Construction began in 2006 on the initial £1 billion phase of the
project, which involved converting the under-utilised Underground line
from Shoreditch to New Cross Gate and New Cross to heavy rail
standards, with extension south to Crystal Palace and West Croydon, and
north to Highbury & Islington. New stations have been built at
Shoreditch High Street, Hoxton, Haggerston, and Dalston Junction.

The full service of four trains per hour between Dalston Junction and
West Croydon will begin on May 23. The completion of a £50 million
connection between Dalston Junction and the North London line next year
will allow services to be extended to Highbury & Islington. Around
30 million passengers are expected in the first year, rising to 40
million when this extension is completed.

A further £75 million extension is planned that will connect the ELL at
Surrey Quays with the West London Line at Clapham Junction. This line
will open by 2012.
