Wynyard railway station, Sydney

Wynyard railway station is a heritage-listed underground commuter rail station located in the north-west precinct of the Sydney central business district, in New South Wales, Australia. The station opened on 28 February 1932 to coincide with the opening of the Sydney Harbour Bridge and provides a direct link to the Sydney Airport international and domestic stations.HistoryThe station opened on 28 February 1932. Wynyard was originally constructed with six platforms (the existing four platforms are still numbered from 3 to 6), with platforms 1-4 located on the upper level and platforms 5 and 6 on the lower level. The original intention was that Platforms 1 and 2, located adjacent to platforms 3 and 4, would eventually serve the eastern pair of railway tracks across the Harbour Bridge. In the interim, they were used as a terminus for North Shore tram services on Sydney's tram network, a service that operated over those tracks from the bridge's opening in 1932 until 1958. A feature of these lines was Australia's only underground tram terminus.After tram services were withdrawn, platforms 1 and 2 were walled off from 3 and 4, and the space converted into an underground car park, which continues to function as such to this day. The eastern tram tracks on the bridge were replaced by two extra road lanes as part of the Cahill Expressway. The disused tunnel and ramp that formerly connected the station to the eastern tram tracks can still be seen, mirroring those still in use to the west of the bridge. On 22 January 1956, the lines from platforms 5 and 6 were extended to Circular Quay as part of the City Circle.
