Just a little history for anyone that is interested: Dalston Junction Railway station opened in 1865!
The station was first opened on 1 November 1865 by the North London Railway on its "City Extension" from the North London Line to Broad Street in the City of London. It had three island platforms with four through lines joining the west side or the North London line, and two joining the east. The station had no overall roof.
The line to Broad Street, and the station, closed on 27 June 1986. However, the location at the corner of Kingsland High Street and Dalston Lane retained the name Dalston Junction on road and bus signs throughout the period that the station was closed. The rebuilding of the station for the London Overground network began with site clearance in early 2005. The station was opened by the Mayor of London, Boris Johnson, on 27 April 2010, with services only running south at that time. Since 28 February 2011, trains have also continued north beyond Dalston Junction, taking the relaid west curve north of the station to Highbury & Islington. One other interesting little fact (to me at least), the new station has the exact same footprint as the original 1865 station.
