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 The railway station at Marrickville is significant as it is a station on the Sydenham to Bankstown Line which was constructed to relieve congestion on the Main South Line as well as to encourage suburban development and the growth of agriculture in the late 19th and early 20th century. The highly intact main platform building represents the period of transition from the boom time of the 1880s to the standardisation of NSW railway building design from the 1890s onwards, while the booking office on Platform 2 reflects a later period of expansion in the first quarter of the 20th century. Marrickville Railway Station is significant at a State level as the platform building demonstrates the high level of aesthetic design of the pre-1900 standard buildings, which included the use of polychromatic brickwork, decorative dentil coursing, ornate awning brackets and carved bargeboards. The platform building is intact and is representative of a small group of such ornate platform buildings including Canterbury and Belmore on the Bankstown Line. The platform building on Platform 2 provides an interesting contrast, demonstrating the simpler design of the standard platform buildings of the 1910/20s. Also of significance is the intactness of the weatherboard booking office which is unusual for being one of the few examples of a booking office located on a platform with street entry only and no access from the footbridge or overbridge, though the structure itself is representative of a standard design.
