It now sees fairly regular trains across the line except for the branch to the closed Newhaven Marine station.

These have now been removed or have become overgrown, as has the defunct Newhaven Marine station, which has been fenced off from the public.

The line between Newhaven Harbour and Seaford was reduced to single track to save costs in 1975.

Class 377 "Electrostars" are used on the line to transport passengers to Lewes and Brighton.

The normal off peak train service on the line is two trains per hour between Brighton and Seaford calling at London Road, Moulsecoomb, Falmer, Lewes, Southease (1tph only), Newhaven Town, Newhaven Harbour (1 tph only), Bishopstone and Seaford.
