This has always baffled me. There appears to be the remains of a bridge abutment by the junction of Brixton Station Road and Barrington Road.
The aerial view seems to confirm that there was a line heading to the bridge abutment, but it would have to then be elevated above the road as there's nowhere for it to go.
I can't see anything on the old 1870/1894 maps - the empty abutment looks much like today.
Might it be an extension that never got built ? Or maybe space for platforms for an extended Brixton East station scheme?
