Phase 1a extension of the East London Line (ELL) scheme was to reinstate the Dalston Curve which was closed in the 1980s. This allows the ELL to run alongside the North London Line alignment, adding an extra track to the three existing ones.

Tony Gee was originally employed to carry out detailed design of seven covered way structures. This was later extended to include track drainage (including a pumping station), UTXs, permanent way design (both slab and ballasted track form), strengthening of an existing bridge deck, substation civils, cable management systems, signage and signal bases.

Meeting stringent client requirements for the final fit out of the curve, which included a substation and extensive cable management systems, called for a good deal of lateral thinking. As designer, Tony Gee undertook a leading and challenging role in coordinating the design with the various subcontractors, ensuring that the track slab met with specific noise and vibration requirements, very tight clearances and interfacing with other disciplines.
