East London Line


To improve connections around London and accommodate the increasing number of passengers, an extension to the East London Line was needed to be integrated into the existing transport network.

AECOM became involved in 2010 with the Program Cost Consultancy team of experts delivering cost management services. As lead designer with the Balfour Beatty/Carillion Joint Venture AECOM provided technical support and design services including detail design for new stations, buildings, civils and structures works including architecture, landscaping, geotechnics and trackside power.

Extensions to the existing East London Line in both north and south directions connected the line with existing rail services and became part of the London Overground orbital network. To the north, the new line extends to Dalston Junction where it connects to the North London Line. This reuses an existing viaduct, crossing the tracks into Liverpool Street station on a new bridge near Shoreditch, with four new stations constructed on the route. To the south, a new flyover at New Cross Gate connects the line to the Network Rail Brighton line, allowing services to run south to West Croydon and Crystal Palace.
