Paisley Canal line

The Paisley Canal line, 1885

During the early years of the nineteenth century, Hugh Montgomerie, 12th Earl of Eglinton developed Ardrossan Harbour at a cost of more than £100,000: he intended for it to serve as a sea port to serve the nearby city of Glasgow, as the River Clyde was not navigable for large vessels at the time. In 1806, he obtained Parliamentary authority to construct the Glasgow, Paisley and Ardrossan Canal. Montgomerie held hopes that other businessmen and investors would quickly subscribe to his scheme; however, only £44,342 would prove to be forthcoming. While work did commence on the canal at the Glasgow end; it had only reached Johnstone by the time by which all of the raised money for the endeavour had been spent; in addition, the company had also borrowed considerable sums, when combined, debts of £71,209 had been accumulated. As part of financial reconstruction efforts, the canal's name was changed to the Glasgow, Paisley and Johnstone Canal.

Later on, Montgomerie's attention turned to building a railway at the Ardrossan end of the canal's intended route; these aspirations became the Ardrossan Railway. This too was built with the aim of connecting Ardrossan to Glasgow and, just as its predecessor had, it ran out of money during construction, having only reached Kilwinning and Eglinton's collieries in the vicinity. On 5 July 1865, the G&SWR was authorised by an Act of Parliament to acquire the canal, which it did so at a cost of £91,000; however, it had long since possessed a controlling stake in the canal company, having purchased its debt in connection with G&SWR's earlier acquisition of the Ardrossan Railway, with which the canal's financial affairs had been long intertwined.[1][2]

Early on, the G&SWR undertook to keep the canal operational and open to traffic, as well as to pay £3,471 annually to the canal company's proprietors.[3] At the time therefore, there had been no declared intention to use the physical infrastructure of the canal for railway-related purposes; however, at a shareholders' meeting held during 1879, the Chairman referred to a newspaper article which had made claims that the G&SWR held intentions to convert the canal into a railway line. At that time, there was extreme sensitivity among shareholders over what some saw as the directors' whimsical and expensive schemes, leading to the Chairman speaking out to deny the claim, stating: "That had not entered into the minds of any of the directors, nor was it thought of in the most remote manner, till they saw it in the newspaper." In the Chairman's own words, the suggestion of such a conversion: "was perfect nonsense".[4]

By this time, the Glasgow and South Western Railway (G&SWR) possessed an operational main line between Ayr and Carlisle; but the first section of the Ayr line was over the Glasgow and Paisley joint line. Under this structure, it was operated by a Joint Committee, which was answerable to both the G&SWR and its rival, the Caledonian Railway. This lack of sovereignty was a difficult enough prospect for the highly competitive railway politics of the era; but, as traffic developed, congestion on the busy line became a serious and obstructing issue which fuelled conflict. At that time, goods traffic was heavy and slow, thus both line capacity and service reliability were becoming heavily compromised by the high levels of traffic using the existing line.

During the 1881 Parliamentary session, a Bill was lodged by the G&SWR for the draining of the canal and conversion work to build a railway on its route: exactly the scheme to which the former Chairman had described as perfect nonsense only two years beforehand. On this occasion, there was no serious opposition to the proposal raised, thus an Act of Parliament authorising this work was passed.[3] However, this outcome had meant that the G&SWR had found itself in the position of having to raise money for the building of the new line, as well as for existing projects such as the quadrupling of the joint line and the extension of Gilmour Street station at Paisley simultaneously.

During 1881, the same year as the canal's conversion work been authorised by Parliament, it was permanently closed to traffic and drained in preparation for building the railway on top of its former route.[5] The canal had been built as a contour line, following exactly a particular altitude; in this manner, it had avoided the use of locks at the expense of having to adopt a circuitous route between its destinations. During the reconstruction works, many of the loops and sharper turns which had been taken by the course of the canal were eased, often via the use of earthworks, as the higher-speed railway was less tolerant of sharp curves but more able to accommodate the presence of mild gradients.

During March 1885, the first goods trains started running on the new line;[1] on 1 July 1885, it was also opened to passenger trains.[6] In addition to serving local trains, a number of long distance expresses made use of the route; reportedly, the best time achieved from St Enoch to Paisley Canal was 17 minutes, compared with 16 minutes to Gilmour Street on the joint line.[1]

During the following year, on 5 February 1886, the Potterhill branch of the Canal line opened; this was built to account for the expanding industrial importance of Paisley. Soon, a total of eight westbound and seven eastbound stopping trains were running each day on the Canal line; of these, five were extended to run onto or from Potterhill, while the remainder ran through to Johnstone. A triangular junction was built to provide access to the Potterhill line. The Potterhill branch would later formed the base of the Barrhead Branch.

During 1894-1895, construction work on the Canal line was focused upon the building of extensive carriage sidings at Bellahouston, as well as an engine shed at nearby Corkerhill. The availability of affordable land at these locations had rendered such schemes much more economical, but came at the expense of additional empty mileage.[1]

The main line was opened March 1885 to goods traffic, and on 1 July 1885 to passenger services. It was closed on 10 January 1983; and reopened from Shields Jn to Paisley Canal (new station) on 28 July 1990.

Blackhall Bridge 7 January 2015

The line crosses the White Water of Cart at Blackhall Bridge. This was originally an aqueduct, the River Cart Aqueduct, which had been built for the Ardrossan Canal between 1808 and 1810, under the direction of the famed civil engineer Thomas Telford. The contractor for the aqueduct's construction was John Simpson and the cost of construction was £5,440. It is a freestone masonry segmental arch of 88 ft 6in (27 m) span and a height over the water of about 30 feet (9 m). The bridge is probably the longest span masonry aqueduct of the canal age on a British canal, and one of the world's earliest bridges to carry a public railway. It had to be widened in order to carry the double track railway, the line also crosses the bridge at a slight skew because of the easing of the sharp canal curvature.[3][12]

Author David L. Smith recounts an anecdote illustrating the difficulty of working fast trains over the Canal Line:

In later years, as a driver, Coutts got no. 80, a Manson 4-4-0, and he had her a long while. One night he was on the 5.10 with her, 50 minutes non-stop for the 41.9 miles [from St Enoch] to Ayr; Felix Hill was firing to him. Well, some of the "Heid Yins" were going down to Turnberry Hotel for the weekend, and they were travelling in the Directors' Saloon, a vehicle which Mr. C Hamilton Ellis once described as of "more than imperial splendour". The G&SW men had no such reverence for it. They called it, crudely, and no doubt unfairly, "The Shebeen". Some economist at St Enoch thought that a bit of mileage might be saved by tacking "the Shebeen" on the back of the 5.10. Now the 5.10 in those days went out by way of Paisley Canal, a route which has about as much curvature per mile as the Darjeeling-Himalayan, and with only ten minutes allowed in which to cover the first 8¼ miles to Paisley, a driver hadn't much time to ponder over radii and centrifugal force.

Away they went, thunder-and-turf, out the Canal Road. Coutts took [the curve at] Saucel at about his usual [speed], and he slid the whole crowd in "The Shebeen" under the table. Paisley Canal station did the same; and so did Elderslie. Right out at the cow's tail and getting all the wag, the distinguished party had a pretty stormy trip all the way to Ayr, at which point the murder of Coutts was strongly advocated. But when they found that Coutts had actually lost a minute to Paisley, they began to think something must be wrong with the routing, so the 5.10 was altered to run via the Glasgow and Paisley Joint Line, which was at least straight.[13]

The main difference between the original and current routes into Glasgow after 1966 was the alteration of Shields Junction to head to Glasgow Central instead of St Enoch. This was due to the fate of St Enoch station, which was a victim of the Beeching cuts, having been closed on 27 June 1966 to passenger services and 5 June 1967 to goods and parcel trains; the station was demolished during 1975. Since then, the St Enoch Centre (which took its name from the former occupier of the site) has been built upon the same land as had been used by the old station. During 1966, Elderslie station was also closed and demolished in the following years.[8] Around the same time, the stations at Hawkhead and Paisley West were also closed.[8]

For a time, passenger services continued on the Paisley Canal line up until its full closure; these ran from Glasgow Central station to Kilmacolm, while occasional trains to the Ayrshire Coast Line (using Class 101, Class 107 and Class 126 diesel multiple units among others) were also run. During the line's latter years, as a cost reduction exercise, the signal boxes were only single-shift manned, resulting in the last train of the day being run around 7pm.

On 10 January 1983, the line between Elderslie and Kilmacolm closed completely, as well as between Elderslie and Shields Junction, to scheduled passenger services.[8][5]

Following the closure of passenger services, the tracks between Shields Junction and Elderslie Junction were used for another two or three years to enable heavy merry-go-round coal and iron ore traffic from Hunterston Ore Terminal, on the Ayrshire Coast Line, to bypass the main line between Elderslie Junction, Paisley Gilmour Street Station and Glasgow Shields Junction. There were also occasional passenger train diversions away from Paisley Gilmour Street due to works associated with the AyrLine electrification project. However, even this traffic was diverted onto the line through Paisley Gilmour Street, and the Paisley Canal line was closed completely to all traffic between Hawkhead and Elderslie, partly as a result of the resignalling scheme associated with the AyrLine electrification project resulting in the severing of the line at Elderslie. The section between Hawkhead and Shields Junction remained open to serve the oil depot.[5]

During 1986, the track between Elderslie and Paisley Canal station was lifted, and the land around Paisley Canal station, including the line and the goods yard, was sold on and was mainly redeveloped for housing.[8] The station building itself was converted for use as a restaurant,[8] while the station footbridge was demolished and the space between the platforms filled in. Much of the abandoned railway line beyond the original Paisley Canal station has since been developed into a cycleway and walkway operated by Sustrans.[8]

Plaque at Paisley Canal station commemorating the 1990 re-opening of the Paisley Canal branch line

On 27 July 1990,[8] the line between Shields Junction and Paisley Canal station was reopened to passenger traffic by Strathclyde Passenger Transport and British Rail. A new Paisley Canal station was constructed just to the east of the Causeyside Street bridge.

For this reopening, the intermediate stations located at Corkerhill, Mosspark and Crookston were also restored at the same time. Subsequent to the line's re-launch, new stations at Hawkhead (one platform) and Dumbreck (two platforms) have been opened. Most stations have only a single working platform.
