From the Wikipedia page [1]
East Brixton railway station was a railway station on the South London Line from London Victoria to London Bridge. It opened as Loughborough Park in 1866 then was called Loughborough Park and Brixton from 1870, before it was finally renamed East Brixton in 1894.
The station consisted of two platforms with wooden buildings on a viaduct next to the bridge over Barrington Road, near Coldharbour Lane.
Over the years the station became progressively neglected and lost passengers from 1971 when Brixton tube station, the southern terminus of the new Victoria Line, opened nearby. With declining passenger numbers and the station requiring extensive repairs to the wooden platforms and buildings it was decided that the expense was not justified. There was a fire in 1975 which temporarily closed the station but the station reopened and was finally closed on 5 January 1976. The platforms and its buildings were demolished shortly after closure. Nothing now remains of the station at track level: there are some arches and windows in the viaduct of the still used line.
