The railway line between Letterston and Goodwick (the latter station being renamed Fishguard and Goodwick in 1904) opened on 1 July 1899 as an extension of the line from Clynderwen via Rosebush, but initially there were no intermediate stations.

[2] Jordanston Halt, situated between Letterston Junction and Fishguard & Goodwick 284 miles 8 chains (457.2 km) from Paddington (measured via Rosebush), opened on 1 October 1923.

[3][4] The halt was close to the top of a 1 in 100 gradient sloping down towards Letterston Junction.

The facilities were basic: the platform surface was of cinders no higher than the rails - portable steps were used to board trains; and there was a small wooden shelter.

In July 1949, on the newer line via Clarbeston Road, there were seven trains towards Fishguard Harbour, and eight to Clarbeston Road; the first train of the day in each direction ran to or from Neyland.
