APTA Technical Document on Streetcars

The Circulator Trackway Report was created to bring back some of the technical design skills we lost with the disappearance of street railways. An example of the kind of information you can find in the document ...

Problems typically found on track of questionable design and/or construction are:
  • Improper gauging of track and guard rails.
  • Use of apparently railroad-based designs not suitable for Light Rail Circulator System rolling stock with street
  • railway wheels and/or the curvature employed on the system. (See Figure 3.)
  • Failure to understand the criticality of certain crucial track dimensions and tolerances under small radius circumstances.
  • Employment of design details that increase the cost and complexity but have no payback in terms of performance or utility
