The signal box on Platform 2 is a representative example of its type, adapted to suit the side platform rather than the more typical island platform. It is a well detailed building designed and orientated to maximize views of the lines in each direction. The Mount Victoria barracks has a simple gabled form with wide verandahs and has been modified significantly yet still provides an example of a former rest-house facility established within close proximity of the railway line. The overall aesthetic character of the station is further enhanced by the setting of the station within the rock escarpment, a typical natural setting of the Blue Mountains stations, featuring a collection of numerous flora ranging from mature trees, shrubs and potted plants along both platforms. The place has a strong or special association with a particular community or cultural group in New South Wales for social, cultural or spiritual reasons. 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. The place has potential to yield information that will contribute to an understanding of the cultural or natural history of New South Wales. The Mount Victoria Railway Station Group has a high degree of research potential for its demonstrative ability in providing construction techniques and architectural character of various types of buildings in one station. The station building on Platform 2 is of particular research significance for its staged construction over time to accommodate different staff and passenger needs. The site of the former SM's cottage also has archaeological potential. The place possesses uncommon, rare or endangered aspects of the cultural or natural history of New South Wales. The Mount Victoria Station group is a rare Victorian era railway station combining a number of individually significant buildings and structures. The signal box is one of a few brick on platform signal boxes remaining in the state. The Railway Refreshment Rooms, though no longer used for their original purpose, are rare examples of such railway facility associated with the station's important location. The barracks are relatively rare in the metro area (8 in 2009) though at least 37 remain in NSW. While of later construction it is representative of the late 1890s standard design of rest-house that provided accommodation to railway staff. The footbridge is rare as an intact example of a standard Warren Truss trestles and stairway with Hardie Board long plank timber deck and channel iron stair stringers as almost all similar footbridges have been replaced with concrete. The place is important in demonstrating the principal characteristics of a class of cultural or natural places/environments in New South Wales. Mount Victoria Railway Station Group is a representative example of a substantial railway station complex combining various types, periods and styles of buildings dating from the 19th Century and early 20th Century, each individually representing their standard designs and types.
