(ANSA) - LONDON, NOV 26 - A 24-hour strike on the underground is underway in London, in particular for the night-time storage lines, which is causing inconvenience and delays for people with indigenous people.
The Piccadilly Line - including Tube services to and from Heathrow Airport - and part of the CentralLine were shut down with the agitation launched by the RMT transport union.
Service is limited along other lines.
The mayor of London, Sadiq Khan, said he was "strongly upset" by the strike called for a union dispute over the night shift of employees of London Underground.
