UNDERGROUND services are set to be hit by strike action during two 48-hour walk-outs by staff.

The strikes have been planned by the RMT and TSSA unions on the London Underground over plans to modernise the service which will see widespread job loss and ticket office closures.

The first strike will begin at 9.30pm tomorrow (Feb 4), with services not expected to return to normal until Friday morning.

The second will take place at the same time next week.

London Underground managing director Mike Brown criticised the action.

He said: “LU is consulting with trade unions and staff over its vision for the future of the Tube, which includes a new 24-hour night Tube service at weekends and more staff visible and available in public areas of Tube stations to help customers buy the right ticket, plan their journeys and to keep them safe and secure."

He called the union ballots ‘poorly-supported’, saying that only 30 per cent of members voted to strike.

“The union leaderships have nonetheless instructed their members to carry out four days of strike action,” He added.

There will be disruption to journeys on Wednesday and Thursday, when Tube services will start later and finish earlier than normal with trains expected to run from around 7am until 11pm.

The Central line will be affected with trains running from Epping to Leytonstone every 12 minutes in both directions.

Trains between West Ruislip and White City will run every 15 minutes in both directions.

Victoria line services will run between Seven Sisters and Victoria every five minutes in both directions but these trains will not stop at Warren Street.

People are being advised to top up their Oyster card in advance and consider other modes of transport including bus travel and cycling.
