…the most important technological change for the transportation of heavy goods in nineteenth-century India was not the arrival of the quick, expensive railway: it was the move from pack animals to carts pulled by two or four beasts in the first half of the century. This was the process historian Amalendu Guha calls ‘the bullock cart revolution’. Throughout the 1860s and 1870s railways found it impossible to compete not only with bullock carts, but also with human-powered river transport. Rowing boats along the Ganges and Jamuna won a price war with the railways over the cost of transporting heavy goods. Vessels powered by human beings were able to undercut steam vessels elsewhere.
There is a description of the book (which I have now ordered) here.
How did transport in Ireland compare? In the first half of the century, road transport using Scotch carts dominated carrying. Within about 55 miles of Dublin, eastward of Mullingar on the Royal and Tullamore on the Grand, canal carriers did little business except in the heaviest goods: the Scotch carts, each drawn by one horse and carrying about one ton, dominated the trade. But the Scotch carts relied on there being good roads, which in many cases required government intervention of one sort or another.
But rowing boats do not seem to have been serious contenders on Irish inland waterways. They might have been used on the Shannon, to tow canal boats, and the idea was mooted, but nothing seems to have come of it. The problem, I suspect, was that there was little or no trade: when it did arrive, it did so because the steamers created it. And the capital cost of a large pulling boat might have been beyond the means of a small-scale entrepreneur who might have been able to afford a cart.
On the other hand, vessels powered by sail retained certain markets, including traffic across the Irish Sea, until the middle of the twentieth century.
Much about Irish transport history remains unclear to me.
