This report defines Overhead Contact Systems (OCSs) and describes the function of OCSs for trolleybus and light rail systems. The report describes nonintrusive and intrusive designs, considering the overall visual impact of those designs on intersections or street segments and the complete effect that hardware has in any given location. It discusses the influence system design has on visual impact including the need for emergency wire and the use of one-way operation to minimize visual impact in trolleybus systems. Further, it investigates how the turning capability in trolleybus and light rail OCS design may have an effect on visual impact. The report considers the effect of curve design and the design of the electrical distribution systems on the appearance of light rail. An approach to evaluating the visual impact of trolleybus intersections is presented. This report concludes that the visual impact of OCSs can only be reduced if such reduction is made a specific goal throughout the design process.

TCRP report 155 provides guidelines and descriptions for the design of various common types of light rail transit (LRT) track. The track structure types include ballasted track, direct fixation ("ballastless") track, and embedded track. The report considers the characteristics and interfaces of vehicle wheels and rail, tracks and wheel gauges, rail sections, alignments, speeds, and track moduli. The report includes chapters on vehicles, alignment, track structures, track components, special track work, aerial structures/bridges, corrosion control, noise and vibration, signals, traction power, and the integration of LRT track into urban streets.

This is the only current and in print book covering the full field of transit systems and technology. Beginning with a history of transit and its role in urban development, the book proceeds to define relevant terms and concepts, and then present detailed coverage of all urban transit modes and the most efficient system designs for each. Including coverage of such integral subjects as travel time, vehicle propulsion, system integration, fully supported with equations and analytical methods, this book is the primary resource for students of transit as well as those professionals who design and operate these key pieces of urban infrastructure.
