The station served the suburb of Knockmore in Lisburn, County Antrim, Northern Ireland.
"Down" trains travelling from Portadown to Belfast could not serve Knockmore as it was the middle line with no platform.
In 1968, the UTA was replaced by Northern Ireland Railways, which reopened the Antrim branch and rerouted all Londonderry line services via Knockmore.
Instead of using a crossover as per the original setup, a 3rd line was laid directly from the former junction to Lisburn station.
[6] Then 30 April 1956 the line via Dromore to Banbridge and Newcastle, County Down was closed under the auspices of the Ulster Transport Authority.
