From May 20 we'll be making changes to some train times on our network.  This will replace our current winter timetable.

We strongly encourage you to check your journey before travelling.  For more information please visit our journey check page here or speak with a member of station staff.

Spring Weather Conditions

Spring weather can often see high temperatures rapidly followed by significant rainfall. This presents unique challenges to running trains, particularly in areas prone to flooding.

Our Network and Trains

We operate one of the most complex commuter rail networks in the UK. We operate nearly 1,700 trains a day, covering more than 600 miles of track and serving nearly 180 stations across South West London, Surrey, Hampshire and parts of Wiltshire, Berkshire, Devon and Somerset. The track infrastructure we use – as well as the signalling, points and third rail power supply - is owned, operated and maintained by our partners at Network Rail. Together, we run a dedicated 24-hour, 7 day-a-week operational Control Centre where we work to keep trains on our network running as smoothly as possible, as and deal with any disruption that occurs. We also keep you updated with the latest information on our services here.

Most of our trains – as well as trains operated by other operators south of the River Thames including Southern, Southeastern and Thameslink/Great Northern – are powered by electricity from a track-level third rail DC electrical system. This relatively low-cost system was introduced in the 1920s and 1930s and is different to the system used by trains which draw power from overhead lines. During normal weather conditions, the third rail system works extremely well and we are able to deliver a punctual service to our customers. In addition, we use a small number of diesel trains largely on the London to Salisbury and Exeter route which run without any requirement for electrical power supplies to move them.
