Can I get compensation if I choose not to travel?

South Western Railway says: "If you have already purchased daily tickets for Wednesday  27 July, and you decide not to travel because the service you originally intended to travel on is no longer running or has been retimed, you will be able to claim a fee-free refund.

"Alternatively, you can use the same ticket to travel the day before or up to and including 2 August."

Will everything run again as usual on Thursday?

South Western Railway said “significant disruption” is also expected on Thursday, July 28, when there will be a late-starting service, with first trains operating much later than usual.

Services are set to be busier than usual. 

Customers have been told they should check before they travel. 

What has South Western Railway said?

South Western Railway’s managing director, Claire Mann, said: “The scale of the planned industrial action limits the number of trains we can run and routes we can serve, resulting in the severely reduced service we are able to operate on the strike day.

“We urge customers to only travel by rail if absolutely necessary on Wednesday 27 July, and to check before you travel on Thursday 28 July, as we will be running a late-starting service due to the disruption of the strike the previous day.

“We are sorry that strikes will again cause such disruption, and we are grateful to our customers for their continued cooperation, patience, and understanding as the rail industry works to end this damaging nationwide strike action.”

Will there be more strikes after this one?

The RMT union has announced further strikes will be taking place on Thursday, August 18 and Saturday, August 20.

South Western Railway said it will be publishing service level information for this.
