The station is located on the Seaford branch of the East Coastway line, 56 miles 51 chains (91.1 km) down the line from London Bridge.[1] The line reduces from two tracks to one immediately south of the station en route to Seaford.
There are two platforms at the station, joined by a footbridge. The station is managed by Southern, which operates all passenger services.
Newhaven Harbour is one of two stations serving the town of Newhaven, alongside Newhaven Town station less than half a mile (0.8 km) to the north. A third station in the town, Newhaven Marine, operated passenger services until 2006 and formally closed in October 2020.[2] Newhaven Harbour station is located on the south side of the town, adjacent to the Port of Newhaven freight terminal and nearby industrial estate.
Despite the station's name, it no longer serves the passenger ferry terminal − this was taken over by Newhaven Marine station, until the terminal was moved to a site next to Newhaven Town.[3]
In 1879, the port was redeveloped, constructing a new east pier and building a new wharf on reclaimed land, which could be run independently of tide times.[5] The station was renamed to Newhaven Harbour on 17 May 1886 when a station to the south, known as Newhaven Harbour (Boat Station), opened to serve the new boat train terminal.[6][7]
This service increases to 2 tph during peak periods. Two services on weekdays (one in the middle of the day, and one in the evening) terminate here and reverse using the reversing siding at Newhaven Marine.
* In addition to the Enterprise inter-city service. Newry had a limited week-day commuter service all stations to Dublin, provided by Iarnród Éireann. This ended in Sept 2024.
