Planned Changes to Train Times

Details of planned engineering works on the Southern network.

  • To maintain and improve the railway, Network Rail carries out regular planned engineering works on the Southern network
  • Work normally takes place at weekends or after 10 pm – but occasionally services are impacted at other times
  • Information will be available here as soon as it is available
  • Please check before travelling, and see our live departures and arrivals for up-to-the-minute information

Planning a journey or buying a ticket in advance?

Normally, the timetable for any particular day is confirmed 12 weeks in advance. For a temporary period Network Rail isn’t able to do this, instead confirming timetables closer to the date of travel. More detailed information is available here.

Wherever possible we've highlighted those affected journeys in our journey planner using a warning alert.

To help plan your journey in advance, we have worked with our industry partners to upload the dates and locations of planned engineering works into the engineering works calendar below.

You can still book tickets in advance and our Advance fares are available up until the day before travel. If you buy a ticket in advance and the journey is changed then you can either check how the service has been changed and continue to travel or apply for a refund.

Always check before you travel using our Journey planner, National Rail Enquiries or download our On Track App.
