Significant disruption expected from now until the end of the month

The RMT have coordintated strikes with ASLEF

July 19, 2023

The London Underground network is likely to be affected for six days by strike action by two rail unions beginning on Sunday 23 July.

The action will impact different lines on different days and severe disruption is expected on the Tube up until Saturday 29 July.

London Underground has issued the following advice about strike day services

Sunday 23 and Monday 24 July – London Underground services will close early on Sunday 23 July with customers advised to complete their journeys by 7pm. On Monday 24 July, a good service is expected by late-morning.

Tuesday 25 and Thursday 27 July – Little or no service expected across the London Underground

Wednesday 26 and Friday 28 July – No service expected across London Underground including Night Tube

Saturday 29 July – Tube services will start later than normal with a good service expected by midday

Elizabeth line and London Overground services, which are not directly affected by the strikes, will be busier than usual and queuing systems may be in place. These services are expected to run as normal but the closure of Tube stations may mean some services will be unable to stop at all stations or run to their normal destination. Buses will run as normal but also may be busier than usual.

Glynn Barton, TfL's Chief Operating Officer, said, “We are disappointed that the RMT, ASLEF and Unite unions have announced strike action. We are continuing to talk with trade unions to discuss the issues and seek a resolution.

"There are no current proposals to change pension arrangements. Although we are discussing with union colleagues a range of proposals to change how London Underground operates, no employee will lose their job or be asked to work additional hours.

“We urge the trade unions to call off this action, but if it goes ahead customers should check before they travel as there will be significant disruption on the Tube across the week.”

The tube’s management says that there are currently no proposals to change pension arrangements.

There are also national rail strikes on 20, 22 and 29 July.

On South Western Railway (SWR) services have already been reduced in the run up to the strikes by an ASLEF overtime ban

On Thursday 20 July, nationwide strike action by members of the RMT union will mean a significantly reduced service will operate on a limited number of lines. Trains will only operate between the hours of 7am and 7pm, with last trains departing at around 5pm.

Two trains an hour will run between Hounslow and Waterloo serving stations such as Brentford, Isleworth, Kew Bridge and Chiswick.

Stations such as Putney, Barnes and Wandsworth Town will be served by an additional two trains per hour going to Windsor and Ascot. Wimbledon will have eight trains an hour with services from Woking, Southampton and Basingstoke stopping.

Following the strike action on the previous day train services will start later than usual, at around 7.30am, on Friday 21 July. A reduced timetable will again operate due to the continuing overtime ban by members of the ASLEF union.

On Saturday 22 July, the operating hours on SWR will be the same as for the strike on Thursday but the number of trains will be even more limited and local trains will terminate at Twickenham and Hounslow. On Sunday 23 July a small number of services are expected to be cancelled.

Stuart Meek, Chief Operating Officer at SWR said, “We’re sorry that customers will again face disruption due to industrial action by the ASLEF union and strike action by the RMT union.

“Anybody planning to travel on days affected by the ASLEF union’s industrial action should check their whole journey before they set off and be aware that services are likely to be busier than usual.

“As with the last ASLEF overtime ban, instead of making numerous short-notice amendments and cancellations to our standard timetable, we will operate an amended timetable that we have a high degree of confidence we can reliably and safely deliver. We hope this will give our customers greater certainty when planning their journeys.

“On days of strike action by the RMT union we are sorry to ask that customers should only travel if absolutely necessary. We have worked hard to improve our service offering during RMT strike action and are pleased to confirm that we will operate services to and from Ascot on Thursday 20.”
