Prototype Design and Evaluation of Hybrid Solid Oxide Fuel Cell Gas Turbine Systems for use in Locomotives
Hybrid solid oxide fuel cell-gas turbine (SOFC-GT) systems are among the most efficient and lowest emitting power generation systems conceived for use in locomotives. Their superiority was proven in stationary power applications with near-zero (natural gas operation) to zero (hydrogen operation)...Mixed Freight and Higher-Speed Passenger Trains: Framework for Superelevation Design
As the demand for higher-speed passenger trains increases, the disparity between freight and passenger operations also increases. On mixed-use rail corridors, the result is a bi-modal distribution of train speeds that complicates design of curve superelevation. To aid in making informed curve...Final Report - Guidelines for Testing of FRA Rear End Marking Devices
The implementation of Title 49, Code of Federal Regulations, Part 221 - Rear End Marking Device - Passenger, Commuter, and Freight Trains, requires the installation of certain highly visible marking devices for the trailing end of the rear car of all passenger, commuter. and freight train. It is...Improving Collision Post Crashworthiness of Legacy Locomotives
Modern locomotives are built to crashworthiness standards defined in Subpart D of Title 49 Code of Federal Regulations (CFR) Part 229 as well as the Association of American Railroads’(AAR) S-580 standards. Older locomotives, specifically the narrow-nose locomotives, were not designed to these...Heat Release Rate Requirements for Railcar Interior Finish: Appendices A Through E
This appendix is associated with Technical Report Heat Release Rate Requirements for Railcar Interior Finish and is summarized as such: Appendix A provides over 700 items in total, and over 650 of these include heat rate release (HRR) data from cone calorimeter tests; Appendix B contains cone...
Acoustical Warning Devices as Emergency Warning Systems, Phase 1
This program demonstrated the effectiveness of Acoustical Warning Devices (AWD) as secondary Emergency Warning Signals (EWS). The focus is to warn trespassers of an approaching train, through the development of an emergency warning signals that produce a sense of urgency, are noticeable to...
