This was a passenger terminus. It was the first station in Kilmarnock and opened in 1818.
It closed to passengers on 04/04/1843 according to the Glasgow and South Western Railway Association handbook.
The depot was near Kilmarnock House, owned by the Duke of Portland, just off St Marnocks Street.
The depot was closed between 1846 to 1847 for re-gauging. Following this it re-opened as a coal depot renamed as St Marnocks. A siding is shown on the 1859 OS map, curiously approached from the buffer end, the east. The siding was on the south side of St Marnock Street with a short access road providing access to a coal yard (now Ellis Street).
The portion from St Marnocks Junction to the original terminus is shown as a tramway on subsequent OS maps. This was to be cut back to the St Marnock Mineral Depot close to the junction.
With the closure being so very long ago little remains, except some rather eccentric boundaries of gardens.
