during the early 20th century. Croydon railway station was listed on the New South Wales State Heritage Register on 2 April 1999 having satisfied the following criteria. The place is important in demonstrating the course, or pattern, of cultural or natural history in New South Wales. Croydon Railway Station is historically significant as the existing station arrangement with extant railway structures dating from the 1892 quadruplication and 1927 sextuplication of the line is able to clearly illustrate 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. The extant 19th and 20th century platforms, buildings, footbridge and overbridge are collectively able to demonstrate a former era of travel. The place is important in demonstrating aesthetic characteristics and/or a high degree of creative or technical achievement in New South Wales. Croydon Railway Station has aesthetic significance with its 1890s "Standard Eddy" building which has been altered in terms of its relocation from a typical island platform to a wayside platform, but still retains characteristic features of this type of station building namely the cantilevered awnings with wide fascia. The 1920s "initial island" platform building has been altered internally but it retains a linear form, gable roof and integrated awnings. The 1940s "Railway Stripped Functionalist" building with its cantilevered awnings and steel-framed windows has typical features of this type of station building and is aesthetically significant as it demonstrates a shift in the style from earlier "initial island" platform buildings. The overhead booking office has been altered internally but it retains characteristic features of such buildings, namely the pre-cast concrete panels with weatherboard construction appearance and its location on the footbridge. The Croydon Station footbridge has technical significance as it was the first time within the Sydney metropolitan area that reinforced concrete was used for the piers and columns of a footbridge.

The place has the potential to contribute to the local community's sense of place, and can provide a connection to the local community's past.
