• Abstract:
  Federal Railroad Administration contracted with the Transportation Technology Center, Inc., Pueblo, Colorado, to conduct an ; investigation of passenger vehicle performance running through heavy point frog (HPF) up to speeds of 110 mph. A NUCARS® ; simulation study was performed with various conditions of the track and vehicle systems, and for each case the results ; demonstrated that the HPF can be used successfully for Class 6 track speed with passenger equipment. The work has produced the ; following railroad impacts: ; - Analytical results of HPF performance with passenger equipment traveling over these sections at speeds up to 120 mph ; - Results contribute to assessment of the potential risks and dynamic effects of HPFs ; - Evaluation of HPF application to high-speed rail (HSR) operations ; The work has produced the following recommendations: ; - The limited test data performed on the Chicago – St. Louis HSR line provided good validation of NUCARS simulation ; models. However, the test was run at 79 mph. It is recommended to perform dynamic testing with passenger equipment and ; test the vehicle response and wheel/rail forces going through the HPFs at speeds up to 110 mph.
