The London Underground 1972 Stock is a type of rolling stock used on the London Underground. The 1972 Stock was originally ordered to make up the shortfall in trains on the Northern line's 1959 Tube Stock fleet, but is currently used on the Bakerloo line. Following the withdrawal of the 1938 Stock-based British Rail Class 483 EMUs from the Isle of Wight in 2021, the 1972 Stock are now the oldest trains in regular passenger service in the United Kingdom. A total of 63 seven-car trains were built in two separate batches.

Construction

A total of 441 cars were built by Metro-Cammell at Washwood Heath, in two batches: the 1972 Mark I Stock comprised 90 driving motors (DM), 90 trailers (T) and 30 uncoupling non-driving motors (UNDM), to form 30 seven-car trains; the 1972 Mark II Stock was 33 seven-car trains (99 DM, 99 T and 33 UNDM).^[3]

In the early 1970s, the 1938 Tube stock on the Bakerloo and Northern line was life-expired and due for replacement. Tentative designs for a new Northern line fleet were abandoned when the go-ahead was given for the Piccadilly line to be extended to Heathrow Airport. That required a totally new fleet of trains to replace the 1959 stock then in use. The plan was made to transfer the 1959 trains to the Northern, to allow the worst of the 1938 stock there to be scrapped, but there were only 76 1959 stock trains, and the Northern line needed more than that to operate. Originally, it was planned to refurbish around 30 of the 1938 trains, but this was scrapped in favour of 30 new trains of the 1972 Mark 1 Tube stock.

The 1972 Tube stock was ordered in a hurry, so there was no time to create a new design; the trains were based on the 1967 Tube stock on the Victoria line. Although almost identical looking, the 1972 trains were conventionally operated with a guard and door controls in the rear car, and were not compatible with 1967 Tube stock. In later years some surplus 1972 Mark 1 cars were adapted to run with the 1967 trains on the Victoria line, being coupled in the middle due to the lack of ATO equipment.

A further 33 trains of 1972 Tube stock were ordered to provide service on the Northern line. The 1972 Mark 2 stock had slightly different interiors with a dark blue seating moquette, unlike the red and grey on the earlier 1967 and 1972 cars. The biggest external difference was that the doors were painted red, with a London Transport roundel on the side of the carriages, rather than the Johnston lettering.

The 1972 Mark 2 trains first operated on the Northern line alongside the 1972 Mark 1 trains. From the late 1970s, they were gradually transferred to the Bakerloo line and operated alongside the 1938 Stock until they began operating on the Jubilee line when it opened in 1979. With the introduction of the first batch of 1983 stock on the Jubilee line in 1984, half of the 1972 Mark 2 trains were displaced back to the Northern line. After the introduction of a second batch of 1983 Stock on the Jubilee in 1987, all 1972 Mark 2 trains on the Jubilee and Northern lines were gradually converted to OPO and transferred to the Bakerloo line to displace the 1959 stock, where they remain in service.

In 1989, several Northern line Mark 1 units were painted in experimental liveries, and three trains were internally refurbished, before the refurbishment work was stopped because of the decision to order a new fleet. 3227 and 3518 were painted with blue doors and a white body, 3204 and 3522 were painted with a blue and white body, and 3202 and 3523 were painted in what would become a corporate livery. The earlier 1972 Mark 1 stock on the Northern line was replaced by 1995 Stock in 1999. After being withdrawn from the Northern line, a few cars of 1972 Mark 1 stock were converted to run with 1967 and 1972 Mark 2 stock in service on the Victoria and Bakerloo lines.

A further two trains were converted to be compatible with the Mark II type, and these now run on the Bakerloo line. One ex-Northern line set (3229) was based at the now-closed Aldwych station, for use in films until being sent to Ealing Common Depot in November 2021 and then Ruislip depot a month later. Another Mark 1 unit in a trial livery was sent to Acton Works to be used for shunting. One three-car unit (unit 3511)^{[ citation needed ]} used to reside at Hainault depot until October 2018, where cars 4511 and 3411 had moved to Acton Works. The cab of unit 3511 had been fused onto unit 3538 following collision damage.

The 1972 trains are formed of seven-car sets and have a total of 268 passenger seats. After withdrawal from the Northern Line, five four-car units (units 3201, 3208, 3211, 3212 and 3230)^{[ citation needed ]} were considered for use on the Waterloo and City line. The objective was to supply the Central line with extra 1992 stock. This never happened and the trains were sent to Mayer Perry or CF Booth of Rotherham to be scrapped.

Refurbishment

The fleet was refurbished between 1991 and 1995 by Tickford at Rosyth Dockyard.^[1] From 2016 to 2018, the fleet was again refurbished at Acton Works to enable the trains to remain in service until their forecast replacement date of 2035.^[2] The class received the Class 499/2 designation on British Rail's TOPS system to operate on the Bakerloo line north of Queens Park.^[4]

Future replacement

In the late 1990s, the Labour government initiated a public–private partnership (PPP) to reverse years of underinvestment in London Underground.^[5] Under the PPP contract, Metronet (the private consortium responsible for the Bakerloo line) would order new rolling stock for the Bakerloo line.^[6]^[7] This would take place following the delivery of 2009 Stock and S Stock trains, with an order for 24 new Bakerloo line trains. These would have entered service by 2019.^[6] However, Metronet collapsed in 2007 after cost overruns, and the PPP ended in 2010.^[8]

In the mid 2010s, TfL began a process of ordering new rolling stock to replace trains on the Piccadilly, Central, Bakerloo and Waterloo & City lines.^[9] A feasibility study showed that new-generation trains and resignalling could increase capacity on the Bakerloo line by 25%, with 27 trains per hour.^[9]

In June 2018, the Siemens Mobility Inspiro design was selected.^[10] These trains will have an open-gangway design, wider doorways, air conditioning and the ability to run automatically with a new signalling system.^[11] TfL could only afford to order Piccadilly line trains at a cost of £1.5bn.^[12] However, the contract with Siemens includes an option for 40 trains for the Bakerloo line in the future.^[13] This would take place after the delivery of the Piccadilly line trains in the late 2020s.^[11] Based on a November 2021 paper, due to a lack of funding, this might not happen until the late 2030s or early 2040s, when the trains would be 60 to 70 years old — probably double their design life.^[14] Since the withdrawal of the Class 483 on the Isle of Wight, the 1972-stock trains have become the oldest non-heritage trains running in the United Kingdom.

The Waterloo & City line, colloquially known as The Drain, is a shuttle line of the London Underground that runs between Waterloo and Bank with no intermediate stops. Its primary traffic consists of commuters from south-west London, Surrey and Hampshire arriving at Waterloo main line station and travelling forward to the City of London financial district. For this reason, the line has historically not operated on Sundays or public holidays, except in very limited circumstances. Following the COVID-19 pandemic, the line is currently only open on weekdays. It is one of only two lines on the Underground network to run completely underground, the other being the Victoria line.

The Central line is a London Underground line that runs through central London, from Epping, Essex, in the north-east to Ealing Broadway and West Ruislip in west London. Printed in red on the Tube map, the line serves 49 stations over 46 miles (74 km), making it the system's longest line. It is one of only two lines on the Underground network to cross the Greater London boundary, the other being the Metropolitan line. One of London's deep-level railways traversing narrow tunnels, Central line trains are smaller than those on British main lines.

The Bakerloo line is a London Underground line that runs from Harrow & Wealdstone in suburban north-west London to Elephant & Castle in south London, via the West End. Printed in brown on the Tube map, it serves 25 stations, 15 of which are underground, over 23.2 kilometres (14.4 mi). It runs partly on the surface and partly through deep-level tube tunnels.

The London Underground 1973 Stock is a type of rolling stock used on the Piccadilly line of the London Underground. It was introduced into service in 1975 with the extension of the line to Hatton Cross, followed by a further extension to Heathrow Central in 1977. A total of 86 six-car trains were built.

The 1959 Tube Stock was a type of London Underground tube train constructed in the late 1950s. They were intended for use on the Piccadilly line, but also saw use on several other tube lines. It was the first production tube stock to have unpainted aluminium alloy bodywork.

London Underground rolling stock includes the electric multiple-unit trains used on the London Underground. These come in two sizes, smaller deep-level tube trains and larger sub-surface trains of a similar size to those on British main lines, both running on standard gauge tracks. New trains are designed for the maximum number of standing passengers and for speed of access to the cars.

The London Underground 1938 Stock was a London Underground tube stock design. A total of 1,121 cars were built by Metro-Cammell and Birmingham RC&W. An additional 173 cars were added to the fleet by the end of 1953, comprising 91 new builds, 76 conversions from Pre-1938 Tube Stock or 1935 Tube Stock, and six unconverted cars of 1935 Tube Stock, and the stock was used on the London Underground until 1988. During their long lives they worked on the Bakerloo, Northern, Piccadilly, East London, Central, and Northern City lines. Ten sets were refurbished and ran on the Isle of Wight as Class 483, making them the oldest passenger rolling stock operating timetabled services on the National Rail network at the time of their withdrawal in January 2021.

The London Underground 1992 Stock is a type of rolling stock used on the Central and Waterloo & City lines of the London Underground. A total of 85 eight-car trains were built for the Central line and 5 four-car trains were built for the Waterloo & City line.

The Standard Stock title was applied to a variety of Tube stock built between 1923 and 1934, all of which shared the same basic characteristics, but with some detailed differences. This design is sometimes referred to as 1923 Tube Stock, 1923 Stock, or Pre 1938 Stock. Most of the Standard Stock was built to replace the first generation of "Gate Stock" Tube trains or to provide additional trains for extensions built in the 1920s and early 1930s. Standard Stock cars consisted of motor cars, with a driver's cab, behind which was a "switch compartment" occupying approximately one-third of the length of the car, plus trailer cars and "control trailers", with a driving cab but no motor. All were equipped with air operated sliding doors. The guard's door on the earlier trains was a manually operated, inward-opening hinged door.

The history of the London Underground began in the 19th century with the construction of the Metropolitan Railway, the world's first underground railway. The Metropolitan Railway, which opened in 1863 using gas-lit wooden carriages hauled by steam locomotives, worked with the District Railway to complete London's Circle line in 1884. Both railways expanded, the Metropolitan eventually extending as far as Verney Junction in Buckinghamshire, more than 50 miles (80 km) from Baker Street and the centre of London. The first deep-level tube line, the City and South London Railway, opened in 1890 with electric trains. This was followed by the Waterloo & City Railway in 1898, the Central London Railway in 1900, and the Great Northern and City Railway in 1904. The Underground Electric Railways Company of London (UERL) was established in 1902 to fund the electrification of the District Railway and to complete and operate three tube lines, the Baker Street and Waterloo Railway, the Charing Cross, Euston and Hampstead Railway and the Great Northern, Piccadilly and Brompton Railway, which opened during 1906–1907. By 1907, the District and Metropolitan Railways had electrified the underground sections of their lines.

Metronet Rail was an asset-management company responsible for the maintenance, renewal and upgrade of the infrastructure, including track, trains, signals, civils work and stations, on several London Underground lines. It was one of two infrastructure companies in a public-private partnership (PPP) with the Underground.

The London Underground 1983 Stock was a class of electric multiple unit built by Metro-Cammell for use on London Underground's Jubilee line.

The London Underground 1967 Stock was a type of deep-level train that operated on the Victoria line of the London Underground from the line's opening on 1 September 1968 until 30 June 2011. It was also used on the Central line between Woodford and Hainault between 21 February 1968 and 1984, as the same automatic train operation (ATO) system was used on both lines.

The London Underground 2009 Stock is a type of London Underground train built by Bombardier as part of its Movia family at its Derby Litchurch Lane Works, England. A total of 47 eight-car trains have been built for the Victoria line. They entered service between July 2009 and June 2011 and replaced the 1967 Tube Stock. It is the first new deep level tube stock on the Underground network since the 1996 Stock entered service on the Jubilee line in 1997.

<span class="mw-page-title-main">London Underground battery–electric locomotives</span>

London Underground battery-electric locomotives are battery locomotives used for hauling engineers' trains on the London Underground network where they can operate when the electric traction current is switched off. The first two locomotives were built in 1905 for the construction of the Great Northern, Piccadilly and Brompton Railway, and their success prompted the District Railway to buy two more in 1909, which were the only ones built to the loading gauge of the subsurface lines. Following this, a number of battery vehicles were built by converting redundant motor cars, with the batteries placed in the unused passenger compartment. One exception to this was made by the City and South London Railway, who used a trailer car to hold the batteries, and wired them to a separate locomotive.

The London Underground 1995 Stock is a type of rolling stock used on the Northern line of the London Underground. A total of 106 six-car trains were built, entering service between June 1998 and April 2001, replacing the 1959 Stock, 1962 Stock and 1972 Stock. They are externally similar to the 1996 Stock used on the Jubilee line.

The London Underground S7 and S8 Stock, commonly referred to as S Stock, is a type of passenger train running on the London Underground's subsurface lines since 2010. Manufactured by Bombardier Transportation's Derby Litchurch Lane Works, the S Stock was ordered to replace the A60, A62, C69, C77 and D78 stock on the Metropolitan, District, Hammersmith & City, and Circle lines, which all dated from the 1960s and 1970s.

Rolling stock used on the London Underground and its constituent companies has been classified using a number of schemes. This page explains the principal systems for the rolling stock of the Central London Railway (CLR), the Underground Electric Railways Company of London (UERL), the District Railway (DR) and the Metropolitan Railway (MR). For information about individual classes of locomotives and other rolling stock, see London Underground rolling stock.

The London Underground 2024 Stock, known as the New Tube for London (NTfL) during development, is a London Underground train being built by Siemens Mobility at its facilities in Goole, United Kingdom and Vienna, Austria. It is part of the Siemens Inspiro family of metro and rapid-transport trains.

Morden Depot is a British rolling stock depot on the London Underground Northern line, and is located to the south of Morden Underground station. It was opened in 1926, when the City and South London Railway (C&SLR) was extended from Clapham Common to Morden.
