This report describes a research project to develop and verify habitability and human factors design criteria as applied to the design of a train rail car. A study of analogous conditions and similar environments was used to develop specific design solutions and design criteria for the rail cars. Verification of these design criteria was done via an iterative, usability test program with actual user personnel. The results of the first set of studies suggest that this test process improved the design of the system. The methods and results sections of this report contain specific design solutions and general comments that were developed during the test process.
