The Modernisation Plan failed to successfully redefine what the purpose of the railways was. British Railways remained bound by the Railway and Canal Traffic Acts which obligated it to provide carriage for virtually any type of goods, regardless of quantity (large or small) between any two stations on the network, at set and published rates. This legislation dated back to the 19th century to prevent the railways abusing their monopoly as the sole practical long-distance transport provider for much of the country, but the growth of road transport had left the railways locked into a highly disadvantageous position. Road freight operators had no legal restrictions and could turn down work that was uneconomic, which BR could not, and could easily undercut BR's carriage rates which the railway could not alter without legal consent.
