South West Trains
Customer advice and information during hot weather
On hot days, rails in direct sunshine can be as much as 20 degrees centigrade above air temperature, due to exceptionally high temperatures our engineers monitoring rail conditions may need to introduce speed restrictions to trains (lower the travelling speed limits) over some sections of the railway line across our network. If this occurs on your route, trains may have to run slower than usual along certain parts of the railway and journeys may take slightly longer.
We urge you to check our website, and Twitter, @SW_Trains before travelling for the latest information and to listen out for announcements on trains and at stations.
Here are a few tips for keeping comfortable in hot weather:
  • Carry water with you.
  • Don’t board a train service if you feel unwell.
  • If you feel unwell please get off at the next stop and seek help from our staff.
  • Avoid pulling the passenger alarm between stations, as help can be more easily obtained with the train in a platform and not standing stationary on a railway line.
