In a reply to a question by Assembly Member Val Shawcross, published today, Johnson went on to say that a new station down the line at East Brixton would cost up to £50million, but that benefits would be “much lower”due to its distance from the town centre.
Earlier this year, Lambeth Council commissioned a £25,000 feasibility study into the opportunities for a new stop on the line from from Clapham Junction to east and north London.
Carriages on the line currently sail high above Brixton Road without stopping, and Transport for London have previously said that a stop at Brixton would be too expensive as the line is “elevated, curved and on a gradient.”
In a written response published today, Johnson wrote: “The study identified the significant benefits that a high level station would have but found that the major infrastructure constraints and construction difficulties remain. The estimated cost of a new station is at least £80m and could be as high as £120m. This means that a station here is unlikely to be affordable, so alternative locations were reviewed.
“A new station at East Brixton appears more feasible, but this still has a high cost for a new station, estimated between £30m and £50m, and would have much lower benefits as it is further from the town centre.”
He added: “TfL will continue to provide support to Lambeth Council as they further develop the case for new stations and improvements to existing stations.”
The London Overground Line links Clapham Junction with Highbury and Islington, via Peckham, Surrey Quays, Whitechapel and Shoreditch. This stretch of line was opened in December 2012.
