Track-Related Research: Volume 1

TRB's Transit Cooperative Research Program (TCRP) Report 71a includes the results of three research tasks carried out under Transit Cooperative Research Program (TCRP) Project D-7, Joint Rail Transit-Related Research with the Association of American Railroads/Transportation Technology Center, Inc.: Alternative Broken Rail Technologies for Transit Applications; Prototype Demonstration of Film Coating to Reduce Noise and Wear in the Transit Environment; and In-Track Rail Welding in Transit Tracks. The report should be of interest to engineers responsible for design, construction, maintenance, and operation of rail transit systems.

Report Parts; Broken Rail Detection, Control of Wheel/Rail Friction, Wide-Gap Welding Techniques
