The Dudding Hill Line (or Dudding Hill Loop) is a railway line in west and north-west London running from Acton to Cricklewood. It is roughly 4 miles (6.4 km) long, with a 30 miles per hour (48 km/h) speed limit, and semaphore signalling. The line has no scheduled passenger service, no stations, and is not electrified. It is lightly used by freight trains and, very occasionally, passenger charter trains.

The line was opened through open countryside on 1 October 1868 (goods) and 3 August 1875 (passengers) as the Midland and South Western Junction Railway,[2] as part of the Midland Railway's extension to London. It connected the Midland Main Line, and what would become its large Cricklewood goods yard, to the North and South Western Junction Railway, now part of the North London Line, at Acton Wells (an area now called North Acton).[3] It had stations at Dudding Hill and Harlesden (the latter also called Harrow Road and Stonebridge Park).[4]
From 1878 to 1880[3] it formed the basis of the Midland Railway's Super Outer Circle, which ran from St Pancras to Earl's Court via Cricklewood, Acton and the District line.[5] Various other, shorter routes were then used, but passenger demand was low, and it was closed to regular passenger traffic in 1902.[3]
Although railway usage is almost always "Dudding Hill Railway", the geographical area is usually called "Dudden Hill", and there is a London Borough of Brent electoral ward of that name. Dudden Hill is named after a Saxon settler called Dodda. The earliest known record, as Dodynghill, dates from 1544. "Dudding Hill" has been regarded historically as the more genteel spelling of the name.[7]
At various times,[when?] summer special trains were run on the Dudding Hill Line, to carry holidaymakers from the Midlands to south coast holiday resorts.
The main traffic is aggregates (including to a cement depot at Neasden) and compacted household waste from depots at Brent Cross and Dagenham to the land-fill site at Calvert in Buckinghamshire.
The line is still authorised for passenger services. Very occasionally, it is used for chartered passenger trains, including Pullman heritage coaches.
In 2009, the track received considerable maintenance in parts, including complete track and ballast removal and replacement.
Chiltern Railways use the line to take faulty rolling stock to Willesden Depot via Neasden Junction, accessible from the "up" line at Wembley Stadium.[citation needed]
Development proposals
Crossing the Dudding Hill Line in late Victorian times, near the eastern end of Dudding Hill station, and at the western end of Gladstone Park
In July 2008, a high-speed rail network was proposed by the 2M Group, a campaigning group representing people affected by Heathrow Airport expansion, as an alternative to increased air traffic. A rail route running from Heathrow to Cambridge would connect with the Midland Main Line at a "Cricklewood Interchange" station, using new track north from Heathrow to Ruislip, then the Great Central Line (nowadays the Chiltern main line) to Neasden, then a short northernmost section of the Dudding Hill Line from Neasden to Brent Cross.[15]
After several independent efforts, in early 2009 the British Government began an official detailed study of possible high-speed rail routes.
London Overground proposal
In June 2013, the Mayor of London and the London Boroughs of Brent, Ealing and Hammersmith & Fulham released 'vision' consultation documents[16] about the Old Oak Common area of west London. This involves a major development area for London, based around a new Old Oak Common station for High Speed 2 and Great Western Main Line, including Crossrail.
In October 2016, a report by Jonathan Manns and Dr Nicholas Falk, on behalf of the UK Government's All Party Parliamentary Group for London's Planning and Built Environment, proposed new orbital rail links in West London modelled on Swift Rail or Rapid Transit, connecting existing communities and those which could accommodate additional growth. It encouraged West London Business (West London Alliance) to reconsider work it had commissioned in 2001 which flagged the scope to connect Old Oak Common and Brent Cross along the Dudding Hill line. This connection was supported in addition to smaller connections using underused or unused existing connections.[17]
It was agreed at the following meeting of the West London Economic Prosperity Board, in December 2016, to undertake further analysis on the feasibility of establishing an orbital passenger rail connecting regeneration schemes.[18] The findings were presented in June 2017, on the basis of which the Board voted to progress engagement with the Mayor of London around a West London Orbital.[19] The Mayor put forward a proposal to work with the West London Alliance and others to deliver a West London Orbital in March 2018, following publication by the West London Alliance of a proposal.[20]
On the Midland Main Line new platforms would be built at Hendon and at Cricklewood and West Hampstead, while the Hendon service could also call at Brent Cross West. The West Hampstead branch would be complete by 2026 and the Hendon branch by 2029 with 4 trains per hour on each branch end.[21] The project's benefit-to-cost ratio is estimated to be in excess of 50:1.[22][23]
