Somerset Coal Canal
Encyclopedia
The Somerset Coal Canal (originally known as the Somersetshire Coal Canal) was a narrow canal in England
, built around 1800 from basins at Paulton
and Timsbury
via Camerton
, an aqueduct
at Dunkerton
, Combe Hay
, Midford
and Monkton Combe
to Limpley Stoke
where it joined the Kennet and Avon Canal
. This gave access from the Somerset coalfield
, which at its peak contained 80 collieries, to London
. The longest arm was 18 miles (29 km) long with 23 locks. From Midford an arm also ran via Writhlington
to Radstock
, with a tunnel
at Wellow
.
A feature of the canal was the variety of methods used at Combe Hay to overcome height differences between the upper and lower reaches of the canal, initially by the use of caisson lock
s and when this failed an inclined plane and then a flight of 22 locks.
The Radstock arm was never commercially successful and was replaced first with a tramway
in 1815 and later incorporated into the Somerset and Dorset Joint Railway
. The Paulton route flourished for some years until the coming of the railway and closed in 1898. Much of the course of the canal has since been used for a railway. In October 2006 a grant was obtained from the Heritage Lottery Fund
to carry out a technical study on one of the locks and associated structures at Combe Hay.
and mining began in the area, however transport was a major problem because of the poor state of the roads. This cost and the potential for cheaper delivery of coal from south Wales
via the Monmouthshire Canal led to the proposal for a canal which could transport the coal to Bath and Wiltshire
. Initial surveys were conducted during 1793 by William Jessop
and William Smith
under the direction of John Rennie
who presented the report on 14 October 1793 estimating the cost of construction of the canal at £80,000. Smith, who also worked at the Mearns Pit at High Littleton
, made the original observations leading to his important stratification theory
by observing the dips
in the geological strata
through which the canal was cut. Smith became Surveyor to the company, but was dismissed in April 1799, apparently because he had used his position as surveyor to buy a local house at advantageous terms. He then set himself up in a private practice in Bath but was re-engaged by the company in 1811, to provide advice when repairs became necessary to the canal bed.
The canal was authorised by an Act of Parliament
entitled "An Act for making and maintaining a navigable Canal, with certain Railways and Stone Roads, from several Collieries in the county of Somerset, to communicate with the intended Kennet and Avon Canal, in the parish of Bradford, in the county of Wilts
" of 1794, and further detailed surveys were carried out by Robert Whitworth and John Sutcliffe, who was then appointed as chief engineer.
In May 1795 tenders were invited for the first section to be built from the meadows near Goosehard (or Gooseyard) near Paulton to Hopyard in the Parish of Camerton. In June 1795 a contractor, (Houghton & Son from Shropshire), started the terminus at Paulton meadows using local labour. This first section of canal was completed on Monday the 1st of October 1798, the first load of coal along the canal was delivered to Bath via Dunkerton. Some 14 collieries at Timsbury & Paulton were connected to the Timsbury basin and Paulton meadow terminus by tramways. This involved the construction of three tramway bridges over the Cam brook. A further bridge at Dunford was required for the Canal, at this point tramways connected the Withy Mills and Radford workings. The course of the Cam brook was modified at various places to protect the canal from erosion. In 1799 William Whitmore and his partner, Norton, offered to build a balance (or geometrical) lift without payment, on condition that if successful they were to have £17,300 and a royalty of 4 pence per ton of goods passed.
The design of the caisson lock was not a success, on the 15th February 1798 the first descent failed. Mr. Weldon (the inventor), made one successful descent on the 7th June and said "I will undertake to pass 1,500 tons of goods through the lock in 12 hrs". Tenders were invited on the 28th June for further constructions. Two more attempts to use the caisson lock took place on the 11th April & the 2nd of May (only the latter was successful). By the 22nd August 1799 the second rebuilding of the caisson had been abandoned. It was replaced by three locks and an inclined plane, but the plane was not successful either, and the company proposed to raise more money to finance the building of a flight of 19 locks to replace it, the use of which would incur an additional toll of one shilling per ton on all traffic. This was vigorously opposed by the owners of the Kennet and Avon Canal
and the Wilts and Berks Canal
, on the grounds that the price of coal to their customers would be too high. After negotiation, the company obtained a new Act of Parliament on 30 April 1802, which authorized the formation of a separate body called "The Lock Fund of the Somerset Coal Canal Company", with powers to raise the sum of £45,000. The money was raised by the Kennet and Avon, the Wilts and Berks and the Somerset Coal Canal each contributing £15,000, and the one shilling surcharge was to be levied until the capital had been repaid, after which it would cease. The act set the tonnage rates to be charged:
Fractions of a Mile to pay for Half a Mile, and of a Ton as a Quarter of a Ton; Rates for Wharfage to be determined by the Company. In addition to the above Rates, One Shilling per Ton is paid on all Goods to the Lock Fund, which also receives Three Farthings per Ton from the Coal Canal company. The boats were weighed at Midford where a Weigh house was constructed in 1831. The boats would be floated into a one-ended lock, the gate closed and the water drained. This left the boat resting on a cradle suspended by angled rods attached to a beam which took the weight of the boat. One-pound weights were then added to a pan with one pound being equivalent to one hundredweight
until the system was in equilibrium and the weight was recorded. The weigh house at Midford was one of only four known to have been built in England and Wales.
The canal opened in 1805 and was used for passenger traffic as well as coal. In 1814 the Benedictine
monks who came to Downside Abbey
are said to have used the canal for the last stage of their journey. Another cargo carried by the canal was limestone from Combe Down
. The peak level of cargo carried was in 1838 at 138,403 tons resulting in over £17,000 of tolls being paid. Cargoes of over 100,000 tons were common until the 1870s when competition from railways reduced the amount carried. The canal went into liquidation in 1893; it closed in 1898 and was finally abandoned in 1904 when it was sold to the Great Western Railway for £2,000, and used as a branch of the Bristol and North Somerset Railway. The closure caused problems across the Somerset coalfield especially to the pits in the northern area, which had relied on the canal for transportation.

was an inadequate source of water above Camerton, and the mills along it had water rights. Each narrow boat travelling through the series of locks (22 of them each 6 ft (1.8 m) deep) with a 25-ton load of coal caused 85 tons of water to be discharged into the brook below the locks. As a result the canal was designed with all 22 locks in one flight near Combe Hay and a pumping engine to raise water from the Cam – the first canal to entirely depend on pumping. A potential solution to the water supply problem was the use of Caisson Locks as proposed by Robert Weldon, three of which could replace the 22 conventional locks, because it wasted no water, however the technology had only been tried in a one-third scale prototype. Each lock was 80 ft (24.4 m) long and 60 ft (18.3 m) deep and contained a closed wooden box which could take a barge. This box moved up and down in the 60 ft (18 m) deep pool of water, which never left the lock. The box was demonstrated to the Prince Regent
(later George IV
), but had engineering problems and was never successful commercially or built elsewhere.
It was temporarily replaced with an inclined plane
by Benjamin Outram
who had successfully installed inclined planes at the Peak Forest Canal
in Derbyshire
, whilst 22 locks and a Boulton & Watt Steam Pumping Station, capable of lifting 5,000 tons of water in 12 hours, were built to the latest design with metal plate clad wooden gates.
Construction. The two images show a recently uncovered (2009–10) Spillway / Drain (c1796) at Upper Midford, a location where a Caisson to take the canal from the 180 ft level to the 134 ft level at Midford Aqueduct was proposed.
Each Caisson would have had such a drain for maintenance purposes over the exit arch made to the same dimensions. The following extract from The Bath Herald Paper provides the details of the chosen sites.

was the terminus of the northern branch of the Somerset Coal Canal and was a central point for at least 15 collieries around Paulton, Timsbury
and High Littleton
, which were connected to the canal by tramroads.
On the northern side of Paulton basin was the terminus for the tramroad which served Old Grove, Prior's, Tyning and Hayeswood pits, with a branch line to Amesbury and Mearns pits. Parts of this line were still in use in 1873, probably all carrying horse drawn wagons of coal. The southern side of the basin served Brittens, Littleborrok, Paulton Ham, Paulton Hill, Simons Hill terminating at Salisbury Colliery. In addition the Paulton Foundry used this line. The entire line was disused by 1871 as were the collieries it served.
The area has been designated as an ‘area of special architectural or historic interest, the character or appearance of which it
is desirable to preserve or enhance’ under section 69 of the Planning (Listed Buildings and Conservation Areas) Act 1990
.
's Frome to Radstock line completed in 1854 which took traffic away from the tramway. It finally closed in 1874 with the Somerset and Dorset Railway's extension to Bath , built along its route from Radstock to Midford. Another branch line was constructed in 1882 from Hallatrow to Camerton, running alongside the canal for the last 1.5 miles (2 km) of its route. The Great Western Railway
built a railway line (the Bristol and North Somerset Railway
) over much of the canal route from Limpley Stoke to Camerton, where it joined the existing 1882 branch line from Hallatrow to Camerton. This opened in 1910 for passenger and goods traffic, closed for the First World War, reopened after the war but ran for passengers only for two more years in the mid-1920s and finally closed to all traffic in the 1950s. The line was used in the 1950s Ealing comedy film The Titfield Thunderbolt
.
Despite the building of railways along both arms, there are traces of the Paulton arm of the canal and of the Radstock arm. A short stretch of the canal where it joins the Kennet and Avon at the Dundas Aqueduct
was restored during the 1980s, and is used for moorings. Excavations of the old stop lock showed that this had originally been a broad (14 feet (4 m)) lock that at some point was narrowed to 7 feet (2 m) by moving the lock wall. While some canal features are on private land, the towpath may survive in places as a right of way, while the later railway between Midford to Wellow is being surfaced to form part of National Cycle Route 24. It has been proposed that a statue, commissioned by Sustrans
, of William Smith
, the father of English Geology, will be sited next to the path on the line of the canal commemorating his work as surveyor on the canal and his recognition of the significance of rock strata.

. The peak level of cargo carried was in 1838 at 138,403 tons resulting in over £17,000 of tolls being paid. Cargoes of over 100,000 tons were common until the 1870s when competition from railways reduced the amount carried. The canal went into liquidation in 1893; it closed in 1898 and was finally abandoned in 1904 when it was sold to the Great Western Railway for £2,000, and used as a branch of the Bristol and North Somerset Railway.

The Radstock branch
When the Radstock branch was constructed, it was intended to link it to the main line of the Paulton branch at Midford, which was at a lower level at this point. The Lock Fund created in 1802 was to have paid for the construction of the locks, but because there was little regular traffic on the branch, the company built one lock, an aqueduct over the Midford Brook, and a short tramway to bridge the gap. This contributed to the economic failure of the branch, and its replacement by a tramway in 1815. The tramway was laid along the former canal's towpath. It was single-line with passing places every 600 yards (549 m), and was originally laid using cast iron plates on stone block sleepers, but was relaid using wrought iron plates.Engineers and surveyors

This box moved up and down in the 60 ft (18 m) deep pool of water, which never left the lock. The box was demonstrated to the Prince Regent

Each Caisson would have had such a drain for maintenance purposes over the exit arch made to the same dimensions. The following extract from The Bath Herald Paper provides the details of the chosen sites.

, which were connected to the canal by tramroads.
On the northern side of Paulton basin was the terminus for the tramroad which served Old Grove, Prior's, Tyning and Hayeswood pits, with a branch line to Amesbury and Mearns pits. Parts of this line were still in use in 1873, probably all carrying horse drawn wagons of coal. The southern side of the basin served Brittens, Littleborrok, Paulton Ham, Paulton Hill, Simons Hill terminating at Salisbury Colliery. In addition the Paulton Foundry used this line. The entire line was disused by 1871 as were the collieries it served.

Excavations of the old stop lock showed that this had originally been a broad (14 feet (4 m)) lock that at some point was narrowed to 7 feet (2 m) by moving the lock wall. While some canal features are on private land, the towpath may survive in places as a right of way, while the later railway between Midford to Wellow is being surfaced to form part of National Cycle Route 24.
