High-Speed Non-Electric Locomotive Noise Measurements

This report summarizes the methods and results of train noise measurement carried out on August 30, 2001 at the Transportation Test Center in Pueblo, Colorado. The measurements were performed by Harris Miller Miller & Hanson, Inc on behalf of the Federa lRialroad Administration, under...

The Sound Environment in Locomotive Cabs

Measurements of the sound environment in locomotive cabs including audible warnings perceived by crew members are described. Data was collected during two different test runs under diverse conditions, one on the Long Island R.R. and the other on the St. Louis-San Francisco Railway. The crew's...

Flywheel Energy Storage Switcher

An indepth study of the application of flywheel energy storage to the railroad switchyard locomotive was conducted to determine the practicality and viability of such a system. The system, as originally conceived, required the use of separately excited fraction motors, and a major task of the study...

An Assessment of Railroad Locomotive Noise

Measurements of the noise generated by an SD40-2 diesel electric locomotive are described. The noise was measured in three types of moving tests: the first with the locomotive passing a 6-microphone array while under maximum power acceleration, the second with the locomotive simulating the...

Parametric Analyis of Railway Line Capacity

The problem of analyzing the capability of a rail line to absorb additional traffic has become increasingly important recently as various means of consolidating and expanding usage of the rail systems have been proposed. This report develops a systematic procedure for evaluating the potential...

Human Factors Survey of Locomotive Cabs

Purpose of the investigation was to review design of locomotive cabs from the human factors point of view. The following areas of human factors engineering are discussed: construction of cab interiors; design of controls and displays; atmospheric conditions in the cab; noise and vibration; seat...
