Until 2006 both platforms were only 4 coaches long. Since then the platform for trains towards Pulborough has been extended to take 8 coaches and more recently the London-bound platform has also now been extended to 8-car length.[2]
In the peak hours, the station is served by a single service between Bognor Regis and London Bridge.
On Sundays, there is an hourly service but southbound trains divide at Barnham with an additional portion of the train travelling to Portsmouth Harbour.[citation needed]
