The Oxted line is a railway in southern England and part of the Southern franchise. The railway splits into two branches towards the south and has direct trains throughout to London termini.

It was opened jointly by the London, Brighton and South Coast Railway and the South Eastern Railway in the late 19th century.

The line branches from the London to Brighton Main Line (which has two diverging northern branches) at South Croydon in Greater London. The line then passes under the North Downs in two tunnels, and then splits into two branches at Hurst Green, adjoining Oxted in Surrey. One of these branches ends at East Grinstead, the other at Uckfield, both market towns in Sussex.

The line between East Croydon and Hurst Green is double-track throughout, as is all of the East Grinstead branch, and all this route is electrified. The Uckfield branch has two tracks as far as Hever; the rest of the line is mostly single-track, but with two short double-track sections (a passing loop at Ashurst, and a short distance between Crowborough and just north of Buxted).

History

Conception

A line was proposed in 1864 from Croydon to Tunbridge Wells via Oxted by a group of former LB&SCR directors. Their proposal for the Surrey and Sussex Junction Railway (S&SJR) was to have the scheme underwritten and then operated by the LB&SCR.

However, the South Eastern Railway (SER) saw the S&SJR, and particularly the involvement of the LB&SCR chairman Leo Schuster, as a significant incursion into its territory. In addition to creating a rival to its own line to Tunbridge Wells, the SER saw the LB&SCR's direct involvement as contravening an 1849 agreement between the two companies. In retaliation, the SER put forward proposals for a 'London, Lewes and Brighton' railway together with the London Chatham and Dover Railway. As a result of these difficulties and the financial crisis of 1866–7, the LB&SCR signed a new agreement with the SER in which it withdrew support for the S&SJR, and the SER abandoned its scheme. Work on the S&SJR immediately ceased, but the holding company remained in existence until 1869, when it was merged with the LB&SCR and then closed.

On 10 March 1884, the LB&SCR and the SER formed a joint venture company, the Croydon, Oxted & East Grinstead Railway. Surveyed and engineered by the LB&SCR's Chief Engineer Frederick Banister, the proposed route in part used trackbed constructed for but never used by the S&SJR. The line was jointly owned and operated until Hurst Green, when it split into three:

• to Crowhurst South junction, allowing connection to the SER's Redhill–Tonbridge line
• to East Grinstead, owned by the LB&SCR but jointly operated with the SER
• to Eridge, owned by the LB&SCR with junctions with the Wealden Line, the Three Bridges to Tunbridge Wells Central Line, and the Cuckoo Line

Part-electrification

The Southern Railway electrified the Woodside and South Croydon Joint Railway in 1935 but the line closed in 1983. Some of the redundant materials were used to electrify the short section between South Croydon and Selsdon railway station in 1984 and a few electric trains then operated from London to Sanderstead via East Croydon. The section beyond Sanderstead to East Grinstead was electrified in 1987 at 750 V DC third rail. However, the Uckfield branch is not electrified, and is worked by Class 171 diesel multiple units, which replaced Class 205 and Class 207 DEMUs.

Route

South Croydon to Hurst Green

The line branches off from the Brighton Main Line at South Croydon. It runs roughly parallel to the Caterham line until Upper Warlingham as it passes across Riddlesdown Viaduct and through Riddlesdown Tunnel, and the stations of Sanderstead and Riddlesdown. Leaving Greater London the line then passes through Upper Warlingham and Woldingham before traversing the 2226 yard Oxted Tunnel under the North Downs. After passing beneath the M25 motorway, the line calls at Oxted.

Previously, most Uckfield branch services would terminate here, but since the mid 2000s, they now run through to London Bridge. On Sundays however, the old practice persists, with services to and from Uckfield departing from the rarely used bay platform.

Immediately south of Oxted station, the line passes over the A25 and the town of Oxted by means of the Oxted Viaduct. After another shorter tunnel the line reaches Hurst Green. Hurst Green junction lies immediately south of the station, with trains to Uckfield veering left, and trains to East Grinstead continuing straight on.

Hurst Green to East Grinstead

The East Grinstead branch continues south through Surrey and into West Sussex. The first stop from Hurst Green is Lingfield, best known for being adjacent to Lingfield Park Racecourse, and trains are busy on race days. Further south, the line crosses a series of viaducts before arriving into the village Dormansland, served by Dormans station. The line then enters a cutting, passing under a series of roads including the A22 as it passes through the suburbs of East Grinstead. It then terminates at East Grinstead station, though the line used to go further, towards Haywards Heath and Lewes.

The line south of East Grinstead is now preserved as the Bluebell Railway and interchange is available at the station.

Hurst Green to Uckfield

The Uckfield branch of the Oxted Line is unelectrified. It passes under the Redhill–Tonbridge line just north of Edenbridge Town station, and then arrives at Hever. South of Hever, the line's single track section commences. This runs through Mark Beech Tunnel and Cowden station before entering a Passing loop at Ashurst. The off peak timetable on the line means that trains to and from Uckfield usually pass here. The line skirts the Kent and East Sussex border for a while before finally entering the latter county and passing a series of junctions where long closed lines to East Grinstead High Level, Three Bridges and Tunbridge Wells diverge. The line to Tunbridge Wells West is now the Spa Valley Heritage Railway and runs parallel to mainline trains on the old down line. Interchange between the two lines is available at Eridge, an old junction station.

South of Eridge, the line passes the former Redgate Mill Junction, where the Cuckoo Line to Heathfield and Eastbourne used to diverge from before arriving at the lines second passing loop at Crowborough. South of Crowborough the line becomes single for the final time calling at Buxted and finally Uckfield. The line used to go further, with Uckfield's original station on the other side of the now closed Level crossing. Trains used to continue towards Lewes and Brighton via the Wealden Line.

Services

Off-Peak service map on the Oxted Line

Typical off-peak services on the Oxted Line are:

• 2 tph from London Victoria to East Grinstead calling at Clapham Junction, East Croydon, Sanderstead, Riddlesdown, Upper Warlingham, Woldingham, Oxted, Hurst Green, Lingfield and Dormans
• 1 tph from London Bridge to Uckfield calling at East Croydon, Oxted, Hurst Green, Edenbridge Town, Hever, Cowden, Ashurst, Eridge, Crowborough and Buxted. In peak hours, this service increases to 2 tph.

In peak hours, 2 tph between Bedford/Luton and East Grinstead. This service calls at all stations between South Croydon and East Grinstead, except in the mornings southbound, and evenings northbound, it skips stations between Sanderstead and Oxted exclusive.

On Sundays, the London Bridge to Uckfield service runs only between Oxted and Uckfield.

Oyster and contactless payment cards are valid on the Oxted route as far as Upper Warlingham.

Connections with heritage railways

The two branches of the line connect with different heritage railways directly:

• the Spa Valley Railway runs from Tunbridge Wells West to Eridge, where it has restored the disused down island platform and commenced services on 25 March 2011.
• the Bluebell Railway runs from Sheffield Park to East Grinstead, where it has built a new single-platform station which interchanges with the National Rail station. Through running to Network Rail started in March 2010, when GB Railfreight was contracted to run occasional trains carrying 1,000 tons of excavated material from the Bluebell's northern extension to a disposal site at Calvert, Buckinghamshire. Passenger services started on 23 March 2013.

Former connections and sub-branches

One branch formerly had three sub-branches:

• from East Grinstead to:
  • Three Bridges
  • Lewes; the northernmost section of this branch is preserved as the Bluebell Railway, operated by steam and classic trains.
  • Tunbridge Wells.

(All three of these terminus towns are served by other lines.)

• Ashurst on the Uckfield branch was a junction for Tunbridge Wells (Kent) part of which is used by the 'Spa Valley Railway'.
• Eridge on the Uckfield branch is a junction for Tunbridge Wells (Kent) used by the 'Spa Valley Railway' It was until 1965 a junction for Cuckoo Line to Eastbourne.

A short stretch of the "main line", between Uckfield and Lewes is preserved at Isfield as the Lavender Line.

Between Hurst Green and Lingfield (in Surrey) there was a connection with the Redhill to Tonbridge line until 1965. Until 1983 there was a junction at Selsdon (in Greater London) with the Woodside and South Croydon Joint line to Elmers End.

Proposed developments

A £140,000, six-month study was commissioned by the East Sussex County Council and Network Rail looking into the possibility of rebuilding the line between Uckfield and Lewes after a campaign by the Wealden Line Campaign Group. In July 2008 the Central Rail Corridor Board (a joint group of local councils and stakeholders) study, commissioned by Network Rail, reported that there was not a forecast viable economic case for reopening, citing a £141 million cost and a low anticipated benefit to cost ratio (BCR) of 0.64 to 0.79; in comparison a BCR of 1.5 was the minimum needed to obtain finance for the scheme.

Brighton Main Line 2

The Wealden Line Campaign Group has, in addition to campaigning for the reopening of a line between Uckfield and Lewes, proposed an extension north from Sanderstead to Elmers End. There would also be new platforms at Brighton, and 5 miles (8.0 km) of the East Coastway line would be upgraded. The line would branch off the East Coastway beyond Falmer. A new Ashcombe tunnel would be bored after crossing the A27 before crossing the Keymer Junction (in Burgess Hill) to Lewes line. The line would take back the preserved Lavender Line at Isfield. No stations would be reopened between Lewes and Uckfield, and all level crossings would be closed. A new station at Uckfield south of the current one would allow 12-carriage trains. The line to Eridge would be double-tracked and electrified, with a maximum speed limit of 90 miles per hour (140 km/h). New passing loops at Eridge would allow fast trains to overtake slower stopping services. The proposal also includes bringing the Eridge to Tunbridge Wells line back into operation, with through services to Brighton from Royal Tunbridge Wells. The line between Brighton and Oxted/Tunbridge Wells would be electrified with overhead wiring (25 kV AC).

Instead of carrying on to the Brighton Main Line, the line would branch off at Sanderstead and reopen the former line, but Croydon Tramlink has taken over the section between Coombe Road and Elmers End. The line would join the Hayes Line at Elmers End possibly alongside the proposed Bakerloo line extension to Hayes and then run to London Bridge, London Charing Cross and possibly on to the Thameslink network. There is also a suggestion for some trains to run on the East London line and branch off after Whitechapel to London Liverpool Street or onto a new line to Stansted Airport via Canary Wharf and Stratford. The whole project could see as little as one building demolished.

The project would have trains diverted away from bottlenecks at East Croydon and Windmill Bridge junction, and provided more capacity between London and Brighton.
