Higher Speed Freight Truck Performance Requirements Analysis
This proposed requirements document combines a set of requirements for high-speed freight car truck design and performance from the generally accepted standards in the U.S. Code of Federal Regulation (CFR), the Association of American Railroads (AAR) Manual of Standards and Recommended Practices (...Higher Speed Freight Truck Structural Analysis
Sharma & Associates, Inc. (SA) had previously (2005–2009) developed a higher speed freight truck under sponsorship of the Federal Railroad Administration (FRA). Under the current contract, SA was tasked with developing performance requirements for higher speed freight trucks, as well as...Freeze-Thaw Performance Testing of Whole Concrete Railroad Ties
Freezing and thawing durability tests of prestressed concrete ties are normally performed according to ASTM C666 specifications. Small specimens are cut from the shoulders of concrete ties and tested through 300 cycles of freezing and thawing. Saw-cutting these specimens may cause eccentricities in...A Job Analysis Design for the Rail Industry: Description and Model Analysis of the Job of Freight Conductor
This document provides a step-by-step description of the design and execution of a strategic job analysis, using the position of Freight Conductor as an example. This document was created to be useful for many different needs, and can be used as an example of how to conduct similar job analyses for...Development of an Operationally Efficient PTC Braking Enforcement Algorithm for Freight Trains: Appendices G-L
