Forth and Cart Canal
The Forth and Cart Canal was a short link canal which provided a short cut between the Forth and Clyde Canal, at Whitecrook, and the River Clyde, opposite the mouth of the River Cart. It was intended to provide a transport link between the town of Paisley, the Firth of Forth and Port Dundas, Glasgow, without having to go via Bowling, some downstream on the Clyde. The Forth and Cart Canal was closed in 1893. Railway works destroyed most of it soon afterwards. The Cart navigation. An Act of Parliament obtained in 1753 authorised improvements to  the White Cart Water, to make it navigable, and so assist the developing cotton industry in Paisley. The works included making the channel straighter and deeper. A new road bridge had been built at Inchinnan in 1787, after which Paisley Town Council obtained a second Act of Parliament, to authorise the construction of a new navigable cut, which would pass under the Turn Pike road (now the A8). Work started on 23 August 1787, and was expected to be completed within a year. With the anticipated building of the Forth and Cart Canal, further work was carried out in 1835  to improve the harbour facilities at Paisley. There were plans to make it much deeper and wider in the 1880s, so that ocean-going ships could reach Paisley, but although the work was declared complete on 25 May 1891, the first ship to attempt to use the river ran aground on the opening day, and the scheme was later abandoned. The River Cart and the White Cart Water provided a navigable waterway between the River Clyde and the centre of Paisley. The Forth and Cart Canal. The idea of a direct connection between the Cart Navigation and the Forth and  Clyde Canal had first been suggested by Hugh Baird in 1799, but no further action had been taken. When the Forth and Cart Canal was promoted in the 1830s, it essentially revived Baird's plan, in the hope that it would provide a better route between Paisley and the Firth of Forth than the alternative which went via Port Eglinton and Port Dundas. Port Dundas was on the north bank of the Clyde, at the end of the Glasgow Branch of the Forth and Clyde Canal, where it joined the Monkland Canal, while Port Eglinton was only a short distance  away on the south bank, and was the terminus of the Glasgow, Paisley and Johnstone Canal. There was no waterway between them and so goods had to be transferred by road. It was also expected that coal from Coatbridge would reach Paisley via the Monkland Canal, the Forth and Clyde, the proposed new canal and the Cart Navigation. It would save water on the Forth and Clyde, as smaller boats could pass down the link, rather than using the larger locks to the west, where the Forth and Clyde joined the River Clyde. The Forth and Cart canal was authorised  by an Act of Parliament in May 1836 and was completed in 1840. It joined the River Clyde almost opposite the mouth of the River Cart and joined the Forth and Clyde Canal at Whitecrook. It had three locks which were long and wide, limiting vessels to that size. Although the Forth and Clyde Canal obtained an Act of Parliament to allow it to take over the Forth and Cart in 1842, the transfer did not take place for another 13 years. By then, revenue was only £325 per year, and costs, which included interest on the debts from  the construction of the canal, exceeded this amount by £17. The canal was in a poor state, and it was estimated that £3,100 needed to be spent on it to return it to good order. The annual traffic was around 40,000 tons, as the railways now supplied the coal that Paisley used. The Forth and Clyde estimated that they made £739 per year from trade which passed from the Forth and Cart to their canal, and therefore offered to buy it for £6,400. If traffic exceeded 90,000 tons, the original proprietors would receive an extra penny  (0.4p) per ton. Although the payment would not clear the debts, and the likelihood of traffic increasing sufficiently to generate the tonnage payments was slight, the committee had little option but to accept. It was taken over by the Forth and Clyde Canal in 1855; and, together with the Forth and Clyde Canal and the Monkland Canal, was taken over by the Caledonian Railway in 1867. The Forth and Cart Canal was closed in 1893 as it was unprofitable. Remains of the canal. The closure of the canal provided an opportunity for the Glasgow - Clydebank railway, which brought workers from  Glasgow to the adjacent Thompson shipyard, to extend the line to Dalmuir. This line opened in 1896, and destroyed the first section of the canal. By 1897, there was a small section of canal at the northern end, which ended where a railway siding of the Glasgow, Yoker and Clydebank Railway crossed it. It had been shortened by the construction of another railway siding by 1919, although the towpath bridge was still evident. By 1937, there was no trace of the north end, as an employment exchange had been built over it. At the south end, the canal was truncated  just below the first lock, where the Lanarkshire and Dunbartonshire Railway crossed it. It remained in this state in 1919, but by 1939 had been reduced by half. A small part of it was still evident in 1985, but is no longer so. Despite its having been closed for over 100 years, the Environmental Statement for the construction on a new junction on the M8 motorway noted that the course of the canal was still clearly visible to the eastern edge of the shipyard site, and concluded that much of it probably still existed. A subsequent planning application for the  development of the shipyard site stated that although it had been intended to reinstate a short section of the canal as a water feature, investigation had shown that there were no substantial remains of the canal left, and the planning restrictions that protected the line of the canal were rescinded.
