The route runs for approximately 11 miles from West Hampstead and Hendon at the northern end to Hounslow at the Western end via Brent Cross West, Neasden, Harlesden, Old Oak Common, Acton and Brentford. The route would improve rail connectivity across West and North London, and establish a number of new connections to existing radial rail infrastructure including Thameslink, the Jubilee Line, Bakerloo Line, High Speed 2, Crossrail and the Piccadilly Line. It is anticipated the line will be operational by the mid-2020s, reflecting the fact that it makes use of existing under-used rail infrastructure rather than requiring significant lengths of new track or tunnels to be built. An unrelated scheme of the same name was previously proposed in June 2008 by the West London Business group. That proposal involved the construction of a new underground line across West and South West London and did not progress beyond concept stage. Detail of the schemeThe West London Orbital line consists of a number of distinct sections: The Dudding Hill Line, the North London Line and the Hounslow Loop. The Dudding Hill line itself has had no scheduled passenger service for over a century. It has no stations, no electrification and a 30 miles per hour (48 km/h) speed limit with semaphore signalling, and is lightly used by freight and very occasional passenger charter trains. It is roughly 4 miles (6.4 km) long. Near the site of Old Oak Common the West London Orbital would connect to the existing North London Line, and then further south at Acton, use the link down to the Hounslow Loop to reach Brentford and Hounslow. Taken together, this set of routes would be known as the “West London Orbital” railway. In March 2017 the West London Alliance group of local authorities commissioned a study to assess the feasibility of the line so that a decision could be taken as to whether it merited pursuing further. This study found that:
In June 2017 Transport for London published the [https://www.london.gov.uk/what-we-do/transport/our-vision-transport/draft-mayors-transport-strategy-2017 draft Mayor’s Transport Strategy], which stated that London government would work with the relevant boroughs to explore the feasibility of the proposed service, that would become the West London Orbital. In March 2018 the [https://www.london.gov.uk/moderngov/documents/b16916/Draft%20Transport%20Strategy%20Thursday%2008-Mar-2018%2010.00%20London%20Assembly%20Plenary.pdf?T=9 Mayor's Transport Strategy] was published, which includes a proposal for this 'orbital' connection to Old Oak between Hounslow and Brent Cross. Current positionThe London [https://www.london.gov.uk/moderngov/documents/s69147/PUB18_001_MTS_NewJobsAndHomes_230218-4.pdf Mayor's Transport Strategy] (MTS), published on 28 February 2018 and ratified by the London Assembly on 8 March 2018, includes plans for a West London Orbital railway line under Proposal 88. The mayor’s proposal for the service highlights that utilising new and existing orbital connections in west London could also improve public transport connections in the city centre. It reads: “Most Londoners want to move around London – rather than in and out of the centre – every day, and the London Overground supports this type of travel. London Overground train service improvements are therefore needed to support new jobs and housing throughout inner London and parts of outer London.” The West London Alliance group of local authorities have agreed that the West London Orbital Scheme is to be a shared strategic infrastructure priority across borough boundaries, and that it will be incorporated in to all Local Plans. Discussions are currently underway[1] between West London councils and London government on the future of the scheme. A number of independent analysis of the scheme have been undertaken, including by Modern Railways[2] magazine and the independent blogging community[3][4] Earlier proposalsA number of routes have previously been examined for new orbital tube lines and improved connectivity across West and North London. It was considered that the most likely route of the previous proposal would be a north-south route running from Brent Cross to Surbiton, via Wembley Park, Ealing Broadway, Richmond and Kingston fully underground, connecting several London Underground and National Rail lines, including the forthcoming Crossrail 1 at Ealing Broadway. The proposal envisaged an underground driverless light rail train system similar to the Docklands Light Railway, and updated "to the most modern standards". The transit time from Brent Cross to Surbiton was quoted as 28 minutes, with a maximum train speed of 80 km/h. The promoters cited a number of reasons why they believed an underground scheme would be cost-effective at £1.75bn: with lower tunnelling costs as the tunnel diameter would be smaller than for a heavy rail scheme; there are no other rail tunnels to avoid (as in central London); and the subsoil strata are suitable for modern tunnel boring machines (TBMs).[4] Alternative orbital schemesA number of other notable orbital rail schemes for London have been previously proposed:
