The Needs and Desires of Travelers in the Northeast Corridor : A Survey of the Dynamics of Mode Choice Decisions

This report analyzes the needs and desires of travelers in the Northeast Corridor in four ways: the process of mode selection, the influence of the nature of the trip, the value considerations of travel, and the evaluations and images of the modes. It determines that mode selections are best...

Wayside Derailment Inspection Requirements Study for Railroad Vehicle Equipment

An analysis of the causes of the railroad equipment caused derailments was made. Data reported to the FRA was the primary source of derailment information; however, data from other sources were also available. Individual cause codes were consolidated into groups that had a common characteristic...

Vertical Track Modulus: Test Results and Comparison of Analysis Techniques

A vertical track response test was conducted at the AAR Track Structures Dynamic Test Facility. This test was intended to characterize the behavior of the track structure under increasing vertical loads. It was also intended to evaluate the different techniques available for the calculation of the...
