The station is 1 mile 74 chains (3.1 km) from Brighton on the West Coastway Line.

Dyke Junction Halt was opened in 1905[1] by the London, Brighton and South Coast Railway with short wooden platforms.

It is situated just east of the former junction with the branch line to Devil's Dyke, which opened in 1887 and closed in 1939; the layout and curvature of certain roads and buildings immediately north-west of the station indicates where the branch ran.

The station was staffed during peak hours until approximately 1990, after which the hut which served as a ticket office was demolished.

When Sectorisation was introduced, the station was served by Network SouthEast until the privatisation of British Rail.
