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.
