Lateral Stability of Ballast - Ballast and Foundation Materials Research Program
This report presents the results of the lateral stability study of the Ballast and Foundation Materials Research Program. Full-scale lateral stability tests were conducted with a 2-rail, 3-tie system using slag, crushed limestone, and gravel as ballast. Various parameters including Peak...Structural Adequacy of Freight Car Truck Castings and Wheels
The structural adequacy of freight car truck castings and wheels to resist fatigue damage is reviewed. The environmental load data described in an earlier report under this program and additional load data which have only recently become available are used to calculate the expected fatigue life...The U.S. DOT/TSC Train Performance Simulator
A Train Performance Simulator (TPS) is a computer program which simulates the operation of a train over a railway route. It may be used for a variety of purposes to determine the effects of some operational strategy or equipment change upon schedules and energy consumption. The general...Potential Means of Cost Reduction in Grade Crossing Motorist-Warning Control Equipment. Volume II. Comparison of Solid State and Relay Devices and Techniques
Consideration is given to the properties of solid-state circuits, miniature relays and large gravity-operated relays when applied to control systems for grade crossings equipped with train-activated motorist warnings. Factors discussed include original cost and service-life cost, vulnerability to...SOFA 2016 3rd. Quarter Update
