The '''Glasgow, Paisley and Ardrossan Canal''', later known as the '''Glasgow, Paisley and Johnstone Canal''', was a canal in the west of Scotland, running between Glasgow, Paisley and Johnstone which later became a railway. Despite the name, the canal was never completed down to Ardrossan, the termini being Port Eglinton in Glasgow and Thorn Brae in Johnstone. Within months of opening, the canal was the scene of a major disaster.

==Construction==
The canal was first proposed by Hugh Montgomerie, 12th Earl of Eglinton in 1791. He wanted to connect the booming industrial towns of Glasgow, Paisley and Johnstone to his new deep sea port at Ardrossan and his Ayrshire coal fields. His fellow shareholders included William Dixon of Govan who wished to export coal from his Govan colliery. The Earl had spent £100,000 on creating Ardrossan's harbour and intended to make it the principal port for Glasgow. Interest was also shown by Lord Montgomerie and William Houston who would also benefit from the canal passing through their lands and connecting their own coal and iron mines to nearby industrial consumers. In this pre John Loudon McAdam period, the roads around Lanarkshire, Renfrewshire and Ayrshire were not suitable for heavily loaded traffic. The other alternative route, up the Clyde river estuary to Glasgow, was not navigable by large ships as the river was too shallow.

Engineers John Rennie, Thomas Telford and John Ainslie were employed to design the canal, survey a route, and estimate the costs. The original design was in three parts. The first section would be a contour canal of about 11 mile in length. Following the land, a contour canal is entirely level and requires no locks or lifts making navigation quick and easy. Contour canals require only a small water supply since no water is lost to locks, but this method of construction would make the canal longer than it need have been. The second section would see a series of 8 locks lift the level up to a summit near Johnstone. The third and last section would use 13 locks to bring the canal down to sea level at Ardrossan Harbour. When complete the canal have been just shy of 33 mile long. The dimensions of the cutting were to be 30 ft broad at the top and at bottom, 18 ft. The depth was to be 4 feet 6 inches.

The Company of the proprietors of the '''Glasgow, Paisley and Ardrossan canal''' was incorporated by an Act of Parliament which received Royal assent from George III on the 20 June 1806. This bill allowed for funding to be raised by the sale of two thousand eight hundred shares of £50 each, a total of £140,000, of which the proprietors, the Earl of Eglinton, Lord Montgomerie and Lady Jane Montgomerie subscribed £30,000.

Construction began in 1807 and the first boat, the passenger boat, ''The Countess of Eglinton'', was launched on the 31 October 1810. The passenger service initially only ran between Paisley and Johnstone. The full length to Glasgow's Port Eglinton was complete sometime in 1811. The original plans to extend the canal to Ardrossan were soon suspended. The costs of completing the first 11 mile contour canal had consumed all the available funds – the initial estimates having been grossly understated. Further estimates indicated that £300,000 additional funding would need to be secured to complete the project. Hugh Montgomerie, 12th Earl of Eglinton, had already spent £100,000 on a separate project to build a sea harbour at Ardrossan, at the proposed terminus of the canal. The Harbour project would eventually be competed by his grandson, the 13th Earl, for a total cost of £200,000. Attempts were made to raise extra funds but other major investors, such as William Houston, were reluctant to invest as the canal already linked his own coal and iron mines, around Johnstone, to Glasgow and Paisley.

==Operation==

The canal ran from Port Eglinton; and an inn was built there in 1816. A wharf was built on the north bank of the River Cart near Crookston Castle; and canal basins provided at Paisley and Johnstone.

===Passenger traffic===
The canal became a popular service for passenger transport.

In 1830, long, and shallow wrought iron canal boats began to run regularly, conveying about sixty passengers a distance of 12 mile, at an average rate of 8 mph, stoppages included. The boats reached speeds of 10 mph, and although 14 journeys were made each day, no damage was caused to the canal banks by their wash.

This development was copied widely in the canal world, where they were known as swift boats or fly-boats, but it took the young John Scott Russell to explain the phenomenon and show its limits.

The Paisley canal passage boats were 70ft long and 6ft wide. With 90 passengers on board their draft was 19.25 inch. The hull was constructed of light iron ribs and thin metal plates. The cabin was covered with oiled cloth. They covered the 7.75 mile between Glasgow and Paisley in 50 minutes. They were towed by teams of two horses which were changed every 4 mile.

Fast, narrow, iron hulled boats of an innovative design and pulled by 6 horses allowed 80 to 100 passengers to travel at a rate of 10 miles per hour. An extraordinary speed at the time. The price of just one penny per mile for first class and three farthings per mile for the second class cabins was also highly competitive – less than half that charged by the new Liverpool Railway. At its height, in 1834, boats carried 397,375 passengers during the year. In July and August of that year, 2,500 passengers were recorded in just ''one day''.
====Deaths on the canal====
A few months before the canal saw its first traffic, poet Robert Tannahill drowned himself during a bout of depression, by throwing himself into a deep pit which carries the water of a stream down to a culvert under the canal. This came to be known as Tannahills Hole. A group of his poems had just been rejected by an Edinburgh publisher. He was well known for periods of depression. He burned many of his writings at this time. His body was found on 17 May 1810 in the Candren Burn tunnel under the canal.

Shortly after the canal's opening, the '''Paisley canal disaster''' took the lives of 84 people, 52 males and 32 females. Saturday 10 November 1810 was the Martinmas Fair. Many people, with the day off work, took the opportunity to travel the short distance of 6 mile by canal between Paisley and Johnstone. As ''The Countess of Eglinton'' docked at the Paisley wharf, there was a rush of people trying to get onto the boat. At the same time, people from Johnstone were attempting to disembark. Despite the attempts of the boat men to push off again, the weight of people pushing onto the boat caused it to suddenly overturn, throwing many passengers into the cold water of the wharf.

Even though the wharf was only 6ft deep, the coldness of the water and the sheer sides of the Dike (construction)|embankments compounded the problem that few people of the time could swim. 85 people died in this disaster.

===Freight traffic===
Freight also made a significant part of the traffic on the canal. Basin dues were set at 2 pence per ton. Stone, dung and earth were charged at 2 pence per mile per ton; coal, coke culm and lime were 3 pence per mile per ton; Bricks, tiles, slates, orers, iron and metal were rated at 5 pence per mile per ton; and all other goods were charged 2 pence per mile per ton.

===Profitability===
The construction costs were so high that the canal never made an issue of dividend on its shares. Even after 20 years of operations, the accounts showed an outstanding debt of £71,208, 17 shillings and 6 pence.

===Canal versus railway===
In 1827, a second bill passed parliament and gained Royal Assent on 14 June. This bill allowed for the financing and construction of a railway from the Johnstone canal basin to Ardrossan. This railway was to have been 22 mile and 3 furlongs long. Parliament dictated that due to the failure to complete the canal past Johnstone, that work on the railway should be started at the Ardrossan harbour end. The line did not progress past Kilwinning before running out of funds. The railway, owned and operated by the canal company, was built to the Scotch gauge of 4 feet 6 inches (1,422 mm). It used pairs of horses to pull carriages of up to 22 people each. The fares were initially 1 penny per mile but in 1837, due to the application of a government duty, the fare was raised to 8 pence per 6 mile. In the three years preceding September 1839, the railway transported an average of 30,000 people each year. Apart from passengers, the main freight was coal form Eglinton's mines.

The dredging of the River Clyde and other navigation improvements, allowing ships to sail directly to the centre of Glasgow, meant Eglinton's dream that, "Ardrossan would be to Glasgow what Liverpool is to Manchester." would not be fulfilled.

A second railway line was opened, in 1840, by the Glasgow, Paisley, Kilmarnock and Ayr Railway Company (GPK&A), in direct competition with the canal. This new railway linked with the [[Ardrossan Railway]] near Kilwinning and later purchased the Ardrossan Railway, the railway company's debts and the harbours. The canal continued to compete with the railways for many decades, but in 1869, was purchased by the Glasgow and South Western Railway Company (the successor to GPK&A). In 1881, an Act of Parliament closed the canal. Much of the route was used to construct the Paisley Canal railway line.

==Conversion to a railway==

===The Ardrossan Railway===
In the 1820s the canal company planned to build a railway between Johnstone and Ardrossan to finish the link. They raised further capital and started building the railway from Ardrossan; reaching [[Kilwinning]] before running out of money. In the 1830s they planned to turn their canal into a railway and complete the link from Kilwinning to Johnstone; but allowed the scheme to fold. In the 1840s they split off their railway to form a separate company, the [[Ardrossan Railway]], and transferred their debt to the new company.

===Closure of the canal===
The canal was purchased in 1869 by the Glasgow and South Western Railway Company. In 1881, an Act of Parliament closed the canal. Much of the route was used to construct the Paisley Canal Line. This line still uses the River Cart Aqueduct (which it crosses at a skewed angle). This makes the former aqueduct the world's oldest railway bridge that is still in active use.

===Closure and partial reopening of the Paisley Canal Line===
The Paisley Canal railway line closed to passengers in 1983. The rails between Elderslie and the original Paisley Canal Station were uplifted in 1986; and the station became a steakhouse. In 1990, passenger services resumed on the section from Glasgow Central railway station to a new Paisley Canal railway station. Much of the abandoned track bed beyond Paisley has now been developed into a cycle and walkway operated by Sustrans.

Short sections of the original canal can still be seen at the Millarston and Ferguslie Mills area of Paisley. Houses in Tenenter Way and Cropton Grove face across the remnants. Traces of the old canal are also visible in fields between Hawkhead and Rosshall.
