City and South London Railway

The City & South London Railway (C&SLR) was the first deep-level underground "tube" railway in the world,[1] and the first major railway in the world to use electric traction. Originally intended for cable-hauled trains, the collapse of the cable contractor while the railway was under construction forced a change to electric traction before the line opened – an experimental technology at the time.

When opened in 1890, it served six stations and ran for a distance of 5.1 kilometres (3.2 mi)[2] in a pair of tunnels between the City of London and Stockwell, passing under the River Thames. The diameter of the tunnels restricted the size of the trains and the small carriages with their high-backed seating were nicknamed padded cells. The railway was extended several times north and south; eventually serving 22 stations over a distance of 21.7 km (13.5 mi) from Camden Town in north London to Morden in Surrey.[2]

Although the C&SLR was well-frequented, low ticket prices and the construction cost of the extensions placed a strain on the company's finances. In 1913, the C&SLR became part of the Underground Group of railways and, in the 1920s, it underwent major reconstruction works before its merger with another of the Group's railways. In 1933, the C&SLR and the rest of the Underground Group was taken into public ownership. Today, its tunnels and stations form the Bank branch and Kennington to Morden section of the London Underground's Northern Line.

Establishment

Arms of the City & South London Railway

In November 1883, notice was given that a private bill was to be presented to Parliament for the construction of the City of London & Southwark Subway (CL&SS).[3] The promoter of the bill and engineer of the proposed railway was James Henry Greathead who had, in 1869–1870, constructed the Tower Subway using the same tunnelling shield/segmented cast iron tube method proposed for the CL&SS. The railway was to run north from Elephant and Castle, in Southwark, south London, under the River Thames to King William Street in the City of London. The tracks were to be placed in twin tunnels 3.1 metre (10 ft 2 in) in diameter.[4]

The bill received Royal Assent as the City of London and Southwark Subway Act, 1884 on 28 July 1884.[5] Section 5 of the Act stated:

"The works authorised by this Act are as follows:-
"A subway commencing ... near ... Short Street at the ... junction ... with Newington Butts and terminating at King William Street ...
"The subway shall consist of two tubes for separate up and down traffic and shall be approached by means of staircases and by hydraulic lifts."

In 1886, a further bill was submitted to Parliament to extend the tunnels south from Elephant and Castle to Kennington and Stockwell.[6] This received assent on 12 July 1887 as the City of London and Southwark Subway (Kennington Extensions, &c.) Act, 1887,[7] allowing the construction of the extension to be added to the work on the original route, which had begun in 1886.[8] The tunnels on this section were of a slightly larger diameter of 3.2 m (10 ft 6 in).[4] Before the railway opened, a further bill received assent, granting permission to continue the line south to Clapham Common.[9] The act was published on 25 July 1890 as the City and South London Railway Act, 1890, also effecting a change of the company's name.[10]

Haulage and infrastructure

Like Greathead's earlier Tower Subway, the CL&SS was originally intended to be operated by cable haulage with a static engine pulling the cable through the tunnels at a steady speed.[11] Section 5 of the 1884 Act specified that:

"The traffic of the subway shall be worked by ... the system of the Patent Cable Tramway Corporation Limited or by such means other than steam locomotives as the Board of Trade may from time to time approve."

Trains were to be attached to the cable with clamps. These would be opened and closed at stations allowing the carriages to disconnect and reconnect without needing to stop the cable or interfere with the progress of other trains sharing the cable.[12] The additional lengths of tunnels permitted by the supplementary acts challenged the practicality of a cable-hauled system and before a solution could be found the cable contractor went out of business.[4] Given the small dimension of the tunnels, steam power, used on London's other underground railways, was not feasible for a deep tube railway and had been prohibited by the enabling Act. The solution adopted was electrical power provided via a third rail beneath the train. Although the use of electricity to power trains had been experimented with in the previous decade and small-scale operations had been implemented, the C&SLR was the first major railway in the world to adopt it as a means of motive power.[12] The system operated using electric locomotives built by Mather & Platt collecting a current at 500 volts from the third rail and pulling several carriages.[13] A depot and generating station were constructed at Stockwell.[14] The limited capacity of the generators meant that the stations were originally illuminated by gas.[15] The depot was on the surface and trains requiring maintenance were initially hauled to the surface via a ramp but a lift was soon installed.[16] In practice, most rolling stock and locomotives only went to the surface for major maintenance.

To avoid the need to purchase agreements for running under surface buildings, the tunnels were bored below roadways where construction could be carried out without charge.[4] At the northern end of the railway, the need to pass deep beneath the bed of the River Thames and the mediaeval street pattern of the City of London constrained the arrangement of the tunnels on the approach to King William Street station. Due to the proximity of the station to the river, steeply inclined tunnels were required to the west of the station. Because of the narrow street under which they ran, they were bored one above the other rather than side by side as elsewhere.[4] The outbound tunnel was the lower and steeper of the two. The tunnels converged immediately before the station, which was contained in one large tunnel and comprised a single track with platforms each side.[17] The other terminus at Stockwell was also constructed in a single tunnel but with tracks each side of a central platform.[18]

Opening

Kennington station, the only one of the original station buildings not substantially altered or replaced

The railway was opened officially by Edward, Prince of Wales (later Edward VII) on 4 November 1890.[19] It was opened to the public on 18 December 1890.[20] Initially, it had stations at:

The interior of a C&SLR padded cell carriage

The original service was operated by trains composed of an engine and three carriages. Thirty two passengers could be accommodated in each carriage[15], which was provided with longitudinal bench seating and sliding doors at the ends, leading onto a platform from which they could board and alight. It was reasoned that there was nothing to look at in the tunnels so the only windows were in a narrow band high up in the carriage sides. Gate-men rode on the carriage platforms to operate the lattice gates and announce the station names to the passengers. Due to their claustrophobic interiors, the carriages soon became known as padded cells.[21] Unlike other railways, there were no ticket classes or paper tickets; when the railway began operations, a single flat fare of two pence, collected at a turnstile, was charged for all passengers.[15] Despite the cramped carriages and competition from existing bus and tram services over its route, the railway attracted 5.1 million passengers in 1891, its first year of operation.[22] To alleviate overcrowding, the fleet of rolling stock was enlarged.[23]

Extensions to Clapham and Islington, 1890–1901

Shortly before it opened to the public, the C&SLR gave notice of its intention to submit another private bill to Parliament – this time to construct a new line from its northern terminus at King William Street towards Islington.[24] Due to the awkward arrangement of King William Street station, the extension was not to be connected directly to the existing running tunnels but was to be linked via a pedestrian subway through which passengers could make interchanges between the separate lines. The bill was rejected on the grounds that the extension failed to make a connection to the existing line.[25] In November 1891, the C&SLR published details of a revised bill for the extension to Islington.[26] The company had recognised the deficiencies of its King William Street station and, just a year after the line had opened, planned to construct a new pair of tunnels to bypass the problematic northern section.

Near to Borough station, the new tunnels would branch off and follow a new route via a new station to form an interchange with London Bridge mainline station. The tunnels would then pass to the east of London Bridge, then north through the City of London to The Angel, Islington. Following a delay, during which a Joint Select Committee reviewed the proposals of several new underground railways,[27] the City and South London Railway Act, 1893 was approved and received Royal Assent on 24 August 1893.[28] The Act also incorporated another bill of 1893[29] to grant an extension of time to build the southern extension to Clapham.[27]

Construction of the two authorised extensions was delayed while funds were raised and plans were finalised. Between 1895 and 1898, three further bills were put before Parliament to keep the permissions alive and obtain additional approvals:

The narrow central platform at Clapham Common with tracks on both sides dates from the 1900 extension.

The new tunnels permitted by the 1895 Act enabled the track layout at King William Street station to be modified to a single central platform with a track each side. This was opened as a temporary measure while funds for the extensions were raised. Finance was eventually obtained and construction proceeded so that the King William Street section closed and the first section of the northern extension opened on 25 February 1900,[20] with stations at:

The southern extension opened shortly afterwards on 3 June 1900,[20] with stations at:

Like the original Stockwell station and the rearranged King William Street station, Clapham Road and Clapham Common stations were constructed with a single station tunnel, in which a central platform was served by tracks on each side.[36]

Work continued on the rest of the northern extension. The City and South London Railway Act, 1900, approved on 25 May 1900,[37] gave permission to enlarge the station tunnel at Angel to a diameter of 9.2 m (30 ft)[38] [39] and the rest of the extension opened on 17 November 1901,[20] with stations at:

Extension to Euston, 1901–1907

Despite the technical innovations of the railway and the large passenger demand,[41] the C&SLR was not particularly profitable and the rapid series of extensions undertaken by the company aimed at improving profits had placed a strain on the finances. The dividends were low and declining (2⅛% in 1898, 1⅞% in 1899 and 1¼% in 1900) and the company had been accused of extravagance for the abandonment of King William Street station.[42] In an attempt to work around this poor reputation and make it easier to raise funds, the next bill for an extension of the line was submitted in November 1900 by a notionally separate company, the Islington and Euston Railway (I&ER),[43] albeit one that shared its chairman with the C&SLR.[44] The proposed railway was to run from the, as yet unfinished, C&SLR station at Angel to the mainline stations at King's Cross, St. Pancras and Euston. The I&ER bill coincided with a rash of other railway bills encouraged by the successful opening of the Central London Railway (CLR) in 1900 and was considered alongside these by another Parliamentary Joint Committee in 1901. The bill was approved,[45] but the time taken for the committee's review meant that it had to be resubmitted for the 1902 Parliamentary session.[46]

In the 1902 session, the bill was considered again but was subject to opposition from one of London's other underground railways, the Metropolitan Railway (MR), which considered the proposed extension to be a threat to its service between King's Cross and Moorgate. The I&ER also submitted a petition to allow the C&SLR to take over the powers of the railway if approved.[47] The committee reversed its earlier decision and rejected the bill.[48] In November 1902, the C&SLR submitted a bill in its own name for the Euston extension as well as the authority to take over the dormant powers of the C&BR.[49] At Euston, the railway would have an interchange with the planned but not yet built Charing Cross, Euston & Hampstead Railway (CCE&HR). The intention for C&BR powers was to adapt them to provide a new station at King William Street, which would have pedestrian subway connections to the C&SLR's Bank station and the Metropolitan District Railway's (MDR's) Monument station. A third pair of tunnels would be constructed under the Thames to connect with the original abandoned tunnels north of Borough station and then the C&BR route would be constructed as previously approved with connections to the existing C&SLR route at London Bridge and Oval.[50] This time, the bill was approved and received Royal assent as the City and South London Railway Act, 1903 on 11 August 1903.[51] Although the C&BR proposals were never used, the Euston extension was quickly built and opened on 12 May 1907,[20] with stations at:

Cooperation and consolidation, 1907–1919

By 1907, Londoners had seen the network of deep tube underground railways expand from the original C&SLR line of 1890 with its six stations to a network of seven lines serving more than seventy stations.[52] These companies, along with the sub-surface Metropolitan Railway and Metropolitan District Railway, criss-crossed beneath the city streets, competing with one another for passengers as well as with the new electric trams and motor buses. In several cases pre-opening predictions of passenger numbers had proven to be over optimistic. The reduced revenues generated from the lower numbers of passengers using the lines made it difficult for the operators to pay back the capital borrowed and pay dividends to shareholders.[53][54]

In an effort to improve their collective situations, most of the underground railways in London; the C&SLR, the CLR, the Great Northern & City Railway and the Underground Electric Railways Company of London Limited (UERL, which operated the Baker Street & Waterloo Railway (BS&WR), the Great Northern, Piccadilly & Brompton Railway (GNP&BR), the CCE&HR and the MDR) began, from 1907, to introduce fare agreements. From 1908, they began to present themselves through common branding as the Underground.[54] The Waterloo & City Railway, operated by the mainline London and South Western Railway, was the only tube railway that did not participate in the arrangement.

In 1912, the C&SLR submitted another bill for Parliamentary consideration seeking to increase its capacity by enlarging its tunnels to the larger diameter used for the tunnels of the more recently built railways. The enlarged tunnels would allow larger, more modern rolling stock to be used and this was also provided for in the bill.[55] A separate bill was published at the same time by the London Electric Railway (LER, a company formed by the UERL in 1910 through a merger of the BS&WR, GNP&BR and CCE&HR), which included plans to construct tunnels to connect the C&SLR at Euston to the CCE&HR's station at Camden Town.[56] Together, the works proposed in these bills would enable the CCE&HR's trains to run over the C&SLR's route and vice versa, effectively combining the two separate railways.

On 1 January 1913, the LER purchased the C&SLR, paying two shares of its own stock for three of the C&SLR's[57] – a discount reflecting the struggling financial position of the older company.[58] Both bills were enacted on 15 August 1913 as the City and South London Railway Act, 1913 and the London Electric Railway Act, 1913.[59]

The proposed extension and tunnel enlargement works were delayed by World War I and it was not until after the war that works could begin.

In February 1919, with the War over, the C&SLR submitted a new bill that included provisions for an extension of time for the tunnel enlargement works approved in the act of 1913.[60] The resulting act was passed on 19 August 1919 as the City and South London Railway Act, 1919.[61] In 1920, under special wartime provisions, The LER was granted an extension of time to carry out the works for its own 1913 act.[62] However; although the permissions to carry out the works had been renewed, the Underground companies were not in a position to raise the funds needed to pay for the works. Construction costs had increased considerably during the war years and the returns produced by the companies could not cover the cost of repaying borrowed capital.[63]

The projects were made possible when the government introduced the Trade Facilities Act, 1921 by which the Treasury underwrote loans for public works as a means of alleviating unemployment. With this support, the Underground companies were able to obtain the funds and work began on enlarging the tunnels of the C&SLR.

The tunnels were enlarged by removing several of the cast iron segments from each tunnel ring, excavating a void behind to the required new diameter and reinstalling the segments with additional packing spacers. The northern section of the C&SLR between Euston and Moorgate was closed from 8 August 1922, but the rest of the line remained open with enlargement works taking place at night.[20] A collapse on 27 November 1923 caused when a train hit temporary shoring on the incomplete excavations, filled the tunnel with soil.[20] The line was briefly operated in two parts, but was completely closed on 28 November 1923.[20]

The Euston to Moorgate section reopened on 20 April 1924, along with the new tunnels linking Euston to Camden Town.[20] The rest of the line to Clapham Common reopened on 1 December 1924.[20] At the same time as the tunnels were being enlarged, the stations were modernised, with longer platforms, a new tiling scheme on platform and passageway walls and new frontages to the surface buildings. Some stations also received escalators to replace the original lifts.

While the reconstruction works were underway, the C&SLR submitted a bill in 1922 that contained proposals to extend the line south from Clapham Common through Balham and Tooting to Morden in tunnel.[64] From Morden, the line was to continue on the surface to Sutton sharing part of the route of an unbuilt railway planned from Wimbledon to Sutton.

See Wimbledon and Sutton Railway for full details

The bill was enacted as the City and South London Railway Act, 1923 on 2 August 1923.[65] Parallel negotiations with the Southern Railway over the proposals curtailed the extension at Morden where a large new depot was also constructed. The Morden extension opened on 13 September 1926,[20] with stations designed by Charles Holden at:

Also on 13 September 1926, a further connection between the CCE&HR and the C&SLR was opened when tunnels were brought into service from the CCE&HR's Charing Cross station (now Embankment) to Kennington station rebuilt with four platforms. An intermediate station was also constructed at Waterloo. Thus fully integrated, combined services operated over the C&SLR and CCE&HR routes using the newly built Standard Stock trains. On tube maps the combined lines were shown in a single colour although the separate names continued in use into the 1930s.[66]

Move to public ownership, 1924–1933

Despite the modernisation of the C&SLR and other improvements made to other parts of the network,[67] the Underground railways were still struggling to make a profit. The Underground Group's ownership of the highly profitable London General Omnibus Company (LGOC) since 1912 had enabled the Group, through the pooling of revenues, to use profits from the bus company to subsidise the less profitable railways.[68] However, competition from numerous small bus companies during the early years of the 1920s eroded the profitability of the LGOC and had a negative impact on the profitability of the whole Group.

In an effort to protect the Group's income, its Managing Director/Chairman, Lord Ashfield, lobbied the government for regulation of transport services in the London area. During the 1920s, a series of legislative initiatives were made in this direction, with Ashfield and Labour London County Councillor (later MP) Herbert Morrison, at the forefront of debates as to the level of regulation and public control under which transport services should be brought. Ashfield aimed for regulation that would give the existing Group protection from competition and allow it to take substantive control of the LCC's tram system; Morrison preferred full public ownership.[69] Eventually, after several years of false starts, a bill was announced at the end of 1930 for the formation of the London Passenger Transport Board, a public corporation that would take control of the Underground Group, the Metropolitan Railway as well as all buses and trams within an area designated as the London Transport Passenger Area.[70] The Board was a compromise – public ownership but not full nationalisation – and came into existence on 1 July 1933. On this date, the C&SLR and the other Underground companies were liquidated.[71]

Legacy

The technologies of deep tube tunnelling and electric traction pioneered and proved by the C&SLR shaped the direction of subsequent underground railways built in London.[72] The C&SLR demonstrated that an underground railway could be constructed without the need to purchase large and expensive tracts of land for the shallow cuttings of sub-surface steam operated railways. Instead, it became possible to construct a tunnel at deep level without adversely effecting conditions on the surface. The C&SLR thus encouraged the construction of a network of underground railways in London – far larger than would have been the case otherwise.[73] The size and depth of the tunnels used on the deep tube lines does have drawbacks – the size of train carriages is limited and the lines suffer from overheating in the summer.

During World War II, the disused tunnels between Borough and King William Street stations were converted for use as an air-raid shelter, with entrances to the shelter situated at King William Street and at six sites south of the Thames (of nine planned.) .[74][75] In the 1960s the disused tunnels were used to assist the ventilation of London Bridge station and all of the entrances bar that at No. 9 London Bridge Street were infilled with concrete. It is now only possible to access the tunnels from Three Castles House. Most of the C&SLR's six original station buildings were rebuilt or modified during the improvements to the line in the 1920s or during more recent modernisations. Only the building at Kennington retains its original exterior and the dome over the lift shaft, a feature of all the original stations.
