Configuration Management (CM) has been traced back to the early 1950s where the principles were first applied as change management for computer hardware. CM was later expanded to early software development which has continued to the modern age. While the mantra has not changed in 60+ years — to define and manage change — updated techniques have streamlined the process making it easier to implement and more responsive in utilization in order to keep pace with changes for both micro (software) and macro (large-scale infrastructure project) applications. In order to advance the state of good repair (SGR) for rail and transit assets in the United States, CM has become an essential tool and must coordinate with Project Integration and Asset Management so that an organized process for change control with accurate record keeping can be established and maintained long term. The importance of CM has also been mandated at the Federal level for rail assets under 49 CFR 236. To bring wider understanding of CM to the industry, this paper will present Configuration Management and Project Integration techniques as applied to rail transportation infrastructure including assets that must meet Federal regulations, and it will discuss the coordination between CM, Integration and Asset Management under the SGR initiative. This is the final paper in a series that began in 2012, presented at the Joint Rail Conferences, and featured Denver Transit Partners (DTP) and the Denver Eagle P3.
