Automation of the London Underground

Last updated

Automation of London Underground rolling stock has been partially implemented since the introduction of automatic train operation on the Hainault to Woodford section of the Central line in 1964. It is currently in use on six lines.

Historical projects

Partially automated trains using automatic train operation (ATO) have been used on passenger services on the Victoria line since 1968. [1] The side doors to the driver's cab were sealed, so that access was normally through the passenger saloon. Since the trains were to be operated by one person, the door controls were moved from the rear end of the motor car into the cab. The train control equipment was fitted beneath the centre seats, and consisted of a "black box", which interpreted signals received from the running rails. These were picked up by sensing coils mounted on the leading bogie. One rail supplied safety information, which was received continuously. Any failure to obtain this data resulted in a trip-valve operating, which stopped the train. The second rail supplied signal commands, which included speed signals and instructions to start and stop the train. This information was only provided when it was needed. The driver was renamed a train operator, and was responsible for opening and closing the doors at stations, and initiating a start from the stations, by pressing two buttons simultaneously. All other operation, including stopping at signals and restarting when safe to proceed was automatic. The automatic control equipment was temporarily mounted in the passenger saloon, between the cab and the first set of doors, to enable engineers to monitor and adjust it as experience was gained.[ citation needed ]

Current status

Partially-automated trains are used on eight lines: (Victoria, Jubilee, Central, Northern, District, Circle, Hammersmith and City, Metropolitan). [2] These trains still require operators to open and close the doors, and to assist in the event of an emergency. This method of working will also be used on Thameslink and is used on Crossrail. [3]

London's second rapid-transit system, the Docklands Light Railway (DLR), has operated with driverless trains since its opening in 1987. [4]

Boris Johnson promised in 2012 that there would be driverless Tube trains within 10 years. During his campaign to be re-elected as London Mayor, he said "TfL (Transport for London) will rapidly establish a timetable for introducing the first driverless trains to become operational on the London Underground network within a decade". That was cheered by Brian Paddick (Lib Dems), but Ken Livingstone (Labour) said it was a 'vanity project', and Jenny Jones (Greens) said that she had concerns over the safety of driverless trains. [5]

The then deputy cabinet member for sports, leisure and customer services at Westminster City Council, Richard Holloway, launched a petition in August 2015 demanding the introduction of driverless trains. [6]

Benefits and drawbacks

Possible benefits

Criticism

New Tube for London programme

The New Tube for London programme will include driverless tube trains. However these will initially have a driver on board until old stock has been fully replaced (i.e. Grade of Automation level 2, currently used on ATO-equipped lines). Even then, they will still have "train captains" on board in case of emergency (i.e. Grade of Automation level 3, as used by the DLR), due to driver union opposition of fully automated, unattended trains (i.e. Grade of Automation level 4, as used by some lines of the Paris Métro).

<span class="mw-page-title-main">Elevated railway</span> Rapid transit railway with the tracks above street level

An elevated railway or elevated train is a railway with the tracks above street level on a viaduct or other elevated structure. The railway may be broad-gauge, standard-gauge or narrow-gauge railway, light rail, monorail, or a suspension railway. Elevated railways are normally found in urban areas where there would otherwise be multiple level crossings. Usually, the tracks of elevated railways that run on steel viaducts can be seen from street level.

Automatic train operation (ATO) is a method of operating trains automatically where the driver is not required or required for supervision at most. Alternatively, ATO can be defined as a subsystem within the automatic train control, which performs any or all of functions like programmed stopping, speed adjusting, door operation, and similar otherwise assigned to the train operator.

<span class="mw-page-title-main">Rapid transit</span> High-capacity public transport commonly found in urban areas

Rapid transit or mass rapid transit (MRT), also known as heavy rail or metro, is a type of high-capacity public transport that is generally built in urban areas. A rapid transit system that primarily or traditionally runs below the surface may be called a subway, tube, or underground. Unlike buses or trams, rapid transit systems are railways, usually electric, that operate on an exclusive right-of-way, which cannot be accessed by pedestrians or other vehicles. They are often grade-separated in tunnels or on elevated railways.

Communications-based train control (CBTC) is a railway signaling system that uses telecommunications between the train and track equipment for traffic management and infrastructure control. CBTC allows a train's position to be known more accurately than with traditional signaling systems. This makes railway traffic management safer and more efficient. Metros are able to reduce headways while maintaining or even improving safety.

<span class="mw-page-title-main">History of train automation</span>

The history of automatic train operation includes key dates for system introductions of different Grade of Automation. The lower grades, such as the German Punktförmige Zugbeeinflussung introduced in 1934 have been available earlier. Higher grades, such as the driverless operation have been introduced almost only in case automated guideway transit.
