Due to snow rail operator Southern will be operating an amended timetable for today Friday (January 18).
Trains will not split or join at Haywards Heath or Horsham stations.
This will mean passengers who travel on the East and West Coastways into and out of London may be affected.
Passengers who hold Advance tickets will be able to use them on the train before or train after, if their booked train does not run as a result of the changes.
For train times visit the National Rail website or call National Rail Enquiries on 08457 48 49 50.
And, if you are out and about in what promises to be a winter wonderland in Crawley, please send us your pictures to email@example.com.
