Crippling Test Of An M1 Passenger Railcar
Occupied volume integrity (OVI) refers to a passenger railcar’s ability to preserve interior cabin space for passengers and crew during an accident. By preventing or minimizing structural deformation of, or intrusions into the rail vehicle's interior, passengers are better able to withstand,...Autonomous Broken Rail Detection Technology for Use on Revenue Service Trains
ENSCO Inc. in collaboration with Virginia Tech (VT) has developed, tested, and integrated a wavelet-based broken rail detection algorithm. This algorithm utilized acceleration data that was recorded by the Vehicle/Track Interaction (V/TI) Monitor, an autonomous measurement system that proved...Track Profile Approximation Using Railcar Body Acceleration Data
Accelerations are frequently measured from the car body of a rail vehicle, which is mounted above one or more suspension systems. Measuring accelerations in the car body is largely done for convenience, as mounting an accelerometer to a truck or axle of a railcar is more cumbersome than simply...Broken Rims in Railroad Wheels
Broken wheels are one of the most common types of equipment-caused train accidents. The failure of rail car wheel rims, which are usually the result of shattered rims or vertical split rims (VSR), are the leading cause of wheel-related accidents, and they are increasing as a percentage of all...Locomotive Emissions Measurements for Various Blends of Biodiesel Fuel
The objective of this project was to assess the effects of various blends of biodiesel on locomotive engine exhaust emissions. The emission tests were conducted on two locomotive models, a Tier 2 EMD SD70ACe and a Tier 1 Plus GE Dash9-44CW, using two baseline fuels: (1) conventional EPA ASTM No. 2-...Fiscal Year 2014 Enforcement Report
The following is an annual report published by the Federal Railroad Administration (FRA) summarizing settled claims for civil penalty violations of Federal railroad safety and hazardous materials statues, regulations and orders during Federal Fiscal Year 2014. The report also contains a...
