Central Line Tube passengers hit by Aslef strike
Commuters and visitors in London have been hit by major disruption as some Tube drivers strike.
Members of the Aslef union who work on the Central Line walked out at 00:01 BST for 24 hours.
During Friday morning's rush hour, there was no service between White City and Leytonstone and severe delays on the rest of the Central Line.
There was also no service on the Waterloo and City Line. Up to a million people use the lines daily.
Extra buses were laid on and Transport for London "ambassadors and volunteers" were on hand to give information to travellers.
Aslef's Finn Brennan said the dispute was about "respect" for drivers and putting a stop to a "bullying culture".
He said the strike was being "solidly supported", adding: "This dispute has been brought about by management intransigence on a range of issues, but at its heart is management's refusal to treat drivers with the respect and dignity they deserve at work."
London Underground operations director Nigel Holness said: "Despite some progress being made during talks, Aslef leadership have decided to press ahead with this unnecessary strike action and disrupt customer journeys this morning.
"Our staff and volunteers are working hard to keep London moving and I would advise our customers where possible to plan ahead and check before you travel."
A further strike is planned for next month if the dispute is not resolved.
