[5] Lea Bridge railway station is located a short distance to the south of the junction on the Stratford line.

[7] The proposal has the support of Waltham Forest London Borough Council;[3] Jennette Arnold, Labour Party politician and member of the London Assembly representing the London Boroughs of Hackney, Islington and Waltham Forest;[8] Stella Creasy, Member of Parliament for Walthamstow;[8] the Walthamstow Liberal Democrats, the Chingford and Woodford Green Liberal Democrats, the Chingford and Woodford Green Labour Party;[4] and Railfuture, an independent organisation campaigning for better rail services in the UK.

[4] Transport for London (TfL) ran a study on the feasibility of reopening the curve for 2016 that produced a result with a benefit-cost ratio ranging between 8:1 and 14:1 depending on the length of trains involved.

[3] In 2007, the Greater Anglia Route Utilisation Strategy published by Network Rail suggested that construction of the curve could be possible by 2019 or later.

[10] In January 2017 the Mayor of London, Sadiq Khan, responded to a petition for the reinstatement of the curve, stating that whilst TfL "supports the principle of improving connectivity between Waltham Forest and Stratford", it would not be possible due to expenses involved in purchasing non-railway land and constructing additional platforms at Stratford.
