Investigation of Railroad Bridge Approach Problems along Heavy Haul Freight Lines

Under a contract with the Federal Railroad Administration (FRA), the University of Illinois at Urbana Champaign (UIUC) is investigating different factors that contribute to the problem of differential movement at railroad track transitions The research objective is to develop new design and...

Positive Train Control Shared Network

The Interoperable Train Control (ITC) Positive Train Control (PTC) Shared Network (IPSN) project investigated anticipated industry benefits and the level of support for the development of a hosted technological platform for PTC messaging across multiple railroads. A hosted network would reduce...

An Evaluation of Safety Culture Initiatives at BNSF Railway

Major safety culture (SC) initiatives initiated in the FRA Office of Research, Technology and Development (RT&D), such as Clear Signal for Action (CSA), the Investigation of Safety Related Occurrences Protocol (ISROP), the Participative Safety Rules Revision, and the Confidential Close Calls...

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...

Prototype Design and Test of a Collision Protection System for Cab Car Engineers

Advancements in the design of rail cars can potentially prevent the structural collapse of space occupied by a cab car engineer during a train collision. With adequate survival space maintained, the next crashworthiness objective is to minimize the consequences of any resulting secondary impact...

Control of Rolling Contact Fatigue on Premium Rails in Revenue Service

Effective rail maintenance strategies are essential for controlling rolling contact fatigue (RCF) and reducing wear of rails under heavy axle load (HAL) operations. In an effort to optimize rail maintenance strategies in revenue service, Transportation Technology Center, Inc. (TTCI) has been...
