There will be no trains on the Waterloo to Alton and Portsmouth lines on Friday, June 2, because of strike action.

The nationwide strike by RMT union members will severely reduce the number of trains South Western Railway (SWR) can run.

A significantly reduced service will operate between 7am and 7pm only and large parts of the network will be closed.

This includes the Waterloo to Alton line, serving local stations including Farnham, Bentley and Alton, and the Portsmouth line, serving Godalming, Witley, Haslemere, Liphook, Liss and Petersfield.

The following services are the only to operate across the SWR network on June 2:

Customers are advised to only travel if their journeys are absolutely necessary. Journey planners for Friday, June 2 will be up to date on Saturday, May 27.

Customers travelling to Epsom Downs Racecourse for Epsom Ladies Day are advised that there will be no services in the Epsom area.

Strike action will also affect other train operators and customers are advised to check their entire journey before they travel at nationalrail.co.uk

Industrial action is also being taken by ASLEF union members on Wednesday, May 31, and Saturday, June 3.

This will affect SWR’s network-wide depot drivers, who bring trains in and out of service, as well as drivers on the Island Line – but there no direct impact on Alton and Portsmouth line services is expected.

Steve Tyler,  SWR’s planning and performance director, said: “I’m sorry to say that due to strike action we will be forced to make changes to our services on Wednesday, May 31, Friday, June 2, and Saturday, June 3. We are still working to confirm our services but able to advise customers of what to expect.

“The majority of our network will see a normal service on Wednesday, May 31 and Saturday, June 3, but there will be some areas where a reduced service will operate – suburban routes, on the West of England Line and in the Romsey area. There will be no service on the Island Line on these two days.

“Services will also start at the later time of 7.30am on Saturday, June 3. On both days of ASLEF strike action, in the event of disruption, services may be subject to short notice delays and cancellations. Customers should check before they travel.

“On Friday, June 2, we will operate a significantly reduced service on a limited number of lines. Train services will only operate between the hours of 7am and 7pm. For this reason, we are asking customers to only travel if their journeys are absolutely necessary.

“We’re sorry for the disruption that our customers will experience and we strongly advise they check before they travel.”
