The impetus for this dissertation was my research work named "Echidnas of the Pedestrian Area: the Female Wandering Flâneries". The main theme of the work was the wandering figure of the female sex, the flâneuse *, and the dangers-stimuli (hence the term echidna) presented by her roaming. The flâneuse figure, according to one of the conclusions of the work, embodies the model of the wandering woman, who carries out a series of walkabouts that act as creative stimuli for her. Embodying myself the role of the flâneuse, I made a series of wanderings in the cities of Thessaloniki and Volos and the stimuli of these wanderings were recorded through the photographic lenses. Although the photographic material came from different geographical areas, it had some similarities in terms of its content:  the "cemeteries". This peculiar type of cemetery connects my previous work with the present one, which focuses on train cemeteries.

 These cemeteries, which are indefinite in terms of size and extent, are scattered throughout the geographical area of Greece, creating urban gaps, discontinuities, frozen shells and leaving a large chapter of Greek industrial history at the mercy of time and their occasional visitors. During the investigation, the railway network was examined as a sum of subnets consisting of points-stops connecting different places with each other through a route and the individual sections have characteristics of the area to which they belong. Therefore, the railway network was examined as a system that comes in contact with different places, customs and traditions, whilst emphasis was laid on maintaining the network's identity and detecting the traditional boundaries of railway architecture (this concerns the architectural structure of the railway network itself as well as the infrastructure and roadbed system that supports it).

 The active and inactive network, the use and non-use, sparked thought and set goals. More specifically, the aim was to find the elements that make the railway network dysfunctional, to present its strengths that can be exploited, and finally to submit a proposal that will revive the railway heritage by providing new growth prospects and a strategic return.

* Flâneuse = A term derived from the corresponding male figure flâneur, introduced by the French intellectual Charles Baudelaire.
