Outer London rail orbital opens

A 7-mile long £75m rail link has opened that joins Surrey Quays in the south-east with Clapham Junction in south-west London.

The orbital, which London Mayor Boris Johnson called the "M25 of rail", will mean cheaper fares and cut congestion by avoiding central London, according to Transport for London.

But critics feel those bound for central London will be "worse off" as they will lose the links which were earlier provided by the South London Line.

It takes over South London Line services between London Bridge and Victoria via Denmark Hill and Peckham Rye. The service was withdrawn as Thameslink undergoes an upgrade.

The Overground now goes through 21 of London's 32 boroughs, and the orbital will allow passengers to go on its different routes via Willesden Junction, Clapham Junction, Highbury and Islington and Gospel Oak stations.

Four trains an hour will run on the route, stopping at Queens Road Peckham, Peckham Rye, Denmark Hill, Clapham High Street and Wandsworth Road, carrying up to 12.3 million people a year.

It'll take tens of thousands of people out of the middle of London. The number of journeys on the Overground per day is more than 300,000. That's going to go up by about 25,000 every day.

The new stations connecting Surrey Quays to Clapham Junction are:

Queens Road Peckham

Peckham Rye

Denmark Hill

Clapham High Street

Wandsworth Road

This is the final stage of a £1.5 billion investment to improve the London Overground.

Now the extension between Surrey Quays and Clapham Junction is open, the Highbury & Islington to West Croydon/Clapham Junction line will have trains running up to every 15 minutes between:

Highbury & Islington and Clapham Junction

Highbury & Islington and Crystal Palace

Dalston Junction and New Cross

Dalston Junction and West Croydon

This means that trains will run every 3 to 5 minutes between Dalston Junction and Surrey Quays.
