Commuters using Brixton station on Tuesday are likely to be hit by a strike by Victoria Line drivers.
Members of the RMT union will take action from 9pm Tuesday (September 24) until 3am the next day in the row about overtime.
Drivers claim they are being forced to work overtime and that London Underground (LU) are failing to hold meetings about it.
But LU told the BBC it had held meetings, and said the response to the RMT ballot was poor: “Less than half of those balloted chose to vote in any way, and just 39% of those balloted have voted for industrial action.
“If the union feels there are still issues to discuss then they should keep talking to us so that things can be resolved properly.”
It is not yet known how the strike would affect services at Brixton Station and along the Victoria Line.
