Central Railway Station has buildings concentrated on its northern boundaries that are fed by large rail yards behind. Together they form part of the fabric of the city of Sydney and form boundaries to its inner suburbs. The location of this station is on land that has been in continuous government use since the commencement of European settlement. Various forms of public transport have radiated from this site since 1855. As part of the construction of the electrified city railway in the 1920s, the existing station was cut back to 15 platforms with new platforms built to the east of the existing station. As part of the project, platforms 10 to 15 were electrified, with platforms 1 to 9 following in 1956.The current 15 Sydney Terminal platforms run perpendicular to the main station concourse and all are dead ended with the buffer stop. They are arranged as seven double platforms and one single platform, each with an
awning, servicing a total of 15 tracks. Platforms 1–3 are for country and interstate services, while the remainder are for interurban services. Two further underground platforms were built as part of the
Eastern Suburbs Railway, bringing the total number of platforms in the suburban section to ten. Construction commenced in 1948 but the line was not finished until 1979. While the plans called for four platforms, two (for the Southern Suburbs line) were intended to be used in the future and have never been brought into service. They were for a time used for archival storage by the railways.
Metro platforms and Central Walk Construction began in 2018 on two new underground platforms as part of the
Sydney Metro City & Southwest project, and a new landmark underground concourse called Central Walk, which connects the suburban, intercity and metro platforms. Central Walk was partially opened in November 2022 and was fully opened in April 2023. Central Walk provides lift and escalator access to the suburban platforms, which previously had only lift and stair access. The metro platforms were built beneath Platforms 13 and 14, which were closed for the duration of construction. In November and December 2018, Platforms 12-13 and 14-15 were demolished. A temporary Platform 12 was erected in January 2019. The metro platforms opened on 19 August 2024. From opening, the long and tall escalators between Central Walk and the metro platforms are the longest in the southern hemisphere, overtaking the previous record of long escalators at Perth's
Airport Central railway station.
Indicator board in
Ultimo When opened, Central station had an indicator board with 22 vertical panels. It was replaced in June 1982 by computer screens with the original indicator board conserved by the
Powerhouse Museum. In June 2015, a new elevated indicator board was installed on the main concourse on the same sandstone base as the original board.
Devonshire Street Tunnel After Central was built in 1906, Devonshire Street, to the north of the old station, became an underpass, now called the
Devonshire Street Tunnel or Devonshire Street Subway. The underpass allows pedestrians to access the eastern "suburban" section from Railway Square and Chalmers Street. To the west, the tunnel continues under Railway Square and connects to
The Goods Line – the former
Darling Harbour railway line which has been converted to a park and pedestrian pathway to
Ultimo and
Darling Harbour.
Railway Square The western side of the Sydney Terminal building leads down to Railway Square, originally Central Square, at the junction of George and
Pitt streets. Although Railway Square no longer signifies the entrance to the interior of the colony, it has always channelled traffic from the southern parts of the city and out west to
Parramatta. From the building of the first railway terminus at Devonshire Street in 1855, it was an important focus for the arrival of country persons to the city and later commuters into the city. This was the last remaining carriage
shed at Central Station. The six rail lines that enter the shed were connected to the yard through tunnels at the end of Platform 1. The Yard was designed for locomotive-hauled trains. As this technology has gone out of use except for the
Indian Pacific and Special Trains the yard has little present functional use. With locomotive hauled trains the trains were marshalled for running in one direction. It has the locomotive at the head of the train and a brake van near the rear. This meant that trains when ending their journey had to be remarshalled before commencing their journey out of Sydney Station. The introduction of trains with driving positions at both ends of the train no longer require this process. As the station originally handled locomotive hauled passenger trains for suburban, country and interstate service this activity was considerable. Most of the steam loco facilities and trackwork has been removed. The decline in shunting and the removal of coal and water storage has seen a reduction in the level of activity in the yard. Although it has progressed through various configurations, the landscape has maintained the same ground level since 1856 with its final layout being enlarged in 1906 by the removal of some houses and the realignment of Regent Street to its present format.
Former Prince Alfred Sidings The Prince Alfred Sidings were formerly to the south of Platform 23 and on the eastern perimeter of the site, making up the boundary with Prince Alfred Park to the southeast. The Prince Alfred or "PA" electric car sidings were built only after the flyovers. Prior to the construction of the electric lines, the yard was a goods yard containing Produce and Goods Sheds as well as the first carriage shed. All have been removed from this precinct. The Yard is a small part of the original Sydney yard, of which a number of buildings remain which date from 1870. Later additional buildings are associated with the 1926 Electric Suburban System. The construction of the electric system reduced the width of the Prince Alfred Sidings, and trains within this yard needed to be protected because of vandalism. The Electric Sub Station is part of the 1926 electrification works and is linked with the sub station at the Sydney Harbour Bridge. It also contains air compressors for the operation of pneumatic points within the Yard and the City Circle Lines. A
retaining wall forms the boundary with Prince Alfred Park; it has been incorporated into the rear wall of the blacksmiths workshops. A number of mature trees are growing on the boundary, the largest being a Moreton Bay Fig at least 80 years old. ==Platforms==
