More than one million commuters are set to face delays again as another 24-hour Tube strike descends.

The strike, due to begin tonight (Wednesday January 24) at 9pm when members of the RMT union stage a walk-out, was triggered over the “forced” transfer of eight drivers to different depots.

London Underground wants to move the drivers from the Central line depot at Leytonstone to the District line at Earls Court.

Transport for London (TfL) has said there is likely to be no service on the Waterloo and City line, no Central line service east of Leytonstone and “less frequent trains” on the rest of Central.

TfL warns that all other services will run as usual but are likely to be a lot busier.

The Central line is used by 800,000 passengers each day, while more than 32,000 use Waterloo and City.

Steve Griffiths, chief operating officer of London Underground, said: “This strike is completely unnecessary.

“Like any responsible transport authority we regularly examine how we can provide the best possible service to customers and to achieve this sometimes we need to move staff from locations where they are under-utilised to where they are really needed.

“We have agreements with the trade unions to enable us to do this.”

Mick Cash, general secretary of RMT, said: “Let us be in no doubt, if LU are allowed to get away with this move on the Central Line they will start shunting drivers around the combine at the drop of a hat regardless of the consequences.

“Our members will be sent from pillar to post to plug gaps that are solely down to staffing shortages.”

Nearly 900 staff have been go and ticket offices closed.

A 24-hour Tube strike earlier this month over ticket office closures shut down much of the network, causing major travel disruptions and the closure of Clapham Junction station.
