Two Reports addressed to the Liverpool & Manchester Railway Company, on the projected North Line of Railway from Liverpool to the Manchester, Bolton, and Bury Canal, Charles Vignoles and Joseph Locke, Liverpool, 1835, first edition. The reports were commissioned by the Liverpool & Manchester Board and document the proposals faced by the Liverpool and Manchester Railway for a second route between Liverpool and Manchester by a line to the north of the Liverpool & Manchester route. Neither Vignoles nor Locke was prepared to accept that constant slopes of 1½ to 1 proposed were suitable and both preferred their own requirement for a slope of 2 to 1 where depths exceeded 20 ft. They both concluded that the amount of earthwork would be vaster and cost considerably more than estimated by the promoters. The Liverpool & Manchester Railway Co used the reports in their objections during the Parliamentary proceedings and the Bill was defeated.
