The branch leaves the East London Line south of . This branch allows passengers to interchange onto the South Eastern Main Line, but the tracks are not connected.

A train servicing and stabling facility has been built on the Silwood Triangle, a disused plot of land just north of New Cross Gate station.

At New Cross Gate, Platform 1 and adjacent track (southbound) have been extensively refurbished, with the line continuing under New Cross Road, before merging with the existing southbound slow line. North of the station and the junction with the branch to , between Canal Road and Rotherhithe New Road, extensive works were carried out to allow the Western Extension (see below) to merge efficiently with the existing alignment; this work was authorised and funded in 2008 prior to the final approval of the Western Extension.

, which ran all train services to these stations. They have now transferred to TfL control, but Southern continues to run its own regular services into London Bridge on this section of route as well (albeit less frequently than before), so that northbound passengers at such stations as Brockley or Forest Hill now have a choice of destination, either London Bridge as before, or via the new line towards Dalston.

The existing (also known as the 'Classic') section of line has been completely overhauled, with the replacement of all track and signalling upgraded to Network Rail standards.

The extension will require the construction of 1.5 mi (2.4 km) of new track, to be laid on a disused alignment which until 1911 was used by trains from Rotherhithe to Peckham via the now-defunct Old Kent Road railway station

. The points and the major part of the civil works to effect the junction from this line to the refurbished East London Line (ELL) south of Surrey Quays, including a southbound flyunder, are already complete, as part of the Phase 1 works. South from the ELL junction the line will pass through existing arches under several lines approaching London Bridge. From there to Surrey Canal Road the embankment will be built up to a new bridge over the road, where there are existing bridge abutments, which currently support a footbridge which will be dismantled. On the other side of the bridge the line will pass through Bridgehouse Meadows to a crossing over Hornsay Street, near where a junction will be effected with the inner South London line.

During January and February 2011 the required alignment had been largely cleared of debris and excess vegetation, but no construction had begun. By early April, contractors were on the Bridgehouse Meadows site, and the footpath across the site from Surrey Canal Road southwards was closed to the public. Footpaths following the route will continue to be closed during construction, but will be restored on completion, as will that part of Bridgehouse Meadows not occupied by the new railway.

A new station might be built at , but funding for this has not yet been agreed and in September 2010 funding was refused by the Department for Transport

.

There will be additional platform capacity at Clapham Junction for the new services, but the exact arrangements for this have yet to be finalised. Trains will run every 15 minutes, and contribute to an eventual 16 trains per hour on the core ELL section between Surrey Quays and Dalston Junction.

Train services and rolling stock

The core section of the line, between Dalston and Surrey Quays, is served by 16 trains per hour. New Cross Gate to Sydenham has 8 trains per hour. The remainder of the line is served by four trains per hour. A total of 30 stations will be served by the new line.

A solution to the funding issue was found in 1999 when London Transport announced that it was seeking private funds to realise the extension plans. Control of the project was given to the Strategic Rail Authority

, the privatised company responsible for maintaining the mainline network. This would have seen the line integrated with the London suburban commuter network. However, it was soon decided that this was impractical and the Railtrack proposal was abandoned.

Network Rail's South London Route Utilisation Strategy has also very strongly emphasised the need for the phase 2 link to the Inner South London Line, particularly in respect of the even more restricted capacity during the reconstruction of London Bridge.

Alternative routes

A number of different routeing proposals were put forward before the route of the northern, southern and western extensions was finalised.

On the northern extension, early proposals mentioned the possibility of further extending the line from to to the north, and to the west, through , and , using the North London Line tracks. This would have enabled the line to be part of an orbital railway or "Orbirail

. The proposals were not adopted for the present project. Finsbury Park was ruled out because of operational complexity, though the project team has left open the possibility that an extension to Willesden Junction could be considered as a separate project in the future. The current track plans show the East London and North London lines separated, without the possibility of through running.

The southerly route across south London's existing network of suburban railways underwent many changes before a final route was decided. Initial proposals around 1992 envisaged the western extension running from Peckham Rye to East Dulwich. The 1999 proposals listed four options, all starting south of Surrey Quays:
  • through to West Croydon station

    , with a spur from Sydenham to (a route eventually selected and implemented for part of Phase 1);
  • through and to (rejected);
  • through to (the route eventually selected for Phase 2);
  • through Forest Hill and to West Croydon (a route eventually selected and implemented for part of Phase 1).


In the final plans, the Dulwich option was rejected, with the western extension terminating at Clapham Junction instead.

Arguments were made for the line to be extended further south to Sutton, but estimates indicated that passenger usage would be so great that the line would be unable to take much traffic north of West Croydon

 and this option was not adopted.

Construction

The East London Line extension project was officially initiated by the Government on 9 October 2001, with construction of the northern extension due to begin in December 2001. However, it was held up when it came to light that the Grade II listed 19th-century Braithwaite arches in the former Bishopsgate Goods Yard were to be demolished as part of the project. Campaigners launched legal action against London Underground in an effort to prevent the demolition, but the project finally received legal clearance in the Court of Appeal
