On Wednesday 27 & Thursday 28 December
All four tracks at Earlswood will be closed therefore the following services will be in place:
 
• We will operate a train every ? hour between London Victoria and Gatwick Airport in 90 minutes and Brighton in 120 minutes. This train will operate via an alternative route and provide a connection at Horsham for stations to Chichester and Worthing, and a connection at Three Bridges for stations to Lewes and Eastbourne.
• There will be a bus provided from Redhill serving stations to Three Bridges to cater for passengers from London Bridge, East Croydon and intermediate stations. Please note the bus will only serve Gatwick Airport south bound, passengers from Gatwick Airport should travel by train to Three Bridges to catch the bus.  Passengers from Croydon can avoid the bus if they use West Croydon station and change at Sutton to pick up the diverted train.
• We will operate a train every ? hour between London Victoria and Redhill to serve the intermediate stations.
 
To accommodate diverted trains between London Victoria, Gatwick Airport and Brighton, it has been necessary to reduce train services Between London Victoria, Streatham Common, West Croydon, Sutton, Epsom and Dorking.
Boxhill, Holmwood, Ockley and Warnham will be served by alternative road transport.
 
Friday 29 and Saturday 30 December
Two of the four tracks at Earlswood will be closed but not affecting platforms. Therefore a reduced Saturday train service will operate but will be able to serve all stations, and so there will be no need for replacement buses.
 
The train service and bus replacement details are currently being finalised and will be on our website nearer the time.   
 
Other train operators using this line will also be running alternative services, please check their websites for more details nearer the time.
