The Acton–Northolt line (ANL), historically known as the New North Main Line (NNML), is a railway line in west London, England. Built between 1903 and 1906, it runs from the Great Western Main Line at Old Oak Common TMD to the Chiltern Main Line at South Ruislip, alongside the West Ruislip branch of the London Underground Central line, for a distance of around 11 miles (18 km). At present, it is little used.

It opened in 1903 as part of a joint project by the Great Central Railway (GCR) and the Great Western Railway (GWR) to improve their termini's access from London to the Midlands and North of England, especially relative to the London and North Western Railway (LNWR). It begins at Old Oak Junction on the Great Western Main Line from Paddington and runs via Greenford to join what is now the Chiltern Main Line at Northolt Junction, southeast of South Ruislip.
The line joined the Great Western and Great Central Joint Railway between West Ruislip and Denham station in 1906. Its original name was "Denham – Junction for Uxbridge" as it was planned to be a stop on the shuttle service between Gerrards Cross and Uxbridge High Street. The latter was closed in 1964 and later demolished.
In the past it carried many trains to the northwest, and it was heavily used in the 1960s when electrification work restricted capacity on the West Coast Main Line (WCML); but when that project was completed, express services from London to Birmingham on the GWR/GCR route were discontinued as part of the Beeching Axe. All local trains on the route were diverted to Marylebone via Sudbury in 1963, and Greenford station on the New North Main Line was closed.
In the early 1990s the New North route was reduced to a single-track layout between Old Oak Common and Park Royal and between Greenford and South Ruislip. No improvement work has been carried out on the line since then.
Plans at this date to do away with Greenford East signal box and its semaphore signals, with upgraded signalling controlled by Slough and Marylebone signalling centres, were postponed indefinitely as decline of rail traffic controlled by Greenford East did not justify the cost.
As described, the Central line has largely replaced its business.
Chiltern Railways operates a token Paddington service on weekdays; in some timetable revisions it has been one up or one down train, or one of each way between West Ruislip and Paddington calling at South Ruislip. The line is still used for goods trains carrying refuse from London and for empty coaching stock movements, and it is a diversionary route when the normal lines to Marylebone or Paddington are closed.
For operational reasons such as balancing wheel wear, trains including those of Heathrow Express which were affected by tight track at Heathrow Junction have been turned using the London end of the NNML, its triangular junction with the Greenford Branch Line and the GWML through Ealing. At weekends in 2008 when major engineering works were taking place on the West Coast Main Line, it was also used by Virgin Trains' Euston–Birmingham International Blockade Buster service, which ran from London Euston via Willesden, Acton Main Line, Ealing Broadway, Greenford, High Wycombe, Banbury and Coventry using pairs of 5-car Voyager sets. At other times it has been used by Chiltern Main Line services when the route to Marylebone is blocked; or by Great Western Main Line services (via Banbury and Didcot) if the line through Reading is blocked.
The route is also used for testing out new trains and for the training of new drivers.
Ruislip Waste Transfer
An HS2 station is proposed for the combined part of the route with the GWR at Old Oak Common, provisionally known as 'Crossrail interchange', for connections to and from Crossrail. Additional tunnelling under the New North Main Line will keep the line free for other potential passenger services, as in the April 2013 published decision by HS2 Ltd and the Department for Transport to recommend further bore tunnelling under the 5.6 miles (9.0 km) of the 'Northolt Corridor' within the London Borough of Ealing.
The tunnel will minimize traffic and noise blight which a surface route would otherwise have caused. The further bore tunnelling will link up the tunnels already planned beneath South Ruislip and Ruislip Gardens and Old Oak Common to North Acton. HS2 Ltd found in a study it had undertaken that bore tunnelling this stretch of the HS2 route would take 15 months less than constructing a surface HS2 route through this area and be at least cost-neutral. Cost neutrality flows from avoiding 20 bridge replacements, particularly 3 1⁄2 years to replace road over rail bridges at the Hanger Lane Gyratory System, amenity disruption, the construction of intermediate tunnel portals and the likelihood of substantial compensation payments. The tunnelling will mean the New North Main Line is severed twice. It has not been decided whether the line will be restored once construction is complete.
In a summary report by Network Rail which was released in 2017 proposed that by 2043 that there should be a new terminal at Old Oak Common. This would mean an upgrade of the line to allow regular trains to once again run to the Great Western Main Line replacing the current parliamentary service which runs from High Wycombe to Paddington. Up to 4 trains per hour could run to Old Oak Common by 2043. The proposed upgrade would see redoubling of the line to a two-track railway with the possibility of line speed improvements into the one or more platforms that could be provided at ‘Old Oak Common’ for the Chiltern Main Line. The number of platforms would depend on the number of services.
The line's former stations and sidings
Ruislip Gardens tube station
The tracks through the station were laid by the Great Western and Great Central Joint Railway with services starting on 2 April 1906, although there was no station at Ruislip Gardens at that time. The station opened on 9 July 1934.
As part of the 1935–40 New Works Programme, Central line services were projected westwards from a new junction, west of North Acton on the line to Ealing Broadway. The original intention was to extend the service as far as Denham, but work was delayed by World War II and the terminus of the extension was cut back to West Ruislip, with services starting on 21 November 1948.
Mainline services calling at Ruislip Gardens ceased in 1958 and the mainline station closed, the Central line station remaining open. Until recently the entrance to a passenger stairwell was visible on the London-bound side of the Network Rail tracks.
Northolt goods yard and carriage sidings
These served several local businesses and were also used to store spare British Rail and London Underground stock on occasion. They were abandoned in the early 1990s.
Northolt Halt and station
Northolt Halt, located alongside the current Northolt tube station, was opened by the GWR in 1907. It was later renamed "Northolt (for West End) Halt", before gaining station status under its original shorter name. It was closed in 1948 following the extension of the Central line to West Ruislip, the current tube station opening on 21 November 1948.
British Bath Company siding
This siding served the British Bath Company factory beside the Paddington Branch of the Grand Union Canal. It was lifted when the factory closed in the late 1970s, and the area is now occupied by Fairway Industrial Estate.
Kelvin Construction siding
This siding served the Kelvin Construction factory, next to that of the British Bath Company. The area is now occupied by Kelvin Industrial Estate.
Aladdin Industries siding
This siding served the Aladdin lamp factory, a short distance south of the British Bath Company and Kelvin factories. It was lifted when the factory closed in the early 1980s (although the main factory building is still extant), and the area is now occupied by a business park.
A Rugby Cement Terminal was immediately to the west of the former Greenford station up platform. This closed in about 1990.
The present station, adjacent to the original, was built as part of the Central line extension of the 1935-40 New Works Programme of the London Passenger Transport Board. It opened on 30 June 1947 after delay due to World War II. Service at the original station was gradually reduced and it was closed in 1963.
Greenford freight sidings
These served several local businesses, but were closed in the 1990s.
Perivale GPO sidings
These served the local Royal Mail distribution centre and sorting office, but were closed in the early 2000s.
Perivale Halt railway station
The Great Western Railway opened "Perivale Halt" on 2 May 1904. It closed on 15 June 1947, after the extension of the Central line to Ruislip. It had long wooden platforms and pagoda shelters, on an embankment reached by sloping paths west of Horsenden Lane South. The steam "push-and-pull" passenger service ran to Paddington; the line (the last main line to be built before HS1) was shared with freight and with express trains to Birmingham (2 hours non-stop). Until the late 1920s, Perivale was entirely rural, despite its proximity to Ealing.
A Lens of Sutton photograph of the station is on page 77 of The forgotten Stations of Greater London by J.E. Connor and B.L. Halford (Connor and Butler) (ISBN 0947699 17 1). There was a similar halt at South Greenford before it was modernised by Network SouthEast.
The current London Underground station was opened on 30 June 1947.
Sanderson & Sons sidings
Hanger Lane facilities
Twyford Abbey Halt and Brentham station
Twyford Abbey Halt, located just to the east of the current Hanger Lane tube station, was opened by the GWR on 1 May 1904. It was closed on 1 May 1911 and replaced by Brentham station, located to the west. This station, later renamed "Brentham (for North Ealing)", was closed between 1915 and 1920 due to World War I economies, and closed altogether in 1947 when the Central line was extended to West Ruislip. The current tube station, which opened on 30 June 1947, was called Hanger Lane as it was near that road.
Hanger Lane sidings
These few sidings were used by both London Underground and local businesses. They have now been mostly removed and the remaining one was heavily overgrown as of 2008.
Park Royal facilities
Park Royal West Halt
This halt was open between 1932 and 1948. It was located just to the east of the bridge carrying the London Underground Piccadilly line.
Park Royal Guinness brewery and sidings
In 2004, the multinational company Diageo agreed to build extra Central line platforms at Park Royal tube station, as part of its First Central business park, built on the site of the former Guinness brewery. As of 2010, this had not yet happened.
Park Royal station
Park Royal station opened with the line in 1903, and closed in 1937. It should not be confused with the current station of the same name on the Piccadilly line, which opened in 1931.
British Can Company sidings
These sidings served the Acton factory of the British Can Company (later taken over by Metal Box & Printing Industries), as well as the adjacent Walters' Palm Toffee factory. They were lifted in the mid-1960s, although the bridge that carried them over the Central line is still extant.
The Fiat (England) siding

The Marcon Topmix stone terminal sidings
North Acton tube station
|“||On 18 August 1911, the Central London Railway abandoned its policy of no through running with any other railway, and secured powers to build a short extension from Wood Lane to connect with the intended Ealing & Shepherds Bush line of the Great Western Railway, over which it proposed to exercise running powers.||”|
North of the Central line tracks were two freight lines, removed in the 1960s, running alongside the Central line as far as White City. To the north of those at a slightly higher level were the two tracks of the NNML. The footbridge to the NNML platforms is on the extreme left of this 1933 photograph.
The NNML platforms closed when the Central line was extended on new track from North Acton to Greenford station in 1947. Between South Ruislip station and Old Oak Junction, the GWR line was progressively run down, and in many places it is now single-track, including the stretch running past the tube station. By May 2008 only freight trains and a token once-daily passenger service provided by Chiltern Railways used this stretch of line.
Old Oak Lane Halt railway station
Old Oak Lane Halt railway station was opened by the Great Western Railway in 1906 within the complex of lines at the south east end of the New North Main Line, a location with low potential for passenger traffic. It closed in 1947 without a replacement when the Central line of London Underground was extended from North Acton to West Ruislip alongside the NNML under the 1935-1940 New Works Programme delayed by World War II.
