Trackway Infrastructure Guidelines for Light Rail Circulator Systems

The intent of this document is to be supplementary to TRB TCRP Report 57, Track Design Handbook for Light Rail Transit, and it is therefore focused on the important differences between “line-haul” light rail systems and Circulator light rail systems as they relate to trackway infrastructure. The guidelines, narrative, and illustrations provided in this report are intended to highlight many of the principal issues and concerns that should receive attention when designing a Light Rail Circulator System’s trackway infrastructure. Past experience of a number of transit agencies with wheel-rail incompatibilities requiring extra effort and cost to resolve have indicated that the attention to detail required to achieve the successful construction of such infrastructure is not to be underestimated.
