platform and runs parallel to the footbridge. The structure is an iron and steel girder and jack-arch bridge with a concrete deck, brick piers on all platforms and brick balustrades . The overbridge is in good condition. However the brickwork parapets show traces of organic growth. Based upon visual inspection the overbridge appears to have retained most of its original fabric including the plate girders, the brick piers and brick balustrades. Landscape/Natural Features The palm tree on Platform 1 and 2 is possibly the tree that was planted on the platform in the 1920s The palm tree is in a moderate condition. Moveable Items The bench seats in the waiting room of the platform building (1926) are original although they have been added onto (in a sensitive manner) and converted into shelves for storage. Archaeological Potential The site has moderate archaeological potential. The north-eastern platform, bordering Hennessey Street along with the discontinued and highly dilapidated section of the existing footbridge is of substantial archaeological value. However, as the platform and these associated features are no longer in use and have been are in disrepair it is possible that some significant original fabric may have been lost. Heritage listing Croydon Railway Station has State significance as the existing station arrangement with railway structures dating from the 1892 quadruplication and 1927 sextuplication of the line is illustrative of the expansion of the railways in the late 19th and early 20th century undertaken to accommodate suburban development along the line and to the west. Designed under the direction of Commissioner Edward Eddy, the extant 1890s platform building is largely intact and it demonstrates the first use of island platforms in NSW and is one of four extant examples of this type of station building design, known as the "Standard Eddy". The 1920s "initial island" building and 1940s "Railway Stripped Functionalist" building have aesthetic significance and together are able to demonstrate the shift in the architectural styles employed by the railways during the first half of the 20th century. The 1890s footbridge is significant and relatively uncommon in terms of its overall form and construction technique as it was one of the first footbridges in the Sydney Metropolitan region which has reinforced concrete employed for its piers and columns. The 1920s palm tree is significant as it provides insight into the landscaping patterns that existed at Croydon station and others stations along the line
