How Understanding a Railway's Historic Evolution Can Guide Future
College of Engineering, School of Civil Engineering University of Birmingham Managing Technical and Operational Change: How understanding a railway’s historic evolution can guide future development: A London Underground case study. by Piers Connor Submitted as his PhD Thesis DATE: 15th February 2017 University of Birmingham Research Archive e-theses repository This unpublished thesis/dissertation is copyright of the author and/or third parties.

Managing Technical & Operational Development PhD Thesis Abstract The argument for this thesis is that patterns of past engineering and operational development can be used to support the creation of a good, robust strategy for future development and that, in order to achieve this, a corporate understanding of the history of the engineering, operational and organisational changes in the business is essential for any evolving railway undertaking. It has been the objective of the author of this study to determine whether it is essential that the history and development of a railway undertaking be known and understood by its management and staff in order for the railway to function in an efficient manner and for it to be able to develop robust and appropriate improvement strategies in a cost-effective manner. -
