formed in seven island platforms, all facing two lines except Platform 1 and Platform 10 which both face single lines. Platforms 1- 10 are constructed of brick with bitumen surface. Platforms 11 and 12 are concrete. Lawson Street Overbridge The northern end of the Station is defined by the Lawson Street Overbridge, completed in 1891, which carries Lawson Street across the tracks. The bridge is brick laid in English bond pattern and was constructed in 1891. The bridge has been altered and extended in various stages. Construction appears to be a combination of jack arch, steel girder and concrete slab. Air vents to engine dive on Platform 1 Platform 1 includes four brick ventilation air vents or chimneys for the engine dive line that runs underneath the station, allowing engines to traverse between the Sydney Yard and the Eveleigh Maintenance Centre. ESR steel framework and tunnels Above Platforms 11 and 12, exposed steelwork for an unfinished platform remains in place, completed . Unfinished tunnels also run north and south from this section of the station, indicating earlier plans for extensions that never proceeded. Footbridge, steps and canopies The footbridge and steps to platforms was largely upgraded in 1999, and features a covered area connected to the Overhead Booking Office and glazed viewing area with access to all platforms. Platforms 2-9 also feature modern metal canopies joining access stairs to the platform buildings which forms a covered area for commuters. This was installed in 1999 as part of a new overhead walkway and access stairs to each platform. The stairs are concrete treads with steel banisters and balustrades. A pair of decorative cast iron newel posts at the bottom of the stairway to Platform 1 are all that remain from the original lattice iron stairway that was removed in . Landscape The garden on Platform 1 runs along the western wall of the platform from the base of the stairs to the first building on the platform. Some garden plantings remain but it is not maintained to a high standard. Condition As at 10 June 2009, the station building, including the Overhead Booking Office, Station Buildings on Platforms 2-10, and ESR Platforms were all in good condition. The structures at Redfern Station are in good condition with the exception of the disused tunnels at the eastern end and the exposed steelwork frames which are rusted. At least one section of tunnel
