section of the Caledonian main line left Carstairs station and ran north-east. For several years passenger trains from Carlisle divided at Carstairs; the Glasgow portion proceeded, and the Edinburgh portion reversed direction towards the capital. It is likely that goods trains too ran to Carstairs and remarshalled there. A cut-off line was constructed enabling direct running from Carlisle towards Edinburgh, but it was little used and it was soon closed. Later a shorter chord line was built having the same effect. The line continued past Cobbinshaw and Kirknewton, descending into Edinburgh in the valley of the Water of Leith. The terminus was at

Development after first construction

In its early years the Caledonian Railway sought to become dominant in large areas of Scotland by leasing nascent companies. It was able to do so by guaranteeing lease payments in perpetuity, which avoided any need for cash at the time, but heavily indebted the company later. It saw the best opportunities to the north of the central belt, and in Ayrshire. As the company matured, it encouraged local promoters to start construction of branch lines, taking them over by purchase if they were successful. The principal effect of this on the main line was the construction of a branch line from Gartsherrie to Greenhill Junction, there meeting the

, and giving access to Stirling and Perth. A first, short section of this branch used the route of the earlier Monkland and Kirkintilloch Railway (M&KR), another modernised coal railway. The M&KR was not brought into the Caledonian family, and through trains from the Caledonian at Motherwell towards Stirling used a rival company's track until nationalisation of the railways in 1948. A development that had not been foreseen was the emergence of the Monklands iron industry, which generated a huge demand for good quality iron ore and coal, and the Caledonian was fortunate that considerable reserves lay in areas served by it, or otherwise accessible over it. These factors led to a limited number of intermediate stations on the main line, and a concentration of effort elsewhere. There were no new branches off the main line at first, but the "Lanark" station was a considerable distance from the important Burgh, and local interests promoted a branch line to

was opened. The Caledonian acquired the line in 1865. The Portpatrick Railway had opened in 1861-1862 and the Caledonian worked it. This gave it access from Lockerbie to Stranraer and Portpatrick, enabling it to develop ferry services to the north of Ireland. It routed traffic from there to Glasgow and Edinburgh via Lockerbie, bringing considerable additional traffic to the main line. When the Portpatrick Railway was reconstituted into the

had intended to build an independent line to Carlisle from Gretna, but this was forbidden by Parliament during the authorisation process. The G&SWR was required to make a junction with the Caledonian main line at Gretna Junction, and to run over the line into Carlisle. That arrangement started in 1850, and the former G&SWR still operates, making the connection at Gretna Junction as before. All the other branches referred to in this section have closed, with the exception of the Lanark branch.


The main line from 1879

The first main line cemented the configuration of the Caledonian Railway route to England. It was enhanced by subsequent improvement of the route into Glasgow, as well as extension of the Edinburgh terminal named Princes Street, completed in 1870 and the expansion of goods facilities in Carlisle. The final development of the route had taken place by 1879, when the Glasgow terminal at Glasgow Central was opened. The station was considerably more convenient than the terminals previously in use. The original routing over the Wishaw and Coltness and the Glasgow Garnkirk and Coatbridge lines was now by-passed for main line passenger traffic, although still in use for local passenger traffic and considerable mineral usage. The Buchanan Street terminal was now focussed on passenger services to the Stirling line. At Carlisle the first passenger station remained in use, but the original goods facilities had been enhanced by the opening of a separate ''Viaduct'' goods station, and a route for goods and mineral trains passing the passenger station giving direct independent access from the Maryport and Carlisle Railway route; iron ore from Workington to the ironworks of the Monklands and become hugely significant by this time. The goods by-pass lines at Carlisle became very extensive and were jointly owned and operated by several railway companies.


After 1879

By 1879 the shape of the Caledonian main line was substantially developed. Most of the branches that left the main line directly had been opened by then. The principal subsequent developments were: * comprehensive suburban development in greater Glasgow, redoubled in the last decades of the twentieth century; * duplication of the route from Law Junction in to Glasgow serving ironworks that later became Ravenscraig Steelworks, and giving enhanced access northwards to freight marshalling facilities at Mossend Yard; * the opening of a branch line to

Development of passenger train services

In 1850, the passenger service on the main line consisted of five trains daily from Carlisle to Glasgow, of which three were expresses. Two gave daytime transits from London, the faster taking 12 hours 55 minutes. The fastest journey from Carlisle to Glasgow took 3 hours 30 minutes, and all the trains carried portions to Edinburgh detached at Carstairs, or gave connections to Edinburgh there. There was a limited Sunday service.''Bradshaw's General Steam Navigation and Railway Guide'', 3rd mo, (March) 1850, reprinted by Middleton Press, Midhurst, 2012, As train service patterns settled down later in the nineteenth century, the Caledonian main line carried important express trains, as well as local stopping trains. In contrast to the frequent regular-interval services of the present day, the train frequency was limited. In 1895 there were four daytime expresses northbound; the first left Euston at 5.15 a.m. Many trains divided at Carstairs with separate portions from there to Edinburgh and in some cases Perth and Aberdeen. There were two sleeping car trains to Glasgow and two to Aberdeen. All the daytime trains called at Beattock, and there were four all-stations stopping trains as well as some short workings. The fastest journey from Carlisle to Glasgow took 2 hours 10 minutes.''Bradshaw's General Steam Navigation and Railway Guide'', 12th mo, (December) 1895, reprinted by Middleton Press, Midhurst, 2011, By 1922 there were five daytime express trains. Local passenger business had declined and there was only one all-stations train running throughout the route, but several very short workings and some semi-fast trains. The 10.00 a.m. express from Euston arrived at Glasgow Central at 6.30 p.m.; it was not named, and conveyed through carriages from Birmingham. It required 2 hours 26 minutes from Carlisle to Glasgow, calling only at Motherwell "when required". There were several night trains to Glasgow and to the northern lines.''Bradshaw's General Railway and Steam Navigation Guide'', 7th mo, (July) 1922, reprinted by Guild Publishing, London, 1985 By 1938 there were still only four daytime through trains Monday to Friday, although there were considerably more summer Saturday trains, many of them going north to Stirling and beyond, and some originating from Liverpool. The stopping service on the route remained very thin indeed, although the Edinburgh line had more stopping trains. There were many more night trains, several of them seasonal, and many running to the north of Scotland. The 10.00 a.m. train from Euston was named ''The Royal Scot'' and took seven hours to Glasgow, and seven hours and five minutes to Edinburgh, advertised as conveying restaurant car to both terminals. The train called only at Carlisle intermediately.''Bradshaw's July 1938 Railway Guide'', reprinted by David and Charles (Publishers) Limited, Newton Abbot, 1969, From electrification of the main line by

and Glasgow Central, but Edinburgh was not a destination served from London by this route. Trains from Liverpool and Manchester combined at Preston and divided again at Carstairs, giving through journeys to Glasgow and Edinburgh. Beattock station had closed by this time so that only Lockerbie, Carstairs and Motherwell were served by main line trains to Glasgow, and only Haymarket by Edinburgh trains.

ways from 27 May 1962, when the Cathcart Circle, and Newton - Uddingston - Motherwell were operated electrically. Further electrification of the Hamilton circle, and to Lanark, followed and the main line southwards was being progressively wired, so that by the end of 1973 electric locomotives could be exchanged between Carlisle and Shields Depot, running for the time being via Kirkhill. From 6 May 1974 the Hamilton Circle and Lanark routes were fully available for electric passenger trains. (These trains ran to Glasgow Central High Level, as the Argyle Line had not yet been constructed.) Not all of the platforms at Glasgow Central were electrified at this stage, and when main line electrification was introduced, the remaining non-wired platforms had to be fitted. The southern sections of the West Coast Main Line were electrified in the period to 1969. In April 1970 authorisation was given for the electrification between Weaver Junction (in Cheshire) and Cleghorn Junction (to which the Lanark electrification had already been implemented). By July 1973 the line had been resignalled throughout, and from 7 January 1974 freight trains were electrically hauled between Kingmoor Yard at Carlisle and Mossend Yard. From 22 April 1974 passenger trains were electrically hauled throughout between London and Glasgow.J C Gillham, ''The Age of the Electric Train'', Ian Allan Limited, London, 1988,


Modern use of the Caledonian main line

While the term ''Caledonian main line'' has no authoritative present-day definition, it is generally taken to mean the main line between Carlisle and Glasgow and Carstairs and Edinburgh. That is consistent with the first main line from Carlisle to Garriongill Junction, then following the Clydesdale Junction Railway route to Gushetfaulds, just outside South Side station, and then the later short line Glasgow Central station. The Edinburgh section runs from Carstairs to Edinburgh Waverley station; the final section of the original line to Princes Street was closed and trains diverted to Waverley. The route is now the northern section of the

, and carries a heavy passenger and freight service.


Current operations

At the present day the main line has a heavy long-distance passenger service to London, Birmingham and Manchester. Significant freight traffic also runs over the line. The Carstairs to Edinburgh line carries a considerable long-distance passenger service, although London to Edinburgh is not realistically dominant now, compared to the East Coast main Line service. In the Edinburgh and Glasgow travel-to-work areas there is a heavy suburban passenger service. Notable among these is the Argyle line service which runs from Lanark to North Clyde destinations through the Argyle line in Glasgow. Numerous other suburban routes operate in the greater Glasgow and Edinburgh conurbations.


Gradients

When the main line was conceived, there were misgivings about the capacity of the locomotive power of the day to handle trains over the heavy gradients approaching Beattock summit. By the time the line was opened, the technology of locomotive design had improved, and locomotive haulage was practicable. Nonetheless Beattock summit remained a significant operational limitation, and the provision of assistant engines for all but the lightest trains was routine from Beattock station to the summit throughout the era of steam traction. Leaving Carlisle, gradients were moderate until just before Gretna, from where a climb of 1 in 193 - 1 in 200 started as far as Castlemilk, beyond Ecclefechan. A slight decline then followed to Nethercleugh, where the climb resumed, stiffening again to 1 in 202 after Wamphray. At Beattock the serious climbing started with a gradient of 1 in 88 increasing to 1 in 74 for ten miles to Beattock Summit. A short fall of 1 in 89 for two miles to Elvanfoot followed. From there however the descent was more gentle and longer, at a typical gradient of 1 in 240 although with several short steeper sections. This reached as far as Carstairs, after which an eight-mile climb followed. There then followed a stiffer descent of up to 1 in 102 for sixteen miles to Uddingston. From there moderate undulations led to Glasgow Central station. The Carstairs to Edinburgh line had difficult gradients too. From Carstairs there was a climb of 1 in 225 stiffening to 1 in 97 as far as Cobbinshaw (eleven miles) then descending at 1 in 100 for five miles, slackening to 1 in 143 almost continuously as far as Edinburgh.''Railway Gradients of the British Main-Line Railways'', the Railway Publishing Company, London, 1947
