THE Central Line is suspended between Hainault and Woodford stations this morning as commuters face a fourth Tube strike of the year.

Wanstead and Gants Hill stations are closed and a special service is operating on the Central Line between West Ruislip/Ealing Broadway and White City, and between Hainault/Epping and Holborn.

All other lines are running with a special service, while the Circle Line has been completely suspended.

Transport for London says 80 per cent of stations are open, and 45 per cent trains are running.

Members of the RMT and TSSA unions started a 24-hour walkout at 6.30pm.

But London Underground bosses have warned union leaders their actions “will achieve nothing whatsoever”.
