This examination considers normative urban design criteria in relation to concepts of sustainable, transit-supportive built environments. This notion required a conceptual framework which accommodates the sophisticated and subjective aspects of regional design. Further, a visual methodology capable of accumulating significant quantities of data relevant to urban design was requisite. A qualitative case study strategy of inquiry was therefore adopted. Three UK recycled railway corridors were selected as case studies and considered independently and interdependently. This comparative analysis was predicated upon a variety of sources; archival, documentary and observational. This research uncovered urban design truths in the empirical context of recycled railway corridors. A high proportion of the instances examined in this research illustrate perfunctory urban design responses to public transit spaces, both in the regional and neighbourhood contexts. These instances were evocative of influences that prompt homogenisation in the anatomy of the built environment, with the automobile-dominated landscape showing prevalence. In these instances, normative urban design qualities were largely absent from the public realm. In lieu of these qualities ‘anywhere’ design responses, that failed to address issues of authenticity and place specificity, occupied those important spaces that relate to the public transit systems. However, this condition was not ubiquitous. This research examined instances where careful interdisciplinary ‘joined-up thinking’ has led to a set of place specific, transit supportive urban designs. Here, the opportunities inherent at the convergence of public transit systems and the human scale public realm have been taken advantage of. This has been achieved through the consideration of issues such as palimpsest, rootedness and place specificity, which have resulted in exemplars of bespoke, transit supportive urban designs. Acknowledgements There are many whom require acknowledgement for their help in the completion of this thesis, from both personal and professional positions. The foci of this research, the urban design of recycled railway corridors, was first examined through a design exercise as opposed to the empirical research it is now. This design exercise was conducted under the tutelage of Dr Timothy Brindley. The task set was to accommodate a relatively large amount of new dwellings on ex-industrial brownfield sites within the city of Leicester. As part of the city-wide site analysis for this project, it soon became apparent that a significant amount of that land use typology were linked, by what it transpired to be, the disused Great Central Railway alignment. This prompted a change in perspective from a city-wide to a regional outlook in order to incorporate sites beyond the city boundary that were linked by what was perceived at the time to be a dormant asset (see below). This design task, and the further questions which it prompted, was in essence, an embryonic exercise for this research. Both this design exercise and the resulting theoretical review (for which Dr Timothy Brindley was also dissertation supervisor), introduced the researcher to the notion of transit supportive urban design theory. This brief exercise in applying ‘Transit Town’ principles as part of a design exercise highlighted the paradigm’s inherent complexities to the researcher. Once the opportunity arose, a Ph.D. proposal was submitted with the intention of examining these complexities in detail. This researcher owes Dr Timothy Brindley a debt of gratitude for recognising the scope of, interest in, and significance in this topic, especially considering other academics were dismissive of the ideas. Personally the researcher has a complex relationship with the issue of disused / recycled railway corridors which can be difficult to articulate without becoming sentimental. The image below is of a dissed railway line close to the Derbyshire / Nottinghamshire boarder. This line, having just passed under a bridge that previously carried the dismantled ‘Ripley Rattler’ tramway, is a spur towards the Loscoe Colliery off the Midland Railway between Nottingham and Sheffield. This Image also shows to the right the garden of my childhood home and to the left housing that was built during the researcher’s lifetime, which turns its back to the disused line. Phenomena such as this have been formative. I have distinct memories of walking this and other ‘railway solemn’ (Association of Train Operating Companies, 2009), wondering what happened to the trains1 and what the future holds for such spaces? A curiosity that is extending through and beyond this research. This curiosity is at the bequest of my late father Alan2, whose intelligence, critical ability and insatiable pursuit of knowledge I could only hope to emulate. I owe a debt of gratitude to my close family; my Mother, Aunt and Partner. Without their patience and considerable financial support this research would not have been possible. This gratitude also extends to my supervisor, Tim Heath. Without his patience, advice, time, support and encyclopaedic knowledge of urban design this research would not have been 1 Other instance of the researcher finding themselves at places that used to be railway lines: Childhood memories of Victoria Bus Station in Nottingham on the site of Victoria Railway Station, attending the re- opening of Langley Mill Railway Station with junior school, playing football adjacent to Newstead Railway Station during the reinstatement work of the Robin Hood Line, visiting a family members house adjacent to the reinstatement work of the Robin Hood Line, working as a labourer in a cabinet making factory on the site of the closed Great Central Railway in Hucknall, walking to university (undergraduate) along a disused line that ran along the bottom of the garden. 2 Who would have most likely been in the same A-level group as one of the key authors in this text, had he been allowed to attend sixth form college at the age of 16, as opposed to going straight into work for Raleigh, at the site that is now the University of Nottingham’s Jubilee Campus. possible either. Further, I have enjoyed our deliberations over, what I hope, has been a mutually interesting topic. My gratitude also extends to Dr Kim Lawson, whose advice, coaching and compassion have enabled the completion of this thesis.
