Members of the RMT union have planned a number of strikes this month over the role of train guards, possibly causing disruption to rail services on some of South Western Railway's busiest routes.
The strikes are being held over the following two Saturdays as well as a 48-hour walk-out at the end of the month. It follows the failure of talks earlier this week.
SWR says it has offered a similar deal to one accepted by the RMT on Greater Anglia, but this is denied by the union.
South Western Railway says it has put together plans to run a full timetable on the chosen dates.
The 24-hour strikes that have been planned from midnight to 11.59pm on:
- Saturday 4 August 2018
- Saturday 11 August 2018
- Saturday 18 August 2018
A 48-hour strike has also been planned from midnight to 11.59pm from Friday 31 August to Saturday 1 September.
