For a period up to 1973 hourly direct services to London Victoria left from platform 2. By 1978 direct services ran only in peak hours, the fastest taking 98mins to reach Victoria, slower than the fastest 81mins, and off-peak half-hourly 94 mins to London St Pancras International 35 years later, which require a change.
After the withdrawal of the Class 411 Ceps, services from August 1998 to December 2006 were operated by the Class 508. From the December 2006 timetable change, the two coach Class 466 are used.
Since January 2015, Southeastern has operated two direct services from Sheerness-on-Sea to London Victoria in the morning peak. These services do not stop at Sittingbourne by using the third side of a triangle junction that links the Sheerness Line to the Chatham Mainline. There are also two return services from London Victoria to Sheerness-on-Sea in the evening peak. These services are formed of Class 465s and Class 466s working in multiple. This has resulted in Platform 2 being brought back into use.
