Before the Kilsyth and Bonnybridge Railway Kilsyth and Bonnybridge had both become important industrial centres during the nineteenth century; the proximity of the
Forth and Clyde Canal as a transport medium facilitated the development of industry, and coal mining and iron smelting had become particularly dominant. The Baird Brothers of Gartsherrie were especially prominent in Kilsyth, and they built a considerable network of mineral tramways serving their pits and ironworks. Although the
Edinburgh and Glasgow Railway had opened in 1842, its route lay some distance to the south, and across the Forth and Clyde Canal. The first town in the district reached by a railway was Denny, served from the east in 1858: the
Scottish Central Railway opened its branch to the town, from Larbert Junction. In 1878 the nominally independent
Kelvin Valley Railway was opened, running from Kilsyth to a junction with the Campsie Branch of the
North British Railway, successor to the Edinburgh and Glasgow Railway, and giving access for passengers and minerals to Glasgow over that company's lines. The following year a second section of the Kelvin Valley line was opened, running to Maryhill on the north-west margin of Glasgow, and giving access there over the
Stobcross branch of the North British Railway to the new dock at Stobcross, soon to be named ''the Queen's Dock''.
Authorisation The industrial potential of the tract of land between Kilsyth and Denny was attractive for exploitation. At this period there was intense rivalry between the North British Railway and the
Caledonian Railway, and any proposed construction into the competitor's territory might result in hostile and costly reprisals. At length an independent concern was promoted to build a line closing the gap. The Kilsyth and Bonnybridge Railway was authorised by the '''''' (
45 & 46 Vict. c. clxxxvi) on 10 August 1882, with capital of £130,000. The line was to run from the Kelvin Valley Railway at Kilsyth to Bonnywater Junction on the Caledonian's Denny branch. Evidently the proprietors had second thoughts, for in 1885 they decided to abandon the project. However they again changed their mind and continued with the construction. Although the terrain was relatively easy, the line was not constructed speedily, and in fact the Caledonian Railway built a short branch line to Bonnybridge in the meantime, opening in 1886. However the Caledonian's Bonnybridge terminus was on the south side of the Forth and Clyde Canal, limiting its usefulness. The Caledonian also owned the Forth and Clyde Canal at this time. The canal ran parallel to the railway, and the Caledonian went to considerable lengths to arrange mineral line connections to the canal, to facilitate its use by mining companies, providing stiff competition for the railway. and obtained Parliamentary powers to do so, but business picked up a little and they did not proceed with the closure. In 1908 the independent staffing of the stations ceased and the railway was staffed by the NBR and the Caledonian, working together. Following the
Railways Act 1921, the K&BR ended its independent existence and the line became jointly operated between the new
London and North Eastern Railway (LNER), as successor to the North British Railway, and the
London Midland and Scottish Railway (LMS) as successor to the Caledonian Railway. Motor bus services and improved roads encouraged the development of efficient bus services in the 1920s and use of the passenger trains declined steeply. Passenger services were withdrawn on 1 July 1935. As the mines closed freight traffic also declined and the line was closed in stages. The last section to close was between Kilsyth and Banknock, on 4 May 1964. ==Topography==
