Update 10.55

London Underground trains are only running on a few suburban sections on the last day in the present series of RMT strikes.

Today is the second day that signallers have walked out, while other staff were on strike on Sunday, Monday and Wednesday. The RMT has warned that more strikes could lie ahead.

Services are suspended on most Underground lines except the Piccadilly between Acton Town and South Harrow, the District between Whitechapel and Upminster, and the Metropolitan between Baker Street and Watford.

There are also no trains for a second day this week on the Docklands Light Railway. because of a separate dispute, while Chiltern Railways cannot run between Great Missenden and London Marylebone because it uses London Underground tracks between Amersham and Harrow-on-the-Hill.

Other TfL routes, including the Elizabeth line and all London Overground lines, are reporting a ‘good service’.

There has been no sign of a breakthrough in the deadlock between the RMT and Transport for London which has led to this week’s walkouts.

The RMT is calling for a three-hour reduction in the working week to 32 hours, which TfL has dismissed as unaffordable, saying it would have a price tag of £200 million, while TfL is urging the union to hold a new ballot over a pay offer of 3.4 per cent.

Last night RMT general secretary Eddie Dempsey warned that more strikes could follow, and he has urged the Mayor of London Sir Sadiq Khan to intervene by attending a summit.

Speaking to the TUC congress in Brighton, Mr Dempsey said: ‘I’ve got a message for the Mayor.

‘Instead of going on social media, instead of the old tired clichés, telling trades unionists to get round the table, you’re the Mayor of London, you’re the Chair of TfL.

’Stop going on social media, invite us to the meeting, let’s have a discussion, because I want to know what is going on in London.

‘We take no pleasure in causing disruption but we make no apology for fighting for our members. So if the mayor has any sense, he will reach out to us.’

The Congress unanimously supported the call for a summit.

Services are expected to return to normal tomorrow, but TfL is warning of possible disruption until about 09.00.
