The Marrickville station complex consists of two station buildings: the Platform 1 building (1895) and Platform 2 building (1911), with associated platforms built at the same time, along with a booking office on Platform 2 (1917). It also includes two sets of pedestrian steps: a northern set (1917) and a southern set (mid-1980s), along with an overbridge on Illawarra Road (1911). Marrickville railway station consists of one wayside platform to the south and an island platform to the north. Passenger rail only uses the south side of the island platform, with the Metropolitan Goods Line running on the north. The station buildings are original, as is the booking office at the western end of Platform 2. The station is accessed via
stairs or
lifts to both platforms from the concourse, or at a level entry onto Platform 2 from Station St. Illawarra Road is a major commercial shopping strip. ;Platform building – Platform 1 (1895) The Platform 1 building is a rectangular polychromatic face brick building with gabled roof and surrounding cantilevered
awning clad in corrugated roof sheeting. The exterior was restored to original condition during upgrades in 2016. It contains a number of rooms, such as a ticket office, waiting rooms and toilets. The ticket office is no longer in use, as all paper tickets have been phased out on the Sydney Trains network in favour of smartcard ticketing (
Opal card). All other rooms, except the toilets, are also locked off and not accessible to the public. ;Platform building – Platform 2 (1911) The Platform 2 building is a rectangular face brick building with gabled roof and integral shallower sloped single cantilevered awning. Internally, the building comprises a general waiting room; ladies room and ladies toilets, a store and men's toilets. As with the building on Platform 1, the exterior was restored during the 2016 upgrades. The whole building is closed to the public, mostly used as a storeroom. ;Booking office (1917) The original timber framed overhead booking office dating from 1895 was demolished and the existing timber framed booking office located on Platform 2 built in 1917–18. The building is a simple, rectangular
weatherboard clad timber-framed structure, with a
gable roof clad in corrugated steel which extends as an awning with exposed
rafters on the platform side. The building is currently used as a storeroom. ;Platforms Platform 1 has an asphalt surface with the original brick face and edge. The northern side of this platform (not used and fenced off) has a brick edge with the original brick face. Platform 2 also has its original brick face but with a concrete edge. Both platforms are approximately 160 metres long, enough to fit an 8 carriage suburban train. Both platforms are slightly curved and are equipped with LCD screens displaying next trains, together with automated announcements. Due to the lack of shelter at the eastern end of both platforms, there are no screens at this end. There are two small waiting shelters around the middle of platform 1, to encourage waiting passengers to spread out when it is raining, as all the station buildings are at the western end of the platform. ;Overbridge (1911) Steel girders and a concrete slab supported on central brick piers and side brick abutments. The original access stairs from the overbridge to Platform 1 had the original steel stringers but had new concrete treads and a new steel
balustrade. The later stairs on the south were constructed from steel stringers supported on steel
columns and with precast concrete treads. Both of these stairs were removed and replaced by the concourse during the 2016 upgrades. == Heritage listing ==
