Sydenham railway station is a heritage-listed railway station located on the Illawarra line, serving the Sydney suburb of Sydenham in New South Wales, Australia. It is served by Sydney Trains T3 Bankstown, T4 Illawarra and T8 South services. It was designed by the New South Wales Government Railways and built from 1884 to 1962, with William Robinson having built the original 1884 buildings. It was added to the New South Wales State Heritage Register on 2 April 1999. History Sydenham Railway Station was built on a duplicated line from Illawarra Junction to Hurstville and opened as Marrickville railway station on 15 October 1884. The western platform contained a major 3rd class brick station building having a detached toilet block at each end separated by walled courtyards while the eastern platform contained a large 2nd class brick station building. The station obtained its present name on 19 January 1895 with the opening of the Belmore branch line. In 1896, Sydenham became a junction station with the opening of the Bankstown line with the current platforms 3 and 4 opened. The impressive station was obviously intended to serve the Marrickville township proper but it was distant, surrounded by industrial and rural estates and only grew as a station by reason of the need to cope with the branch line junction. In 1907 the line from Edgeware Road to Sydenham was quadruplicated to serve the Belmore to Bankstown extension when it opened in 1909. This resulted in confining both buildings on island platforms so that passengers had to reach the platforms by an extended footbridge, whereas the substantial platform building on the current platform 2/3 island previously faced the street. A new timber overhead booking office on a steel support frame was built between Platforms 3 and 4 and steel footbridges were eventually extended to all platforms 1914. To provide for the proposed Eastern Suburbs railway line, two additional tracks were put in so that in 1925 the brick standard island platform building on Platform 6 was built. In 1926, the lines were electrified at Sydenham. Soon after in 1927, the refreshment room was opened for factory workers in the area. As the additional tracks were never utilised for the Eastern Suburbs Railway, they have been mainly used for the Bankstown line trains. In 1963, a brick parcels office building was constructed on Platform 1 but closed in the late 1980s. It had
