On a recent hillwalk in the remote hills to the south of Scatwell/Strathconon, we came across a line of derelict telephone poles. The poles “marched” (with various atitudes!) over the hill towards Loch Orrin; an unusual feature at an altitude of between 330m and 430m – why were they there? what was their purpose? and when? We were keen to find out.
Lines of telephone poles are, or were at one time, a bit of a blight on the landscape but now we see fewer of them and they are rapidly becoming a “thing of the past” as more phone lines are buried underground. One could argue that they are not of archaeological importance, but they are certainly part of our history. We decided to record these poles and investigate.
The poles are located 4kms south of Scatwell House and stretch for c1.5kms from Loch an Fheoir (NE end GR – NH 3939 5326) to Loch Aradaidh (SW end – NH 3862 5255), following the line of the well-made estate track from Scatwell over to Glen Orrin. Ten disused poles in various states of preservation were seen, most were upright but some had fallen and others were at jaunty angles. The poles are of timber and generally 12cms in diameter and up to 5m in height; many had wire stays. Most had a single step-iron near the top and metal discs with identification numerals. Only one had a timber cross-piece with ceramic insulators near the top, all however had the notch for the cross-piece.
First port of call for information was the estate keeper; he was able to tell us that the line of poles had been constructed for a field telephone system from Scatwell over to Cabaan Lodge, which is now submerged under the Orrin Reservoir. The Orrin Dam was constructed in 1959 as part of the Conon valley hydro-scheme. The keeper also told us that the poles continued for a further 2kms from Loch Aradaidh to a point GR NH 364499 where they disappear into the reservoir. When Sir William Coats Cross (1876 – 1947), a Glaswegian industrialist, purchased the Scatwell Estate in 1919 it included part of Glen Orrin; in the 1920s he established the telephone system to facilitate communication between Scatwell House and Cabaan Lodge, thus negating the need for the two keepers to climb to suitable vantage points and signal the information that a shooting party was planning a visit to Cabaan.
Another local resident who had been born and brought up in Scatwell informed us that her father, as a boy, remembered the telephone line in the 1920s; it was a “wind-up” affair. Wikipedia has an image of a “hand-cranked” phone, and provides us with the information that; “rural and other telephones that were not on common battery exchange had a magneto hand cranked generator to produce a high-voltage alternating signal to ring the bell of other telephones on the line and to alert the operator” – it may be that our field system was similar to this?
I am not particularly technically minded and would welcome any information or comments on this matter
Our day continued very successfully with an ascent of a summit with the curious name of Carn na Cloiche Moire, “Cairn of Mary’s Bell”, and the discovery, on the descent, of yet another illicit still bothy!!
I passed on this article to couple of people interested in telecom history.
Incidentally, another bit of telecom history relevant to the work on the Northern Barrage mne laying.
“A telephone line was run by the Admiralty in WWI to link Corpach to Invergordon. This line was kept in use until 1928 as the only trunk telephone circuit out of Fort William.”
in Feb 21, the line of poles could be followed well down towards Cabaan, though more recumbent than standing (none with crosspiece / insulators). Six-Inch First Ed. has Camban not Cabaan, and the river is still Allt Cam Ban (OS 25k) – both it and the drowned R Orrin have sharp crooks (cam) here. Watson gives Cabaan as Cadha Ban, steep white pass. Take your pick ! Six-Inch Second Ed. has a Bridle Road over the moor, crossing the nameless burn to descend an unfeasibly steep rough brae. One-Inch maps keep the ‘path’ (not track) to the east side until near the foot – also unfeasible as the burn has a cliffed east bank at one point. In fact the traceable line crosses as per 6″ (mini-bridge abutments) and soon recrosses at a rockbar (with prominent telephone pole). A clear line then cuts all down the east side – certainly a track for small wheeled vehicles. The very steep jeep track ascending from Scatwell School is recent (old line lost).
