The Lanarkshire coal lines In the closing years of the 18th century, the pressing need to bring coal cheaply to Glasgow from the plentiful
Monklands coalfield had been met by the construction of the
Monkland Canal, opened throughout in 1794. This encouraged development of the coalfield, but dissatisfaction at the monopoly prices said to be exacted by the canal led to the construction of the
Monkland and Kirkintilloch Railway (M&KR), Scotland's first public railway; it opened in 1826. Development of the use of blackband
ironstone by
David Mushet, and the invention of the
hot blast process of
iron smelting by James Beaumont Neilson in 1828, led to a huge and rapid increase in iron production and demand for
iron ore and coal in the
Coatbridge area. The industrial development led to the construction of other railways contiguous with the , in particular the
Garnkirk and Glasgow Railway and the
Wishaw and Coltness Railway. These two lines worked in harmony, merging to form the Glasgow, Garnkirk and Coatbridge Railway in 1841, and competing with the and its allies. All these lines used the local track gauge of , and they were referred to as "the coal lines"; passenger traffic was not a dominant activity.
English railways During this period, the first long-distance railways were opened in England; the
Liverpool and Manchester Railway, the first intercity line, opened in 1830 and was an immediate success. It was quickly followed by the
Grand Junction Railway in 1837, the
London and Birmingham Railway in 1838 and the
North Union Railway reaching
Preston in 1838, so that London was linked with the Lancashire and West Midlands centres of industry.
Connecting Scotland and London It was clearly desirable to connect central Scotland into the emerging network. At first it was assumed that only one route from Scotland to England would be feasible, and there was considerable controversy over the possible route. A major difficulty was the terrain of the
Southern Uplands: a route running through the hilly lands would involve steep and lengthy gradients that were challenging for the engine power of the time; a route around them, either to the west or the east, involved much lengthier main lines, and made connection to both Edinburgh and Glasgow more problematic. Many competing schemes were put forward, not all of them well thought out, and two successive government commissions examined them. However, they did not have mandatory force, and after considerable rivalry, the Caledonian Railway obtained an authorising
act of Parliament, the '''''' (
8 & 9 Vict. c. clxii), on 31 July 1845, for lines from Glasgow and Edinburgh to Carlisle. The share capital was to be £1.8 million (equivalent to £ today). The Glasgow and Edinburgh lines combined at
Carstairs in
Clydesdale, and the route then crossed over
Beattock Summit and continued on through
Annandale. The promoters had engaged in a frenzy of provisional acquisitions of other lines being put forward or already being constructed, as they considered it was vital to secure territory to their own control and to exclude competing concerns as far as possible. It was not the only Anglo-Scottish route; the
North British Railway opened its coastal route between Edinburgh and
Berwick-upon-Tweed on 22 June 1846, forming part of what has become the
East Coast Main Line. The
Glasgow, Paisley, Kilmarnock and Ayr Railway had opened in 1841 with the declared intention of reaching Carlisle by way of
Dumfries; it did so in 1850, changing its name then to the
Glasgow and South Western Railway.
The main line The main line was opened from Carlisle to
Beattock on 10 September 1847, and throughout between Glasgow and Carlisle on 15 February 1848. A continuous railway route between Glasgow and London existed for the first time. (It had been possible to travel via Edinburgh and
Newcastle upon Tyne since 1846, but this involved crossing the
River Tweed at Berwick by road, and the
River Tyne at Gateshead / Newcastle by congested road bridge or ferry.) The Caledonian Railway's Edinburgh line from Carstairs opened on 1 April 1848. The terminal at Edinburgh was at
Lothian Road. Glasgow was reached over the Glasgow, Garnkirk and Coatbridge Railway (successor to the
Garnkirk and Glasgow Railway), and the
Wishaw and Coltness Railway, which the Caledonian had leased from 1 January 1847 and 1 January 1846 respectively. The Glasgow station was the
Townhead terminus of the Glasgow, Garnkirk and Coatbridge Railway. Handsome dividends continued to be paid, but it was not until March 1853 that the dividend was paid wholly from revenue.
South Lanarkshire: mainly mineral traffic If the Caledonian Railway had been formed as an intercity trunk line, its attention was early on turned to other demands. Local interests in
Lanark promoted a branch line to their town, opening in 1855. Coal owners in
South Lanarkshire pressed for a railway connection, and the
Lesmahagow Railway was formed by them, opening in 1856. It was later absorbed by the Caledonian, but other lines followed in the sparsely populated but mineral-rich area. As new coal mines opened, so new branches were needed, connecting
Coalburn,
Stonehouse,
Strathaven,
Muirkirk and
Darvel and many other places, with new lines built right up until 1905. When the coal became exhausted in the second half of the 20th century, the railways were progressively closed; passenger traffic had always been light and it too disappeared. Only the passenger traffic to the Lanark and
Larkhall branches remain in operation.
North Lanarkshire In
North Lanarkshire, the
North British Railway was a keen competitor, having taken over the
Monkland Railways. The area contained the rapidly-growing iron production area surrounding
Coatbridge, and servicing that industry with coal and
iron ore, and transport to local and more distant metal processing locations, dominated the Caledonian's activity in the region. The
Rutherglen and Coatbridge line, later linking
Airdrie, and the
Carfin to Midcalder line were routes with significant passenger traffic. Many lines to coal and iron ore pits further east were built, but serving remote areas the lines closed when the mineral extraction ceased. ==Developing the network: to 1880==
