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...

Innovative Concepts and Technology for Railroad-Highway Grade Crossing Motorist Warning Systems. Volume I. Overview and Concept Generation and Analysis

The document includes a general review of innovative conceptual and technical approaches to train-activated motorist warning systems for use at railroad-highway grade crossings, and also contains a specific report describing a study directed toward the generation, analysis and evaluation of...

Handbook for Railroad Track Stabilization Using Lime Slurry Pressure Injection

This handbook includes chapters dealing with the technology of lime injection, surface and subsurface soil exploration and laboratory testing, environmental considerations and safety precautions. In addition, there are appendices which provide state-of-the-art specifications for lime slurry...

A Bibliography on Rail Technology

The rail technology review provides assistance to a number of rail technology programs initiated by the Transportation Systems Center (TSC) for the Federal Railroad Administration (FRA). The results of a search and review in four specific areas in the field of rail technology are presented in the...

Probability of Detection Evaluation Results for Railroad Tank Car Nondestructive Testing

The Federal Railroad Administration (FRA), Transportation Technology Center, Inc. (TTCI), and rail industry participants have performed probability of detection (POD) assessments to evaluate nondestructive testing (NDT) technologies, which are prescribed by Title 49 of the Code of Federal...

Technical Feasibility Study of Railroad Electrification with High Voltage (10-50 kV) Direct Current

High-voltage (10-50 kV), direct-current (HVDC) power distribution may prove to be an economically and technically attractive option for railroad electrification. There may be potential economic advantages in both wayside installation and operation, and in the propulsion equipment aboard the rolling...

Measurement Plan for the Characterization of the Load Environment for Cross Ties and Fasteners

This report was prepared as part of the Improved Track Structures Research Program sponsored by the Office of Rail Safety Research of the Federal Railroad Administration. The report is a planning document for a track measurement program to obtain data on the service loads and reactions of cross...

High-Speed Rail Turnout Literature Review

High-speed rail (HSR) turnout design criteria generally address unbalanced lateral acceleration or cant deficiency (CD), cant deficiency change rate (CDCR), and entry and exit jerk. Various countries have adopted different design values for their HSR systems based on their unique experiences and...

Rail Integrity Alert System (RIAS) Feature Discrimination

This report describes GE Global Research’s research, in partnership with GE Transportation, into developing and deploying algorithms for a locomotive-based inductive sensing system that has a very high probability of detecting broken rails with very few false-positives. These algorithms are...

Train-To-Train Rear End Impact Tests. Volume III. Appendix A: Impact Test Data. Appendix B: Report of Inventions

Nine train-to-train rear end impact tests were performed, and tests were documented. Volume III is an appendix to Volume II. It contains the original data of the impact test.
