Table 2: Some national railway museums in the world. Museum buildings are generally either purpose-built or conversions, and museums should be established or managed based on an understanding of both the form and function of these buildings [4]. Railways, buildings, and related facilities in the TRW are important national heritage sites; however, the TRW was not set up for the purpose of a museum, and as such, a lot of data, objects, maps, and documents were not saved, and trains are scattered in different places around Taiwan. The preserved TRW is now under preparation and construction to become an NRMT; in this process, many things should be done, e.g., measuring the size of the heritage location, surveying the features, renovating the broken parts, collecting historic and valuable objects, interviewing senior staff of the TRW, recording the processes of maintenance, determining function districts, and planning the exhibit layout, and so forth. It is a long and difficult road ahead for the TRW transition into an NRMT. The museum is a multilayered and complex environment representing a diverse set of service units, such as exhibition space, store space, administration space, restaurant space, and shop space to match museums' multigoals [4]. The layouts of the exhibition space are quite hierarchical; the whole museum arena, the museum building's type, the configured shape of the entire exhibition space, and the individual display exhibition space all create spaces that lead to other spaces, giving visitors multidirectional views. A rough rule of thumb for space allocation is that, for the reception/visitor facilities, collections storage, displays/exhibitions, and support services, each function space is 25% of the museum. About 20% of the gallery is for displays, and about 80% of the gallery is used for the circulation area [4] (Figure 1). Although some researchers have a different understanding regarding the appropriate percentage of each function space [14; 15], the approach suggested by [PERSON] and [PERSON] is accepted in this paper to develop some planning principles (Table 3).
