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...
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...
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, ..

Mathematical representations of railroad track geometry variations are derived from time series analyses of track measurements. Since the majority of track is free of anomalies (turnouts, crossings, bridges, etc.), representation of anomaly-free
track is first considered. Anomalies are then...
Safety requirements for high cant deficiency rail passenger service address the dangers of vehicle derailment, track damage and unreasonable risks to standing passengers of falling. Safety criteria concerning vehicle derailment and track damage have been well developed. Those applicable to...
This is report number 22 in a series .covering research performed by the National Institute of Standards and Technology (NIST) for the Federal Railroad Administration (FRA). This report covers a project by the Materials Reliability Division (formerly the Fracture and Deformation Division) to...
Tests were performed on the Peacekeeper Rail Garrison Launch Control Car(LCC), EMS-2 according to specifications in Chapter XI of the AAR's, Manual of Standards and Recommended Practices. The tests included vehicle characterization, service worthiness, and track worthiness. These tests address...
