Filter by Keyword9 report(s) found with railroad tracks in the keywords field 1 - 9 of 9 Tracks are a critical and expensive railroad asset, requiring frequent maintenance. Railroads companies often rely on the accurate localization and identification of the track anomalies that could cause serious damage to infrastructure, environment, and the traveling public. However, the deployed method... Federal track safety regulations require railroads to inspect all tracks in operation as often as twice weekly. Railroad companies deploy expensive and relatively slow methods using human inspectors and expensive automated inspection vehicles to inspect and monitor their rail tracks. The current practices... A model of investment in basic track components is estimated from 1985-2008 data for Class I railroads. Network size is measured in miles of road (MOR), while traffic is measured in revenue gross ton-miles (RGTM). In addition to MOR and RGTM, the model includes railroad indicator and time variables.... Investigations into the effects Z-spiking with fiber reinforced polymer (FRP) rods have on the flexural stiffness and repair of deteriorated railroad crossties were conducted. These tests were conducted to provide a pilot study for an ultimate goal of repairing full-scale bridges. This report presents... Six major railroads provided the Transportation Technology Center Inc. (TTCI) with defective rail that had been removed from service. The rail, which contained a variety of defects, was placed into a gauntlet track at the Transportation Technology Center (TTC). This paper is the assessment of those six... Through deregulation, the railroad industry has rationalized its services across the nation. Since 1980, this has lead to the abandonment of over 33,000 miles of rail line in the United States. While this has improved the efficiency and financial viability of rail carriers, it has adversely affected... The general objective of this study is to identify the nature and costs of potential short line railroads in North Dakota as a means to mitigate effects of branch line abandonment. This report is a synopsis of North Dakota grain production and marketing patterns, as well as how rail line abandonment affects local grain shipments and prices. Rail line abandonment is a process designed to allow railroads a means for disposing of unprofitable lines. This paper discusses this process. |
