Public Release Year: 1985
Reference Number: JPL-SO-81
Category: Environment And Resource Management
Origin: NASA Running Resistance Technology

Abstract:
Running resistance, the combined resistance induced by aerodynamic drag and mechanical friction, absorbs about 16 percent of railroad budget and maintenance costs. In order to study these losses, AT&SF Railroad entered into a joint research project with the Jet Propulsion Laboratory. Various train configurations were tested when the resulting data was computer analyzed. The Coast-Down Technique was estimated at one percent accuracy. AT&SF is evaluating the data further.
