Railway Company was formed in 1840 to establish a railway line between Exeter and Plymouth. In 1843 the name was changed to the South Devon Railway and Isambard Kingdom Brunel was appointed as engineer. In 1844 the South Devon Railway Act was passed, authorising the construction of a single-track, broad-gauge line.
The proposed route included a stretch along the coastline between Dawlish and Teignmouth, between the sea and sandstone cliffs, which required a series of tunnels to be cut through the protruding headland. The line had to negotiate several steep climbs and changes in gradient and Brunel’s plan to deal with this landscape was to adopt an experimental system of atmospheric propulsion. Known as the Atmospheric Railway, it was developed by Samuel Clegg and Jacob and Joseph Samuda on the Dalkey Railway in Ireland in 1844. It used a combination of partial vacuum and atmospheric pressure. Instead of a traditional locomotive engine, stationary engines were placed in pumping stations along the line, extracting air from vacuum pipes laid in the middle of the track. Brunel first used the system in 1844 on a five-mile stretch of the London to Croydon Railway. Despite criticism of the system from
various contemporary engineers he also recommended it for the South Devon Railway. The first section of the line opened in May 1846; however, the atmospheric vacuum pipes had not been completed, and initially, a steam locomotive was used. The first atmospheric train ran in 1847; although only between Exeter and Teignmouth. Ultimately the railway suffered from defects, including the deterioration of the leather seals on the vacuum pipes. In 1848 the atmospheric system was abandoned and the line was converted to conventional steam locomotion.
In 1876 South Devon amalgamated with the Great Western Railway, and in 1884 the section of track between Teignmouth Old Quay and Smugglers Lane was doubled. In 1892 the line was converted from broad to standard gauge. Between 1902 and 1905 the section between Smugglers Lane and Dawlish Railway Station was also made into a double line.
Shell Cove Lies next to Phillot Tunnel and has two sea defence structures: the Shell Cove Breakwater and Horse Rocks Retaining Wall. The latter was built at an unknown date between two natural features, stone stacks, known as Horse Rocks. A wall is shown on the Ordnance Survey Map of 1889. The wall provides the north end of Shell Cove with protection from the sea and has been subject to a series of repairs in the C20, including some using rough concrete screed.
Shell Cove Breakwater is probably of 1840s date but was extended later in two phases. It was originally 37m in length but appears to have was extended to 60m by the Ordnance Survey of 1889 (with a kink shown roughly at the 37m mark). It is still shown at this length on the Map of 1933 so it can be assumed that the northern end of the breakwater is of post-war date. The breakwater has had subsequent repairs.
Details
A breakwater of 1840s date, extended in the later C19 and in the mid-C20.
MATERIALS: dressed granite and rubblestone with repairs in stone and concrete.
DESCRIPTION: connecting at its southern end with the cliff face by Clerk Tunnel, the breakwater is of an approximate overall length of 84-94m. It is approximately 5.6m in height from the seaward side and on average 2.5m on the beach side. It is 1.6m wide at the top and 3.8m wide at the base. At roughly 37m north of its southern end the north-easterly direction deviates slightly to the north, marking the second phase of construction. There is another phase of construction further north. The breakwater is quite steeply battered on the beach side.
Repairs include a concrete block fill in the southern cliff face, various patching in stone and concrete, and a section of shuttered concrete repair. The north end is stepped with a screed covering. There are attached C20 steel ladders to each side close to the south end and a modern pole beacon fixed to the top of the north end.

Notification that following a recommendation from Historic England, the Secretary of State for Digital, Culture, Media and Sport has decided not to list Horse Rocks Retaining Wall and Shell Cove Breakwater but is minded to issue a Certificate of Immunity from Listing (COI).
The Horse Rocks Retaining Wall and Shell Cove Breakwater are both architecturally plain structures built of rubble stone and granite on a relatively modest scale with repairs and reinforcement in other materials including concrete screed. They are not among the most impressive historic sea structures to survive nationally and only part of the Shell Cove Breakwater (and none of the retaining wall) is known to date from the pre-1850 phase of the railway. The retaining wall may well have been substantially rebuilt in the later C20. After having given careful consideration to the surviving structure of the pre-1850 breakwater, we note that it has been extended twice since its first construction and its plan has therefore been considerably altered. Therefore, neither structure has strong claims to architectural special interest.
The Horse Rocks Retaining Wall appears to be a later structure than Brunel’s 1846 Atmospheric Railway in its current position, and with the date of construction unclear due to the successive repair and rebuilding work it does not have any clear claims to historic interest. Listed examples of sea walls and other sea defences are mostly of early-C19 date or even earlier and often have strong group value with other listed structures. Regional examples include the sea walls at Exmouth, Devon (1841-2, Grade II) and St Mawes, Cornwall
(1859, Grade II). While the original section of Shell Cove Breakwater dates to the Brunel period, it was a minor structure on a line that has been largely replaced in the subsequent works of 1902-5 and, in conjunction with its substantial later extension over two phases and some major repair work, it is not a good representative example of a pioneering railway structure. Therefore, with little architectural or historic interest and no group value with other listed buildings, the structures fall short of the criteria and cannot be recommended for listing.
CONCLUSION
After examining all the records and other relevant information and having carefully considered the architectural and historic interest of this case, the criteria for listing are not fulfilled. A COI should therefore be issued.
REASONS FOR DESIGNATION DECISION
The Horse Rocks Retaining Wall and Shell Cove Breakwater are not recommended for listing for the following principal reasons:
Architectural interest
* the structures are of little design interest and have had substantial later alterations.
Historic interest
* while the Shell Cove Breakwater has some historic interest as a mid-C19 structure built in relation to the construction of Brunel’s railway, its later extension and alteration have rendered it a relatively poor representative example of a pioneering railway structure;
* the Horse Rocks Sea Wall has no known claims to historic interest.
Group value
* they do not form a group with any listed structures.
