Characterization of Locomotive Tractive Effort from Electrical Power to the Traction Motors
Experiments to be performed on the FAST track at the Transportation Test Center required a method of measuring train resistance and related fuel consumption in moving the train. Previous experiments had shown that the Roll Dynamics Unit (RDU) in the Rail Dynamics Laboratory might be used as a...Effects of Rail Profile Variation
Railroads in various countries including the United States have found that benefits may be obtained by grinding rails to an 'asymmetric' profile rather than to the original 'new' rail profile. To investigate these findings further, the Federal Railroad Administration (FRA) and the Association of...Safety of High Speed Magnetic Levitation Transportation Systems. Magnetic Field Testing of the TR07 Maglev Vehicle and System. Volume 2. Appendices.
The safety of various magnetically levitated (maglev) and high speed rail (HSR) trains proposed for application in the United States is of direct concern to the Federal Railroad Administration (FRA). The characterization of electric and magnetic fields (EMF) emissions, both steady (dc) and produced...Performance of Degraded Roller Bearings
Concerns over railroad bearing failure prompted a test to be conducted to measure the rate at which degraded bearings overheat under service conditions. A test consist which included a locomotive, a data collection car and four test cars containing 24 subject bearings was utilized. The bearings...Safety of High Speed Magnetic Levitation Transportation Systems - Preliminary Safety Review of the Transrapid Maglev System
The safety of various magnetically levitated trains under development for possible implementation in the United States is of direct concern to the Federal Railroad Administration. This report, one in a series of planned reports on maglev safety, .. 'addresses safety issues related to a specific...FRA Announces $10 Million for States to Improve Highway-Rail Crossings, Track Along Energy Routes
WASHINGTON – The Federal Railroad Administration (FRA) today announced that it is soliciting applications for $10 million in competitive grant funding available to states to improve highway-rail grade crossings and track along routes that transport energy products like crude oil and...
