Even in some modes that have been more fully addressed, there is not universal consensus as to what constitutes SGR within the U.S. (or Europe) for all asset classes.  Transit is a good example. The Transportation Research Board of the National Academies’ (TRB) 2011 International Transit Studies Program: Report on the Spring 2010 Mission describes the state of the practice as such; “At present, there is no universally accepted definition for “state of good repair” for public transit assets; rather, individual transit agencies typically employ their own internal definitions (if they have even adopted a definition), and these definitions can vary appreciably”
