London faced major travel disruption on Tuesday after some Underground train drivers went on strike over changes to working hours. The walkout by members of the National Union of Rail, Maritime and Transport Workers went ahead after talks with Transport for London failed. Another full-day strike is planned for June 4.
There was no service on the Circle, Piccadilly and Waterloo & City lines. Parts of the Metropolitan and Central lines were also shut. Other Tube lines were running with severe delays.
