The purpose of this paper is to examine a unique sociotechnical system in its historical context to better understand and appreciate how a naturalistic organization enacted five key characteristics identified as critical to sociotechnical systems by theorists hundreds of years after the fact. The paper presents an examination of the history and context of this unique method of organizing.

history of copper mining in Cornwall and Devon.
A history of the ECMR line and the later standard-gauge line are provided in the first post about the line which can be found on this link:. The adjacent image is a schematic sketch of the length of the original 3ft 6in narrow gauge line. In order to cope with the significant difference in levels between the River Tamar and the surrounding countryside, it was necessary for there to be a rope worked incline from Incline Station down to Calstock Quay.
Steam locomotives were used for the upper section, a stationary engine and counter-balance system for the Incline, and horses on the Quay. The Incline section was under the control of a stationary engineman, assisted by a coupling man on the Quay, a signalman at the top and a signalboy at the halfway loop.
It is thought that only one major accident ever occurred, involving two runaway trucks containing granite, but this resulted in no injuries as the points were deflected allowing the trucks to end up in a field. Manure for the farms and coal for the mines was brought in and ore exported. The quay continued in use long after the incline was closed. A wagon lift was provided alongside the viaduct which was completed in to allow access from Calstock Station down to the wharf.
Seven men and a horse have stopped work to pose. Also, note that there is a wagon on the incline. You can only see part way up the incline here — it curved around to the right and continued to climb. Lime Kilns lay off to the left as did the River Tamar.
In order to ensure compatibility for wagons the track gauge on the wharf would have had to be increased from 3ft 6in to standard-gauge. The map is the OS Six-inch Map of The river is visible on the map both to the north and south of the village. The incline was a just over metres in length and curved away from the river as it climbed.
It was 2, feet m long on a gradient of 1 in 6. It was self-acting, but a stationary steam engine was provided at the top. The incline is shown on the adjacent Six-inch OS Map. It was single track with a passing loop halfway, and a three-rail section above it as shown on the next imagewhich is an extract from the 25 inch OS Map. When the ECMR line was built, the incline was taken over by the railway company. There is evidence of realignment of the incline: the later route was higher up the hillside and reduced the sharp curve near the bottom.
An electric bell system was installed for the operation of the incline, later replaced by a telephone. Two loaded or three empty wagons were moved on the incline at a time. Two bridges were still in evidence on the route of the incline in The first of these accommodated a single track lane which ran underneath the incline just to the south of the passing loop and is shown in the adjacent image, c Roger Winnen.
The second was directly under the location of the passing loop and is shown in the next image, c Roger Winnen. These structures were not in good repair in I have not been able to establish their present condition in ! Also visible are the Danescombe Hotel the last building on the left , which has had various other names over the years. The lime kiln and the supporting bridge centre still exist. The Danescombe Valley behind the curve in the Incline Railway is believed to be the route taken in the 9th Century by the Danes, before their battle at Hingston Down, which resulted in Cornwall losing its independence.
Anyone who has visited Calstock and climbed the steep flight of steps from Kelly to the station will remember them at 2. To give another locator guide, the Rectory, Sand Lane is indicated at 3. Horses performed wagon movement on the quay. The incline had to bridge a minor road which is shown in the adjacent image. Above, the top of the incline in including, on the left, the remains of the water tower which also accommodated the winding engine, c Roger Winnen .
The adjacent sketch from the s is drawn from a vantage point a little further back from the photographer of the image above. The image below was taken at the same time in as that of the water tower and shows the remaining storage shed, c Roger Winnen. The buildings pictured were all part of the site of what was known as Incline Station.
The station site is shown in the map excerpt below which comes from the inch OS Map of Each building is in evidence including the locomotive shed. The next picture shows the view in back South across the site of Incline Station towards the incline. It is a Google Streetview image and is taken from just to the West of the parapets of the arch bridge which carries the single-track lane over the route of the ECMR. Below the next picture are two excerpts from the inch OS Map. Not visible on either of these two maps is the village of Albaston nor the hamlet of Drakewalls, both of which were to the West of the line.
It is also possible that the mine produced arsenic and arsenical pyrites in the s. In , this mine was recorded as employing 32 people — 27 men, 3 females and 2 boys. Hence the later name of the station near the mine which was named after the village of Gunnislake. The mine was worked from the 11th Century to also , with periods of closure. Hence the later name of the station near the mine — Gunnislake.
The following photograph was taken in the early part of the 21st Century and shows the derelict buildings of the mine. The route of the ECMR is shown above in the left half of the sketch map. Caltock Consols, Drakewalls are also shown along the route of the line. The picture is taken from the A, c Roger Winnen. The bridge appears below. Station Road bridge had sheet metal parapets. It was advertised for sale in Edward Storey took over the quarry in from the Gunnislake Granite Co.
He erected buildings for polishing and dressing the granite. The stone was mostly excavated by hand as the quarry was close to the houses and they had to be very careful when blasting. In a day, a skilled worker could cut ten feet of kerbstone from rough granite weighing nearly a ton or fashion 70 to 80 paving stones. In its heyday the quarry employed people. The quarry yielded hard fine-grained granite which was used in Devonport Dockyard and the fortifications around Plymouth.
The quarry closed in but soon reopened in when it was taken over by S. They supplied stone for the breakwater in Dover. There were lots of sidings in the quarry including one which crossed the main opening on two granite pillars and led to a small quarry to the south known as Hardwall Quarry which was worked by Thomas Westlake between and The quarry was nearly a quarter of a mile wide and feet deep in places.
The route of ECMR is shown in red. The route of the branch-line is shown in Green. North of the junction with thee branch-line and beyond Station Road bridge there was a siding which gave access to Sandhill Brickworks.
It was a single track, gated s-ding as shown on the enlarged view of the inch OS Map from The works was already disused at the time the map was drawn. To the North and West the railway crossed the fields first on an embankment and then in cutting, as shown by the red line on the adjacent satellite image from The next map excerpt from the inch OS Map shows the route of the line in The first fed Plymouth Works in North Dimson and is seen in full on the inch map below.
The second was a tramway which served Gunnislake Clitters Mine. However it was taken over in by Gunnislake Clitters mine. At the beginning of the 20th Century it was treating ore from several local mines including the Tavistock mines. The site remains are quite extensive with some abandoned buildings and blackened burnt tailings between the railway and the Chilsworthy road at North Dimson, Gunnislake opposite the Clitters Engine Houses.
Further along the Chilsworthy road up on the right are some old building in use as industrial premises and most of all the Arsenic stack flues mostly gone which stands at just under ft tall, originally this was ft tall but the top 12 feet were blown off by lightening in ! The main chimney at the works, shown in the adjacent image taken at around the same time was hit by lightning in In , the Plymouth Brickworks was recorded as being in existence at Lower Dimson.
The group of hoses on the left of the map still remain, as does the large building on the inside of the curve of the track. Little else is visible. Gunnislake Clitters Mine was a large copper mine near Gunnislake.
Its layout was as shown on the adjacent inch OS Map from The mine sett was leased from the mineral owners the Duke of Cornwall and the Rev. Spargo in his book The Mines of Cornwall; Statistics and Observations  says that it had a inch pumping engine, a inch winding engine and a inch stamps engine as well as a foot waterwheel used for pumping.
It employed people. The engine house is depicted in the adjacent photo in the early 21st Century, c Brian J Williams. Although Gunnislake Clitters opened in , the main period of production was between and Production: 40 tons of copper ore between and For the periods and the mine produced 33, tons of 8.
The metal bridge parapets can be seen in the Google Streetview photograph below. The black arrow shows the location of the picture immediately above the map. From this point West the road and old railway route run roughly parallel across the north flank of Hingston Down. The village of Chilsworthy is very close to the old line, just to the North.

The South coast is much and deeply indented, and has some good harbours. Falmouth is one of the finest harbours in Britain. The indentations on the North consist of shallow bays with few or no harbours.
