Transportation Technology Center, Inc. (TTCI) is investigating an alternative crosstie design to conventional concrete crossties for bridge approaches. The project is being co-sponsored by the Federal Railroad Administration (FRA) and the Association of American Railroads (AAR).
This report summarizes the studies of a program to establish the technology
of magnetic suspension for ultimate use in a passenger-carrying high-speed
ground transportation (HSGT) system - at speeds on the order of 134 m/s
(300 mph). Magnetic Levitation (MAGLEV) is one of the advanced vehicle...

The analyses required to calculate the aerodynamic effects of tunnel entry, tunnel venting, and multiple vehicle motions in open ended tunnels are presented. Results for several cases of open ended tunnel travel and various entry configurations are presented and described. The effects of an earlier...
The effects of manufacturing method, chemical composition, heat treatment, temperature, and loading rate on the plane strain fracture toughness KIC of railroad wheels have been determined. Carbon content of the wheels is shown to be the principal factor which controls their toughness. One...
This report reviews the California Railroad-Highway Grade Crossing Program, analyzing the factors influencing the reduction in grade crossing accidents. The report concludes that the greater than average success in grade crossing safety in California has resulted from the long standing financial...
The present study is part of a program, sponsored by the Office of Research, Development and Demonstrations, Federal Railroad Administration, to investigate efficient, cost-effective methods of high speed ground transportation for intercity travel. Previous aspects of' the program have...
Transportation Technology Center, Inc. conducted a side impact test on a DOT-111 tank car to evaluate the performance of the tank car under dynamic impact conditions and to provide data for the verification and refinement of a computational model.
The tank car was filled with water to...
