Thank you for your email regarding the opening times of the East London Line extension.
I can confirm the line from Shoreditch High Street to Dalston Junction is due to open in June 2010. The line from Dalston Junction to Highbury & Islington is scheduled to be open from February 2011.
I have attached an image of a map which confirms what I have just advised.
I hope this information proves useful. If you should have any further questions please don't hesitate to contact us.
