Once deployed, their maintenance depends Current state-of-the-art maintenance operations within the on the data collected on their status, and the decisions on due railway infrastructure are based on the concept of “preventive” or corrective actions. The more regular this data collection and “on-condition” maintenance. However, they only consist of decision cycle is, the better confidence their operator has on periodical check-ups and substitutions of parts when a failure is effective and proper service. Proactive maintenance, in general, detected. These tasks are carried out at given periodical intervals targets exactly this: rather than scheduling maintenance actions designed to mitigate risk with a considerable safety margin based on operating hours or servicing volume, actions should be involving having to send maintenance staff to the asset site on a taken when it is really needed. This requires the effective regular basis, exposing them to the usual safety risks of a running combination of data collection, analysis, presentation and decision railway [11]. making processes.

FOR IMMEDIATE RELEASE AT THURSDAY, OCTOBER 14, 1999 (202) 514-2007 WWW.USDOJ.GOV TDD (202) 514-1888 JUSTICE DEPARTMENT REQUIRES DIVESTITURE IN HARSCO CORPORATION’S ACQUISITION OF RAILROAD MAINTENANCE ASSETS Harsco to Divest Pandrol’s Switch and Crossing, and Transit Grinder Assets WASHINGTON, D.C. -- The Department of Justice today announced that it would require Harsco Corporation to sell machinery and services used in railroad maintenance to resolve competitive concerns over Harsco’s $89 million acquisition certain of assets of Pandrol Jackson Inc. and Pandrol Jackson Limited. The Department said the deal, as originally proposed, would have been anticompetitive, resulting in higher prices and lower quality for these products and services. The Department's antitrust lawsuit and proposed consent decree were filed today in federal court in Washington, D.C. The consent decree, if approved by the Court, would resolve the suit. According to the complaint, the proposed merger would have substantially lessened competition, since Harsco and Pandrol are the only two manufacturers of switch and crossing and transit grinding equipment and the only two providers of railroad switch and crossing grinding services in North America. Switch and crossing grinders and transit grinders are machines designed to restore the tracks of railroads and transit systems to their original shapes and are used to repair deformations caused by the rubbing of train wheels on rails used in railroad track switches, railroad track crossings, and transit systems. “Without this divestiture, railroads and transit systems would have had only one choice for this type of railroad maintenance equipment and services,” said Joel I. -

It is the main reason Accepted: for choosing to base this study on this subsystem. Published: Intelligent data processing allows understanding the real reliability characteristics of the assets to be maintained. The first objective of this Keywords: research is to determine the S&C reliability characteristics based on Reliability field data collection. Because field failure data are typically strongly Availability censored, an especial statistics software package is developed to Weibull model process field failure data, as commercial packages have not been found satisfactory in that respect. The resulting software, named RDAT® Switches (Reliability Data Analysis Tool) has been relied upon for this study. It RDAT is especially adapted for statistical failure data analysis. In the next step the availability of studied switches and crossings is estimated based on the reliability characteristics founded in the first step. 1.

These guidelines are not standards, and are intended as examples for various rail-highway configurations. A diagnostic inspection team will determine the ultimate design for each railroad crossing project. The ultimate design shall be compliant with the Texas Manual on Uniform Traffic Control Devices (TMUTCD) and American Railway Engineering and Maintenance-of-Way Association (AREMA) standards. The guidelines are broken down into 3 main categories: ♦ Design of Active Device Configurations ♦ Design of Railroad Crossings Adjacent to Traffic Signals ♦ Design of Railroad Crossing Closures and Consolidations Guidelines are subject to change.

Chapter 14 Yards and Terminals1
CHAPTER 14 YARDS AND TERMINALS1 FOREWORD This chapter deals with the engineering and economic problems of location, design, construction and operation of yards and terminals used in railway service. Such problems are substantially the same whether railway's ownership and use is to be individual or joint. The location and arrangement of the yard or terminal as a whole should permit the most convenient and economical access to it of the tributary lines of railway, and the location, design and capacity of the several facilities or components within said yard or terminal should be such as to handle the tributary traffic expeditiously and economically and to serve the public and customer conveniently. In the design of new yards and terminals, the retention of existing railway routes and facilities may seem desirable from the standpoint of initial expenditure or first cost, but may prove to be extravagant from the standpoint of operating costs and efficiency. A true economic balance should be achieved, keeping in mind possible future trends and changes in traffic criteria, as to volume, intensity, direction and character. Although this chapter contemplates the establishment of entirely new facilities, the recommendations therein will apply equally in the rearrangement, modernization, enlargement or consolidation of existing yards and terminals and related facilities. Part 1, Generalities through Part 4, Specialized Freight Terminals include specific and detailed recommendations relative to the handling of freight, regardless of the type of commodity or merchandise, at the originating, intermediate and destination points. Part 5, Locomotive Facilities and Part 6, Passenger Facilities relate to locomotive and passenger facilities, respectively. -
