Engineering work over the Easter weekend means no services will run between East Croydon and London Victoria.
The normal off peak service will be running from Uckfield and Crowborough with slight route changes.
On Friday, Saturday and Monday trains will start and finish at East Croydon, where you can connect to an onward train to London Bridge and London Overground Services.
On Sunday, trains will run to Oxted and you can change here (or at Hurst Green) for a train to London Bridge.
